Mount Adams, which is the largest active volcano in Washington , has had a record-breaking spike in the amount of earthquakes that have been happening in the area.
The US Geological Survey (USGS) has revealed six occurred in September alone – there’s usually just one every two-to-three years, reports IFL Science .
The six registered had magnitudes between 0.9 and 2.0 which were picked up by a seismic station around 11 kilometres away from its summit.
The location and depth of the earthquakes are not exactly known.
A statement from USGS said: “This represents the most earthquakes located at Mount Adams in a month since monitoring began in 1982.”
The USGS adds there isn’t anything to worry about despite Mount Adams being ranked as a ‘high-threat’ volcano.
That’s because it’s a quiet one, with it not having erupted in at least the last 3,800 years, and none of the earthquakes have been strong enough to be felt on the surface nor indicate an eruption is imminent.
