More than 4,000 earthquakes took place in 2014 in Costa Rica, but only 122 were strong enough to be felt by humans, said the Observatorio Vulcanológico y Sismológico at Universidad Nacional in Heredia.
Three of the stronger quakes were not even in Costa Rica, the Observatorio noted. These were the June 16 quake with a magnitude of 5.6 that had its epicenter at San Andrés island in the Caribbean, the Sept. 16 5.2-magnitude quake in Panamá and the Oct. 13 quake in El Salvador. That one was estimated at 7.3 magnitude.
There were a flurry of quakes in the Central Valley. The most notable, according to the Observatorio, was a 4.2-magnitude event July 24 in Guácima de Alajuela, one July 25 near Cartago Centro that registered a magnitude of 4.5 and a Nov. 1 event in Desamparados that had a magnitude of 4.2. Although these were relatively modest earthquakes, the Observatorio said that because they took
place in populated areas, there was widespread concern.
The annual report said that the total number of quakes in 2014 in and around Costa Rica were 5,986, significantly lower than the 2014 total of 7,439, said the Observatorio. In 2014 there were 155 quakes that were felt by humans, it noted.
