The Costa Rica News (TCRN) – According to the Earthquake Engineering Laboratory (LIS) at the University of Costa Rica (UCR), recorded seismic activity at the epicenter of the earthquake on September 5 of last year, in Nosara, has been less than expected considering the quake had a magnitude of 7.6.
Aaron Moya, LIS seismologist, said the number of aftershocks above 5 degrees have been low compared with other similar events in other countries in the region.
“It is low in the sense that for a 7.6 as we had less than what has been observed in other countries, with only about five small shocks, “said Moya.
The seismologist said the earthquake was very large, especially in an area where for over 50 years there was a low rate of earthquakes. October 24th was the anniversary of the strongest aftershock, when there was a 6.3 earthquake.
“In the center of the country the activity is large while in the Northern Zone it has always been low. This can mean that the movement is aseismic or otherwise it may be that the energy has been accumulating and so strong earthquakes will happen,” said Moya.
