Volcano Top Trumps: the Online Game

9 Oct


After some months of testing and refining, a free-t0-use online version of Volcanoes Top Trumps has been launched by Winning Moves. This should greatly extend the reach of Volcanoes Top Trumps – which is a fun and educational game about volcanoes that has spun off from the NERC - ESRC funded project ‘STREVA‘ – Strengthening Resilience in Volcanic Areas. Why not play the online game, and then let us know what you think of it!


Volcanoes Top Trumps was created by scientists at the University of East Anglia, the University of Plymouth and the University of Oxford.

There’s (volcanic) dust in the archives

14 Aug From the BGS archives

There’s not much that beats the thrill of discovery.. particularly when it turns up in your own backyard.  This summer, I have been on the hunt for records and reports of the 1902 eruptions of St Vincent, a lush volcanic island in the Eastern Caribbean. There are indeed many reports from this eruption, carefully documented in official records from the time. But, more surprisingly, there are samples – and many of them in the UK: packets, vials and boxes of ash; chunks of rock and more, in museum collections and archives in both the Natural History Museum, and at the British Geological Survey. Here is just a snapshot of some of the incredible samples from the British Geological Survey Archives.

From the BGS archives

Four vials of volcanic ash – all collected on Barbados. The smallest vial is of ash from the 1812 eruption of St Vincent. The three other vials are samples of ash that fell on Barbados during eruptions between May 1902 and March 1903.

Along with the samples are the original envelopes in which they were sent, and handwritten notes documenting the sample: priceless tools, when you want to look back at an eruption that took place over 100 years ago.

1902 Barbados ash

1902 Barbados ash sample sent to Horace Woodward, who was in charge of the Geological Survey’s office in Jermyn Street, London, at that time – which included the Museum of Practical Geology. Memo reads ‘Dust from Mt Soufriere St Vincent, collected on the deck of the SS ‘Statia’ lying at Barbados, 90 miles distant, travelling against a strong S E wind and covering everything to the depth of 5 inches. 1903′.

Some of these samples are timed and dated, and can be linked to particular phases of the eruption. Here is one example – of the ash that fell during the opening stages of the eruption on Barbados.

First hour

‘Volcanic dust collected at Barbados during the night May 7-8 1902. This spec. fell during the first hour’. Collected by WG Freeman, a botanist at the Imperial Department of Agriculture for the West Indies in Barbados.

Other samples can be used to map the distribution of ash and coarser samples that fell across St Vincent – here’s an example of a ‘gravel’ grade sample from Rosebank on St Vincent.

1902 ash

1902 tephra sample collected on St Vincent by  Henry Powell, Curator of the Botanic Station on St Vincent. ‘Sample of volcanic sand which fell at Rosebank (Leeward) on night of 3rd and morning of 4th Sept. 1902′

Among the most amazing discoveries, are examples of damage to economically valuable plants – this one, a sample of Breadfruit leaf that was damaged during the latter stages of the eruption in March 1903.


‘A leaf of the Bread Fruit Tree (Artocarpus incisa) gathered in St Vincent about 12 miles from the Soufriere and showing perforation caused by volcanic stones etc.’ Collected by WG Freeman in 1903.

Together, these sorts of samples will allow us to go back and investigate what was actually happening during the eruption, in a way that is rarely possible, even for modern events.

Summer Reading – H is for Hawk

11 Aug

Much of my time is consumed with reading, but it is almost always for a purpose: essays, assignments, proposals, drafts of papers, re-drafts of papers, papers for classes, for review..  This almost always means reading fast, with a goal: to measure, assess, hone, distil, critique and rewrite.  Often, it means hacking through tangled and cumbersome layers of scientific prose, to reveal the central narrative.

Then, for in a few days in midsummer, I get the chance to rediscover reading for pleasure: immersion in a book that grabs hold of your imagination and translates you to another place and another time. This year, my summer reading has got off to a cracking start with ‘H is for Hawk’.

Helen Macdonald's H is for Hawk, alongside TH White's Goshawk.

Helen Macdonald’s ‘H is for Hawk’, alongside TH White’s ‘The Goshawk’


‘H is for Hawk’, written by Helen Macdonald and published by Jonathan Cape, is a dizzying, dazzling read that defies its rather sober classification (‘Nature Writing/Biography’). The book weaves together a deeply personal story of grief and loss, with the rediscovery of life lived through the training of a young goshawk. In places, the staccato text crunches like the twigs strewn across a forest floor; in others, it soars like the circling hawk, magnificent, alert to the slightest movements below. It contains some wonderful writing on nature, capturing the very essence of the countryside in just a few words, alongside some moving reflections on bereavement and the way that death changes in a moment the lives of the living, and our relationships with what was present and is now past. In parallel, and wrapped up closely with the training of her young goshawk, Helen Macdonald explores the life and writing of TH White, a teacher and writer of Arthurian novels who wrote of his own struggle to train a goshawk in the 1930’s.  The result is a book that works on several levels, and would reward re-reading: a beautiful and captivating read.

H is for Hawk by Helen Macdonald, published by Jonathan Cape, 2014. ISBN 9780224097000

An eyewitness account of the 1812 eruption of the Soufrière of St Vincent

The Soufrière of St Vincent erupted dramatically in early 1812, in the first eruption of the volcano that was documented in detail at the time. Like the eruption of 1718, this was a fairly short-lived explosive eruption that was over in a few days. And, as with the 1718 eruption, it followed a period of several of months during which there were earthquakes large enough to be felt by the local populations.

In 1812, St Vincent was a British colony, and sugar was the major export: in fact, St Vincent ranked second only to Jamaica in terms of sugar production at that time.  The total population of the island in 1812 was around 26,000, 90% of whom were…

Reblogging a post of mine from LondonVolcano

One of the goals of the STREVA project is to try and learn more about the effects that volcanic eruptions have on people’s lives and livelihoods by examining what has happened in the past. This throws up some interesting challenges – the geological record of past eruptions may not be preserved, while the written or oral records of past eruptions will usually be far from dispassionate or accurate. But in some cases, these written records may be all that are left, and the fun is then to try and work out what may, and what may not be, plausible.

We have chosen St Vincent in the Eastern Caribbean as the model for London Volcano because it has a rich record of historical eruptions, many of which have been documented in one way or another. The first of these was an eruption in 1718.

Looking ahead to the London Volcano and Universities UK Week, 2014

3 Jun


Over at http://LondonVolcano.com we are getting ready for Universities UK Week, and the launch of our ‘live’ volcano in front of London’s Natural History Museum

Originally posted on londonvolcano:

London Volcano will sit, resplendant, on the west lawn of London’s Natural History Museum for Universities UK Week, from 9 – 13 June; with a special ‘late night opening’ on June 11th. It will be the backdrop to a week-long programme of activities that will explore what it is like to live near an active and erupting volcano; to think about what we can learn about living with volcanoes, and recovering from the consequences of volcanic eruptions; and to see how modern technologies allow us to probe the inner workings of volcanoes from a safe distance.

Friday Field Photo – St Vincent, 1902

30 May
Roseau Dry River, St Vincent, 1902. Photo by Tempest Anderson, from Volcanic Studies.

Roseau Dry River, St Vincent, 1902. Photo by Tempest Anderson, published in his book  Volcanic Studies in Many Lands (1903).

Today’s field photo is by Tempest Anderson, of the ‘Roseau Dry River flowing with Boiling Mud’, a picture taken in the aftermath of the May 1902 eruptions of the Soufrière of St Vincent.  The full published caption explains the origins of this boiling mud – a phenomenon we now call a lahar:

This is a small stream in the Wallibu Basin. When the water undermines the banks and the hot ashes fall into the river, the stream is often dammed up, and the giving way of the obstruction is associated with a great discharge of boiling mud. In one of our ascents of the Soufriere, we had crossed the Rozeau Dry River without difficulty in the morning when the weather was fine, but heavy rain had fallen before our return in the afternoon, and the river was full of boiling mud, coming in gushes, as shown in the picture. After some trouble our men cut down two trees which had been killed by the eruptions, and made a bridge by which we crossed. The banks show the characteristic erosion by the rain rills.’

 Lahars are a very common feature at volcanoes, and they may often continue to be triggered by strong rainfall events for months or years after the eruptive activity has ceased.

 Tempest Anderson was an opthalmologist by profession, and also an inveterate traveller and photographer. He accompanied  John Flett to the Caribbean to document the eruptions on St Vincent and Martinique, in 1902, and a selection of his photographs can be found on the website of the Yorkshire Museum. The Soufrière of St Vincent is the centrepiece of the London Volcano project, which runs from 9-13 June.
