[Rockhounds] Hawaii’s surprise volcanic eruption: Lessons from Kilauea 2018

[Kreigh Tomaszewski]

In 2018, Hawaii's most active volcano took scientists by suprise. Lava
started spewing out not from the summit, but 50km away on the lower slopes
of the volcano. This unexpected eruption destroyed farmland, roads and over
700 homes. Since then, volcanologists have been piecing together the events
that triggered it. Using GPS trackers, high-speed cameras, chemical
analysis and more, researchers have learnt what happens when volcanic
craters collapse and how magma can move not just vertically but
horizontally underneath a volcano. These insights help us to understand
other similar volcanoes in Iceland, Italy and La Reunion. The hope is that
next time Kilauea or one of these other volcanoes erupts, we will be better
prepared.
