Health Editor’s Note: After spending a few days in Iceland, exploring its geology, volcanic history, current geothermal uses, etc. the report of an active volcano is very interesting and I am wondering if this eruption could cause issues with plane travel as the Eyjafjallajökull volcano of Iceland, which erupted in 2010, did…Carol 

Astronauts Capture Stunning Image of Volcano Erupting for the First Time in 95 Years

By Brigit Katz-Smithsonian.com

Raikoke, an uninhabited volcanic island in the northwest Pacific, last erupted in 1924. It then went silent for nearly 100 years, until, on June 22, Raikoke spewed forth a blast of ash and volcanic glass so powerful it could be seen from space. And fortunately, astronauts on board the International Space Station were there to capture the moment.

A dramatic photo released by NASA shows the volcano’s plume shooting up over the clouds. It forms a narrow column that spreads into what is known as the “umbrella region”—the area where the density of the plume and that of the surrounding atmosphere equalizes, causing the plume to stop rising. You can also see a ring of clouds around the column, possibly the result of water vapor condensation or the “interaction between magma and seawater,” says Simon Carn, a volcanologist at Michigan Tech. “Raikoke is a small island and flows likely entered the water,” says Carn.
