Scientists Observed Rare Volcanic Event

Scientists observed a rare volcanic event for the first time. The 2014 eruption of the Bardarbunga volcano was the strongest Europe experienced in over two centuries. Several magnitude 5 earthquakes shook the Icelandic volcano, releasing magma from its core.

As Bardarbunga erupted, the center sank over 3 feet a day for three weeks. A 42 square mile caldera formed. these rare volcanic craters only occur a few time per century worldwide. This was the first scientists observed in detail to figure out how they form. The researchers now think the flow of magma is what causes Caldera formation. 

Bardarbunga erupted for 182 days. Its magma chambers lies beneath Europe's largest glacier, Vatnajokull. The nce fiery caldera is now filled with ice.
