Earthquake Swarms Hit Mount St. Helens
  • Small Series of Tremors hit Mount St. Helens

A small series of tremors hit Mount St. Helens recently which struck fear in the hearts of the surrounding inhabitants.

During the past two months, over 130 small earthquakes have struck Mt. Saint Helens. While at present there are no signs that it will erupt, some such scenario could occur in the future.

The volcano is still dormant yet it could erupt any time. The odd gaseous stuff that normally surrounds it is not to be seen. Also magma is non-existent. Yet the volcano is sort of restarting itself in a “silent yet terrible in storm” manner.  

Mount St. Helens is located in Washington State. The earthquakes clocked in at 0.5 or 1.3 on the Richter Scale. Their epicenter is 1.2 to four miles beneath the earth’s surface, according to USGS. Such earthquakes are very small in their incidence.

They can hardly be felt. However, magnitude is not an issue. It is the great frequency of the earthquakes that has the researchers all riled up. These are not ordinary earthquakes.

They show symptoms of a lot of activity brewing deep down inside the earth. Since March 14th, they have increased in frequency. There has been a rate of 40 small earthquakes per weekly basis.  

There is a re-pressurization of magma going on inside the volcano. Tha magma is collecting steam to go ahead at full tilt when the time is right. Yet this time could be years away.

Similar trends have been seen in the 1990s and in 2013 and 2014. Back in 1980, Mount St. Helens blew its top and flung ash and lava from its center. 57 people died as a result of the explosion.

The volcanic matter reached 1000 feet up in the air. Also nearby forests were consumed by flames and the frozen snow from mountain tops melted causing floods as a side effect. 

Ever since that day, Mount St. Helens has remained one of the most closely monitored volcano on the surface of the earth. With these new series of earthquakes swarming the volcano, trouble seems to be brewing.

Volcanoes can be metaphorically compared to sores on the skin of a person. The cracks which are appearing in Mount St. Helens are the main cause of the earthquakes. So far no dramatic event has transpired, yet anything could happen so we should expect the unexpected.
