A “swarm” of 130 earthquakes have trembled beneath Mount St Helens in the past eight weeks, seismologists have revealed.
The US Geological Survey (USGS) said the series of small quakes showed “the volcano is still very much alive”.
Although there are no signs of an imminent eruption, the volcano – 95 miles south of Seattle – is recharging, the seismologists have said.
There are no unusual gases reported, and no signs that the magma – the molten rock beneath the surface of the Earth, is expanding.
