Eruption threat means all 11,000 people of Ambae in the Pacific need to leave – and with sparse official help, they are getting off any way they can

October 1, 2017 — Vanuatu is no stranger to the rumblings, shakings, flood waters and wrecking winds of natural disaster. The south Pacific island nation was rated the most at-risk country in the Continue reading Planes, ships, barges: the DIY evacuation of Vanuatu’s volcano island

Drone Peers into Open Volcanic Vents

During a May 2016 pilot project, the authors sent unmanned aerial vehicles where humans couldn’t go to capture images and gather data on the locations and characteristics of Stromboli’s craters and vents.

An unmanned aerial vehicle provided the high-resolution data that allowed scientists to construct their first detailed map of erupting vents at Stromboli, one of the world’s most active volcanoes

September 27, 2017 — Volcanoes that erupt frequently give researchers special opportunities to make repeated high-resolution observations of rapid eruption processes. At explosive volcanoes like Stromboli, situated just off the southwestern coast of Italy, “normal” explosive eruptions take place every few minutes to tens of minutes. However, the rainout of hot volcanic bombs, some as large as a meter across, makes it hazardous for scientists and their instruments to get close enough to Stromboli’s active vents to collect some forms of essential data.
