On this day twenty-eight years ago, 18 May 1980, Mount St Helens in Washington State, USA, erupted in the most destructive and deadly volcanic eruption in United States history. Fifty-seven people were killed, over one billion dollars of economic damage done, and vast stretches of landscape laid waste by this cataclysmic event.

The Alaska Volcano Observatory 1988-2008 23 April 2008

The Alaska Volcano Observatory is currently marking its twentieth anniversary, and a profile of the AVO appears today at AlaskaReport.com. Among other things it explains what a difference technology has made to volcano monitoring and hazard mitigation since the AVO was set up in 1988.

The last two decades have seen the development of satellite sensors that allow people to check for volcano hotspots several times a day, precise GPS receivers that enable scientists to watch volcanoes inflate and deflate, infrasound sensors that record sudden changes in air pressure during explosive eruptions, and the advent of a helpful tool called the Internet.

The article is written by Ned Rozell, a science writer at the University of Alaska Fairbanks Geophysical Institute (one of the partners behind the AVO).

Capelinhos 1957-8: fifty years on 12 April 2008

Fifty years ago, between September 1957 and October 1958, a dramatic submarine eruption took place on Fayal island in the Azores. Fayal itself is a large stratovolcano with a wide caldera; the eruption took place on the west flank of the volcano, beginning at a point about 1 kilometre west of what was then the westernmost point of the island, and created the volcanic cone of Capelhinos which began as an island and is now a peninsula.

The eruption was one of the most closely-studied in the history of volcanology. It was also highly disruptive for the island’s population: vast amounts of ash were erupted, agriculture was ruined, hundreds of homes destroyed or rendered uninhabitable, and the economy of the island severely damaged. More than 2000 people were evacuated, many to begin new lives in the United States, where a sizeable Portuguese-American population traces its origins to the eruption and the subsequent relief effort today.

The story of Capelinhos is thus not only a scientific story but a profoundly human one as well. The fiftieth anniversary of the eruption is being marked in the Azores and mainland Portugal, and in the United States, with events and publications that reflect all aspects of this historic event.

On 10 March 1908 members of the British Imperial Antarctic Expedition (also known as the Nimrod Expedition) climbed the active Antarctic volcano Mount Erebus on Ross Island, the first people to make the ascent to the crater rim. The 100th anniversary of this achievement is being marked today at the Mount Erebus Volcano Observatory, which is run by New Mexico Tech at the very un-Antarctic location of Socorro, New Mexico.
