In 2014, scientists set off 23 blasts to uncover magma hidden beneath Mount St Helens

In a groundbreaking study, researchers utilized controlled explosions paired with seismic technology to investigate Mount St. Helens’ subterranean magma systems. They discovered a magma-reservoir located between four to fifteen kilometers deep. This extensive analysis employed numerous instruments to track seismic waves within the volcano, yielding vital knowledge about magma movements. Such understanding is instrumental in forecasting volcanic activity and potential eruptions.
