The Botanic Gardens of St Vincent and the Grenadines

The Botanic Gardens of St Vincent and the Grenadines

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 …[Read More]

Remote sensing of volcanoes and volcanic processes

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, …[Read More]

Friday Field Photo: Mocho Choshuenco volcano, Chile

Early morning view of the volcanic cones of Mocho (left) and Choshuenco (right) in the Chilean Lake District. View from the outskirts of the Reserva Huilo Huilo. Mocho is thought to be the source of many of the post-glacial and younger eruptions from this volcano, including the two known historical eruptions in 1864 and 1937.

Volcanoes Under the Ice

A fascinating story has emerged this week from a paper in Nature Geoscience by Amanda Lough and co-workers (Lough et al., 2013), on the discovery of a new volcano deep beneath the ice of the Western Antarctic Ice Sheet (WAIS).  The discovery is partly a story of scientists looking in a place where no-one had looked before; …[Read More]

Friday Field Photos: Eruptions at Lokon-Empung volcano, Indonesia

Friday Field Photos: Eruptions at Lokon-Empung volcano, Indonesia

This week I am at a workshop near the twin-peaked volcano Lokon-Empung, in Sulawesi, Indonesia. True to form (it is the most active volcano in Sulawesi), Lokon has been rather active, with fairly frequent small explosions forming some small but dramatic ash plumes. The active vent is not at the summits of either Lokon, or …[Read More]

One year of volcanicdegassing

One year of volcanicdegassing

One year has passed since I first wrote a post for this occasional blog. Now, 12 months, 22 posts and 7500 page views later, here’s a quick look back. For me, this has been a way of using some of my back catalogue of field photographs, of fleshing out a bit of context around papers …[Read More]

August Anniversaries: the eruption of Krakatoa

August 27th marks the anniversary of the culmination of the great eruption of Krakatoa (or Krakatau) in Indonesia in 1883. This devastating eruption has become the archetype of a volcanic catastrophe, even though it was a geologically modest example of a ‘caldera forming’ event. The eruption of Krakatoa quickly made the headlines around the world, in …[Read More]

Timelapse volcanoes in Google’s Earth Engine

With the marvels of technology and the generosity of Google and NASA, we can now sit back and watch the back catalogue of volcanic eruptions using the magnificent Google Earth Timelapse of Landsat images. Here are just a few that I have picked out.. Enjoy, and do send more suggestions! Anatahan, Marianas, erupted in 2005. …[Read More]
