Mount St Helens starts rumbling again

Mt St Helens | Image: National Geographic/AP After a three year period of being dormant, Mount St. Helens is again showing signs of seismic activity, although scientists say there’s absolutely nothing to worry about – yet.

Several small tremors (just under 3.0 magnitude) were recorded, as well as steam coming from the top of the volcano, which is well remembered for its cataclysmic eruption in 1980 (video), which killed 57 people and flattened 230 square miles of forest.

So what’s causing this new activity? Scientists believe it is because the lava under the volcano is shifting around, possibly squeezing water out and causing slight tremors. Will it erupt again? It will without doubt one day, but it is still highly unlikely at the moment.
