Unexpected magma chamber grows under Mediterranean underwater volcano Colombo

(ORDO NEWS) — Using a new volcano imaging technique that captures high-resolution images of seismic wave properties, researchers have discovered a large, previously undiscovered, mobile magma pool beneath Columbo, an active underwater volcano near Santorini, Greece.

The presence of a magma chamber increases the likelihood of a future eruption, prompting researchers to recommend the establishment of real-time hazard monitoring stations near other active submarine volcanoes to improve the likelihood of an eruption.

Almost four hundred years ago, in 1650 BC, Colombo erupted, killing 70 people on Santorini. This eruption was triggered by growing reservoirs of magma beneath Colombo’s surface. The researchers now claim that the molten rock in the chamber reaches a similar volume.
