OPINION (Express) – During the month of April, a total of 63 earthquakes struck around the Wyoming based supervolcano. All of the tremors were relatively small, with the largest registering at 2.6 on the Richter scale, hitting on April 29. But experts have warned that it is not necessarily about the strength of an earthquake around a volcano, but more the quantity of them. Some scientists believe that tremors around a volcano could be a sign that it might blow. Portland State University Geology Professor Emeritus Scott Burns said a spate



of small tremors around a volcano usually signifies that magma and gasses beneath the surface are beginning to navigate their exit. He said: “If you get swarms under a working volcano, the working hypothesis is that magma is moving up underneath there.” However, others disagree about whether an earthquake swarm near a volcano could be a sign of things to come. Jamie Farrell at the University of Utah in Salt Lake City, believes this is just part of the natural cycle for Yellowstone volcano, saying: “Earthquake swarms are fairly common in Yellowstone. “There is no indication that this swarm is related to magma moving through the shallow crust.” READ MORE
