Costa Rica News – The tremor of 5.5 degrees from November 30th was the strongest of 2016.
Experts question whether magma could have activated it. Scientists discovered that the origin was in a previously unknown fault.

The fault is right in the middle of the volcanoes Irazú and Turrialba, five kilometers from each.
It’s called Liebres because it crosses a farm with that same name in Capellades, Cartago.
The tremor was only a kilometer deeper than sea level.
The cracks that cut volcanic masses ranged from 4 to 12 kilometers in length and are capable of generating earthquakes with magnitudes
