'Highway from hell' fueled Costa Rican volcano

If some volcanoes operate on geologic timescales, Costa Rica's IrazĂș had something of a short fuse. In a new study in the journal Nature, scientists suggest that the 1960s eruption of Costa Rica's largest stratovolcano was ...

The brief but violent life of monogenetic volcanoes

A new study in the journal Geology is shedding light on the brief but violent lives of maar-diatreme volcanoes, which erupt when magma and water meet in an explosive marriage below the surface of the earth.

Tenerife island landscape reveals explosive past

Volcanologists from the University of Leicester have uncovered one of the world's best-preserved accessible examples of a monstrous landslide that followed a huge volcanic eruption on the Canarian island of Tenerife.

3D-Model mimics volcanic explosions

(PhysOrg.com) -- A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones ...

Scientists move closer to predicting volcano hazard

UK and Russian scientists say they are a step closer to predicting how dangerous a volcano is after developing a method that lets them figure out how individual volcanoes are 'plumbed'.

Scientists discover nanodiamonds in Greenland ice

(PhysOrg.com) -- University of Maine volcanologist Andrei Kurbatov and glaciologist Paul Mayewski, along with 21 other scientists, coauthored a scientific paper released late last month that details the discovery of a layer ...

Off the shelf maps help mitigate volcanic hazards

(PhysOrg.com) -- When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards managers. ...
