After the strong earthquake of 5.8 degrees on the border between Costa Rica and Panama, the National Seismological Network (RSN) reported – at least – 2 replicas of considerable intensity after the main telluric movement.
One of them was registered at 6:36 p.m. with a magnitude of 3.9. It had a depth of 15 kilometers. The epicenter was 46 kilometers east of Sabalito de Coto Brus, that is, very close to where the strongest movement occurred.
The other replica occurred at 7:01 p.m., with a magnitude 2.7 degrees. The epicenter was located 40 kilometers east of Sabalito. In the same place as the earthquake that occurred at 5:54 p.m.
Although the epicenter was in Panamanian territory, the tremor was perceived in much of the Costa Rican territory.
Its origin was a local fault. Precisely, the border area between Costa Rica and Panama is characterized by a constant seismic activity.
