lava & magma

Photo of Icelandic Meteorological Office seismologist Kristín Jónsdóttir in the foreground, with erupting Fagradalsfjall in the background. As bright orange lava spills out of the small crater and flows behind her, eerie orange-tinged smoke billows into the air. The ground of solidified black basalt glows red.

Understanding Where and How Magma is Stored

by M. Pistolesi 17 May 202112 October 2021

Gravity measurements reveal depth and storage conditions of rhyolitic magma reservoirs beneath the Laguna del Maule volcanic field in Chile.

A large magma furnace pours a mixture of silicate and metallic lava onto a flat surface, with a pool of semicooled lava flowing. The lava is black, orange, yellow, and silver.
