Scientists have warned that some of the world’s most dangerous volcanoes are understudied, making it harder to predict if or when they may erupt.
The Cascade arc of volcanoes stretches from northern California in the US to British Columbia in Canada. More than a dozen volcanoes are found along the iconic range, but a new study has revealed vital information about them is missing.
Predicting eruptions is still far from an exact science, with different volcanoes displaying different behaviours before erupting – and in some cases, giving very little warning.
Others, as in the case of the ongoing activity in Iceland, can rumble on for quite some time.
One key aspect to predicting eruptions is the volume, location and flow of magma beneath the volcano, something scientists argue is lacking in the Cascade region.
