April 2015 marks the 200th anniversary of the great eruption of Tambora, on Sumbawa island, Indonesia. This eruption is the largest known explosive eruption for at least the past 500 years, and the most destructive in terms of lives lost, even though the precise scale of the eruption remains uncertain. The Tambora eruption is also one of the largest known natural perturbations to the climate system of the past few hundred years – having left a clear sulphuric acid ‘fingerprint’ in ice cores around the world, and evidence for a strong causal link to the ‘year without a summer‘ of 1816, and global stories of inclement or unusual weather patterns, crop failures and famine.

Much of what we do know about the eruption and its local consequences is down to the efforts of two sets of people: Stamford and Sophia Raffles; and Heinrich Zollinger. In 1815, Thomas Stamford Raffles was temporary governor of Java; the British having invaded in 1811. Shortly after the eruption of Tambora, he gathered reports from people in areas affected by the eruption, and put these together in an ‘account of the eruption of the Tomboro mountain‘, which was published first in 1816 by the Batavian Society for Arts and Sciences, and later published posthumously by his wife, Lady Sophia Raffles, in her biography of his life and works (Raffles, 1830).

There is a considerable scientific literature (see references below) which has documented the main phases of the eruption, which began in earnest on April 5, 1815, and built to an eruptive climax on 10 – 11 April 1815. It is thought that the volcano had been rumbling for some time prior to this, perhaps as early as 1812; and some of the contemporary records collected by Raffles suggest that the first ashy explosions may have begun by about April 1, 1815. An extract from a letter from Banyuwangi, Java, 400 km west of the Sanggar peninsula, describes this stage of the activity:

At ten PM of the first of April we heard a noise resembling a cannonade, which lasted at intervals till nine o’clock next day; it continued at times loud, at others resembling distant thunder; but on the night of the 10th, the explosions became truly tremendous. On the morning of the 3rd April, ashes began to fall like fine snow; and in the course of the day they were half-an-inch deep on the ground. From that time till the 11th the air was continuously impregnated with them to such a degree that it was unpleasant to stir out of doors. On the morning of the 11th, the opposite shore of Bali was completely obscured in a dense cloud, which gradually approached the Java shore and was dreary and terrific.

Heinrich Zollinger’s map of the inferred distribution of volcanic ash that fell across Indonesia following the eruption of Tambora in 1815. This may be the first example of an ‘isopach’ map of ash fallout from any volcanic eruption. From University of Oxford, Bodleian Library Collection.

The climactic phase of the eruption was very clearly described in an account by the Rajah of Sanggar, given to Lieutenant Owen Phillips, who had been sent to deliver rice for relief, and to collect information on the local effects of the eruption. ‘about seven PM on the 10th of April, three distinct columns of flame burst forth near the top of Tomboro mountain.. and after ascending separately to a very great height, their caps united in the air. In a short time the whole mountain next Sangar appeared like a body of liquid fire extending itself in every direction

In the main phase of the eruption, pyroclastic flows laid waste to much of the Sanggar peninsula, causing huge loss of life; and leaving a great collapse crater (caldera) where there had once been a tall volcanic peak.

Heinrich Zollinger was Swiss botanist, who moved to Java in 1841. In 1847, he led an expedition to Tambora and was the first scientist to climb to the crater rim since the eruption. In a short monograph, published in 1855, Zollinger describes his ascent of the volcano, documents the severe local impacts of the eruption, and details the numbers of people on Sumbawa affected by the eruption:

Location Killed in the eruption Died of hunger, or illness Emigrated
Papekat 2000
Tambora 6000
Sangar 1100 825 275
Dompo 1000 4000 3000
Sumbawa 18000 18000
Bima 15000 15000
Total 10100 37825 36725

Zollinger also estimated that at least 10,000 also died of starvation and illness on the neighbouring island of Lombok; and current estimates for the scale of the calamity are that around 60,000 people died in the region.

The bicentennial of the eruption of Tambora is a sobering moment to reflect on the challenges that a future eruption of this scale would pose, whether it were to occur in Indonesia, or elsewhere. Our present-day capacity to measure volcanic unrest should certainly be sufficient for a future event of this scale to be detected before the start of an eruption; but would we be able to identify the potential scale of the eruption, or its impact, in advance? Much remains to be done to prepare for and mitigate against the local, regional and global consequences of a repeat of an explosive eruption of this scale – and we still have more to learn by taking a forensic  look back at past events.

A volcanic retrospective: eruptions of the Soufrière, St Vincent

20 Jan

The records, reports and testimonies of past volcanic eruptions and their consequences contain a wealth of information from which we can learn valuable lessons. This, in a nutshell, is the starting point of one strand of the STREVA project, ‘Strengthening Resilience in Volcanic Areas‘, which is a large programme funded by two British funding agencies (NERC and ESRC) and directed from the University of East Anglia by Jenni Barclay. This week, researchers from the STREVA team met in a workshop on St Vincent, a luxuriantly vegetated volcanic island in the southern Caribbean, to see what can be learned from the past history of this volcano and how this learning can be used mitigate the risks of future volcanic activity.

Aerial view of the south-east corner of St Vincent, looking north along the windward coast. Inland, the topography is rugged, and often heavily vegetated, and rises towards the active volcano, the Soufriere of Sty Vincent, which is hidden under cloud at the top left of the picture.  The new airport runway, at Argyle, runs across the brown strip of land forming the eastern-most headland.

St Vincent is a volcanic island, and part of the arcuate chain of the Lesser Antilles volcanic arc. The active volcano on St Vincent is called the Soufrière; a name that describes its sulfurous nature, and shared by other volcanoes in the Antilles including the Soufrière Hills volcano (Montserrat), and the Soufrière of Guadeloupe.  While the geological record of past eruptions of St Vincent stretches back for hundreds of thousands of years, the historical record of known eruptions is short, but dramatic.

The first known explosive eruption of St Vincent was in March 1718. By all accounts this was a major eruption, preceded by an extended period of felt earthquakes. While there are no known first-hand descriptions of this eruption, a writer, thought to be Daniel Defoe, published an “An account of the Island of St. Vincent in the West Indies, and of its entire destruction on the 26th March last” in the Weekly Journal or Saturday’s Post of July 5th, 1718 (also known as Mist’s Journal), based on correspondence from ships that had been in the vicinity. This describes a short, but violent explosive eruption  “They saw in the night that terrible flash of fire, and .. heard innumerable clashes of thunder”, and the fallout of ash far downwind “In the afternoon they were surpriz’d with the falling of something upon them as thick as smoke but fine as dust, and yet solid as sand ; some ships had it nine inches, others a foot thick, upon their decks; the Island of Martenico [Martinique] is covered with it at about 7 to 9 inches thick; at Barbadoes it is frightful, even to St. Christophers it exceeded four inches.” Defoe’s account became well known when it was later included in a collection of his works (Romances and Narratives, Volume 15, edited by George Aitken and published in 1895/6). 

The first detailed account of the crater of the Soufrière dates to 1784 – when Alexander Anderson, then curator of the Botanic Gardens of St Vincent, wrote an account of  “The mountain of Morne Garou in the island of St Vincent and the volcano in its summit“. This letter was published in the Philosophical Transactions of the Royal Society, along with a fabulous plate showing the crater, partly filled with water and with a steaming dome (of what we now know to be lava) at its centre. In many respects, this view is remarkably similar to the state of the crater at the present day.

The next major eruption of St Vincent occurred in 1812, in an event which was captured dramatically both in written reports, and in a painting by JMW Turner (The eruption of the Souffrier Mountains, in the Island of St Vincent, at midnight on the 30th of April, 1812, from a sketch taken at the time by Hugh P. Keane). The observer who provided the sketch, Hugh Perry Keane, was a barrister and plantation owner; his diary of the eruption survives in an archive in Virginia, but not the sketch.

account of 1812 eruption


Description of the eruption of the Souffrier Mountain on Thursday night the 30th April 1812, in the island of Saint Vincent’. Extract from the Report from the Committee on Petition of Persons Interested in Estates in the Island of Saint Vincent, Parliamentary Papers of the House of Commons, Printed by Command, 7 May 1813, pp 182-193. The same description was published in The Times newspaper of 30 June 1812.

British Parliamentary Papers from 1813 contain a ‘Description of the eruption of the Souffrier Mountain on Thursday night the 30th April 1812, in the island of Saint Vincent’ which introduces the volcano and describes the precursory activity. This account had previously been published in The Times newspaper, and appears to be based on written testimonies from residents on the island that had been sent to the newspaper.

The Souffrier Mountain, the most northerly of the lofty chain running through the centre of this island .. had for some time past indicated much disquietude; and from the extraordinary frequency and violence of Earthquakes, which are calculated to have exceeded two hundred within the last year, portended some great movement or eruption..“. This account also provides a vivid and detailed description of the short-lived but violent eruption, and its immediate aftermath: “The birth of May dawned like the day of judgement. A chaotic gloom enveloped the mountain, and an impenetrable haze hung over the sea with black sluggish clouds of a sulphurous cast; the whole island was covered with .. cinders, scoria and broken masses of volcanic matter.

A petition from landowners across the island to the British Government outlined the extent of losses and damage from the eruption, explaining that parts of the island “have suffered in an extreme degree; the showers of volcanic matter .. having covered the whole surface of the ground [in that area] about ten inches deep;.. but most providentially, not many lives were lost.”

Nearly a century went by before the next eruption; a hugely destructive event that began in earnest on 7th May 19o2, just a day before the destruction of St Pierre on the nearby island of Martinique, following the eruption of Mont Pelée. The 1902 –  1903 eruptions of St Vincent resulted in a great loss of life (at least 1500), and severe economic impacts, all of which were widely documented in articles and reports at the time. As a result, we have a fantastic archive of primary observations, data and material to work with as we set out to investigate, retrospectively, the nature and consequences  of the 1902 eruption – a type of event which has occurred three times in the past 300 years.

Documentary evidence from this eruption includes the correspondence, reports and photographs from the wonderfully named Tempest Anderson, an opthalmologist, photographer and early volcano-tourist.  Anderson was rapidly commissioned to make a field visit to the island, which he published in early 1903. As this letter to the Royal Society attests he was a stickler for detail, and his accounts and photographic records from the time make for astonishing reading.

Letter from Tempest Anderson to the Assistant Secretary, Royal Society, from the Royal Society Archives.
Feb 15., 1903.
Dear Sir, with reference to the Plates for the Report on the Volcanic Eruptions in the West Indies which have been engraved by Collings from my negatives, I wish to inform you that Dr Flett and I have had great difficulty with Collings and have only at last with considerable perseverance been able to [over] get satisfactory proofs. As even now it is quite possible that some failures may occur when they are carefully printed I would be much obliged if you could arrange for printer pulls of all the plates be sent to me before the printing is finally proceeded with …’

Meanwhile, the details of the eruption and its effects are exhaustively recorded in Colonial Reports and Parliamentary Papers from the time.

Colonial Reports for 1902

Colonial Reports – Annual – for 1902-1903. St Vincent. ‘All minor events are eclipsed by the appalling eruption of the Soufrière volcano, which on 7th May awoke from its 90 years’ slumber to again hurl death and devastation over nearly one-third of the hapless Island of St Vincent‘, Edward J Cameron, Administrator.

After 1903, Soufrière St Vincent returned to a state of quiescence which wasn’t disturbed until 1971, when a remarkably quiet eruption built a new lava dome within the flooded crater of the volcano. This new activity, and the subsequent unrest on the nearby island of Guadeloupe in 1976, helped to stimulate the expansion of networks of instruments, including seismometers and tiltmeters, to monitor the volcano. This investment paid off quickly, with the rapid onset of new activity in 1979.

The 1979 eruptions began with only a very short period of unrest, starting with a strong local earthquake on April 12.  Eruptive activity began with a series of short-lived but violent explosions and that lofted a series of ash plumes, high into the sky on April 13, 1979; Good Friday. This heralded two weeks of vigorous activity that peaked with an 18 km high plume on April 17, and ended, with the cessation of measurable seismicity on April 29. After this, the eruption switched to the quiet extrusion of lava, slowly forming the dome that still sits in the crater today. The 1979 eruption caused much disruption, with 20,000 people evacuated to shelters, but no direct loss of life.

One of the goals of the workshop on St Vincent was to find out from the residents of St Vincent and neighbouring islands about the current awareness of volcanic risk, and risk communication. Participants included representatives of emergency management organisations both from St Vincent and the Caribbean region, as well as residents of St Vincent from all walks of life, including those with direct experience of the eruptions of the 1970’s, and people currently charged with reponsibilities across the spectrum of disaster management and response, both in the public and private sectors. This was a tremendous experience, and the STREVA team arel now working hard to analyse the results, develop new ideas and share understanding of how best to improve preparedness for future volcanic unrest and the response to future volcanic emergencies.

The Botanic Gardens of St Vincent and the Grenadines

17 Jan

The oldest Botanical Gardens in the western hemisphere lie on the outskirts of Kingstown, St Vincent, in the Windward isles of the West Indies – and what a gem they are. As the ironwork above the entrance declares, the gardens were founded in 1765.

The original ambition of Robert Melville, the then Governor in Chief of the Windward Isles, was to establish a horticultural research station for ‘the cultivation and improvement of many plants now growing wild and the importation of others from similar climates” which would ” be of great utility to the public and vastly improve the resources of the island”. The early years of the Botanical Garden saw the rapid establishment of cinnamon, nutmeg and mango trees, among others,  leading to awards from the newly formed Royal Society for the encouragement of Arts, Manufactures and Commerce, which was offering a number of medals and monetary prizes for the promotion of agriculture in the then colonies of the British Empire.

The Botanic Gardens flourished under the direction of its first two superintendents,  George Young (also Medical Officer for St Vincent) and later Alexander Anderson, a surgeon and botanist. Anderson was, among other things, responsible for the establishment of breadfruit on St Vincent (delivered by Captain William Bligh, formerly of HMS Bounty, and later HMS Providence – both ships designed for botanical missions). He also wrote an early account of a visit to the volcanic crater of Morne Garou (now called the Soufrière of St Vincent).

After 1819, the gardens fell into decline and were not reinstated until 1890.  In the latter years of the nineteenth century, the gardens were re-established under the curatorship of Henry Powell, to include a botanical station for experimenting on the development of new crops and new agricultural techniques, with experimental plots distributed around the island of St Vincent. By this stage, the production of two economically-significant crops of sugar and arrowroot were already in decline, and considerable efforts were made to develop the potential for Sea Island cotton growth on the islands. Scientific results from these experiments were reported in great detail annually, so there is a wonderful archive record of the subsequent impact of the devastating eruptions of the Soufrière of St Vincent in 1902-1903 on agriculture across St Vincent. The experiments on cotton growth also meant that the agriculturalists of the day were well prepared to diversify into this new crop following the eruption.

The Botanic Gardens remain under the jurisdiction of the Ministry of Agriculture of St Vincent and the Grenadines, and the legacy of its (nearly) 250 year history can be appreciated in the diversity of the mature trees and plants that can be enjoyed every day by visitors to the gardens.

Remote sensing of volcanoes and volcanic processes

8 Jan
Image

The spectacular front cover of the Geological Society of London Special Publication 380 – with many thanks to Elspeth Robertson and ESA for this SPOT5 image of Longonot volcano, Kenya.

A major goal of volcanological science is understand the processes that underlie volcanic activity, and to use this understanding to help to reduce volcanic risk. Advances in instruments and techniques mean that scientists can now measure many different aspects of the behaviour of  restless or active volcanoes, including seismicity (to detect magma movement at depth, for example); deformation (often reflecting pressure changes at depth); and emissions of heat and gas.  With the exception of seismicity, which requires sensitive instruments placed close to the volcano, many of these measurements can now be made remotely using instruments on board satellites or aircraft.

Remote-sensing techniques have transformed our capacity to detect, monitor and measure volcanic activity worldwide. In the past 35 years, applications have moved from the first satellite remote-sensing observations of the rise and spread of a volcanic plume and volcanic gases from an explosive volcanic eruption (the April 1979 eruption of the Soufriere of St Vincent in the Caribbean); to the current situation where constellations of satellites are used to provide routine monitoring of volcanic gas emissions, volcanic hotspots and volcano deformation. As well as dramatically improving our ability to monitor the progress of volcanic eruptions, these techniques also help us to understand better how volcanoes work by providing long-term data on what happens at volcanoes when they are not erupting; and by making it possible to compare the behaviour of different volcanoes in ways that are simply not possible from the ground, or with ground-based observations.

In a new Geological Society of London Special Publication, we have brought together a selection of papers that give a broad perspective of the current state of the art in the remote sensing of volcanoes and volcanic processes. The 14 papers in the volume focus on the observation, modelling and interpretation of satellite-remote sensing of volcanoes: from surface deformation, to thermal anomalies, gas fluxes and eruptive plumes. Many of the papers take a broad perspective, reviewing current techniques and applications, or demonstrating the potential to investigate volcano behaviour and volcanic activity at regional to global scales.  Papers in the volume also show the ways in which people are now trying to go from these observations to a deeper understanding of underlying processes, by integrating observations with theoretical models and computer simulations of volcano behaviour; and then to use these insights to advance the potential for eruption forecasting. We hope that this Special Publication will find a wide and appreciative audience out there!

Earth Observation (EO) techniques now allow the detection and analysis of a spectrum of different aspects of volcano behaviour at both non-erupting and  erupting volcanoes. From the introduction to the Geological Society Special Publication 380 (Pyle et al., 2013).  The seismic event rate trace is schematic, but based on observations at Mt St Helens in March – May 1980. 

 

Editing a volume of this scale requires a lot of support from a lot of people. On behalf  of the editors (Tamsin Mather, Juliet Biggs and myself), we would like to thank the authors of all of the contributions for their hard work and for entrusting their manuscripts with us; we would like to thank the very many reviewers who selflessly gave up their time to provide the feedback and constructive criticism of the papers that is the key part of the peer-review process; and we would also like to thank the staff of the Geological Society’s Publishing House, and in particular Angharad Hills, Tamzin Anderson and Hannah Sime, who shepherded this v0lume from start to finish, and who have turned our initial idea into such a wonderful physical volume. Finally, and on behalf of all of the authors, we would like to acknowledge the many individuals, institutions and agencies who have provided the facilities, funding, imagery and datasets which have underpinned all of this work.
