One year

I’ve delayed writing about my involvement in last summer’s Kilauea eruption for a number of reasons. One is because I wanted to wait until the USGS has had a chance to publish the preliminaries of the eruption; others are more personal, involving my experience working with the communities affected and the people responding to the eruption. But now that the one-year anniversary of the start of the eruption has come …

New automated volcano warning system forecasts imminent eruptions

Scientists have developed an automated early warning system for volcanic eruptions, according to a new study. The new system helped government officials warn the public of impending eruptions in Italy and could potentially do the same around the globe, according to the study’s authors. The new research details the new system that monitors volcanic noises and automatically alerts officials if an eruption is imminent. The study’s authors tested this system over a period of eight years on Mount Etna, a volcano on the island of Sicily. Using the new system, the Italian government activated an emergency plan about one hour prior to an eruption for the first time in late 2015.

Rehearsing for eruptions

In the past few weeks, I’ve had the opportunity to help run several “tabletop” exercises with the USGS and our partners where we walk through a timeline of what might happen during a volcanic eruption, and ask participants to make decisions about how they would need to respond and work together. I find them both fascinating and exhausting.

Ísland: Floods

When you bring together volcanoes and ice – as many places in Iceland do – you get floods. Specifically, they’re called jökulhlaups, which literally means “glacier run” but in reality means a glacial outburst flood. Originally the term was used for subglacial outburst floods from Vatnajökull ice cap, which covers the Grímsvötn and Öræfajökull volcanoes, but it’s come to mean any large, abrupt release of water from under a glacier or from a lake at the glacier front.

Volcano pressure guns show how rocks spew and eruptions ensue

The vinegar volcano is a stale science experiment. But Italian geologist Valeria Cigala takes the tired demonstration to a violent new level…
