Saturday/ 44 years ago 🌋

Today marks the 44th anniversary of the 1980 Mt St Helens eruption.

‘We know that Mount St. Helens is the volcano in the Cascades most likely to erupt again in our lifetimes. It is likely that the types, frequencies, and magnitudes of past activity will be repeated in the future. However, neither a large debris avalanche nor a major lateral blast like those of May 18, 1980 is likely now that a deep crater has formed’.
