Is the Ring of Fire Becoming More Active?
Costa Rican scientists are keeping an eye on Turrialba Volcano, on the Caribbean-slope, where thousands of small earthquakes have occurred over the past couple of days, according to experts from the Volcanological and Seismological Observatory of Costa Rica (OVSICORI) based at Universidad Nacional (UNA) in Heredia, north of San José.
The volcano, located in the community by the same name, recently registered more than 2,000 mini-earthquakes too faint to be felt by residents.
This seismic activity is characterized by its low frequencies and it is associated with an intense flux of gas and steam through volcanic channels, said a statement from OVSICORI.
Experts, who continue to study the volcano, believe it's possible it could experience a mild eruption, spewing sediment and materials accumulated in its crater, not lava.
Turrialba is an active volcano that last erupted lava in 1866, according to OVSICORI.
