New Volcano Might Form Due to Frequent Earthquake Swarm in Mexico

Major earthquakes - and massive volcanoes - are nothing new in Mexico. In reality, on the 32nd anniversary of an even more destructive quake, a huge quake-damaged town across the nation (including the capital, Mexico City) in 2017.

Another UNAM researcher, Denis Xavier Francois Legrand, acknowledged that while an earthquake swarm is an essential indicator of a new volcano's growth, it is not the only one. Experts are also looking for deformation in the Earth's crust that would allow a volcano to burst through below, and magma flows upward rather than sideways.

"We believe these [earthquake] swarms are linked to magma flow, although magma does not always reach the surface. These swarms happened in 1997, 1999, and 2006, but no magma reached the Earth's surface. Perhaps something similar is occurring today, but it's critical to keep an eye on [magma movements]," Francois said at a virtual news conference on Tuesday.
