Costa Rica suffered yesterday, at 8:42 a. m., the second largest earthquake in its history.
However, despite the collective panic and damage that emerged with the passing hours, the impact of the phenomenon seems to be moderate when compared with the power of a 7.6-magnitude earthquake.
Last night, in a press conference, the president of the Republic, Laura Chinchilla quietly affirmed that the quake originated 20 kilometers south of Samara in Nicoya, Guanacaste, left no fatalities or serious injuries.
Hours earlier the Red Cross reported the death of a 50 year old woman inPhiladelphia Carrillo, from a heart attack, but denied that the death was related to the quake.
Chinchilla said that between four and five roads were affected by the quake, butsaid that no community was isolated because there are alternate routes.
The worst affected route is the one that communicates Zarcero with San Carlos, where a landslide will prevent the passage of vehicles for at least three weeks.
She also said that Monsignor Sanabria Hospital, Puntarenas, was evacuated for submission to a detailed review.
Meanwhile, Irene Campos, Minister of Housing, said yesterday that about 100 homes suffered some kind of involvement in the Nicoya Peninsula, Valverde Vega and Naranjo. Scores of engineers will visit the homes from today to assess the impact.
According to the National Seismological Network (RSN), this movement shares the position with the 7.6 magnitude earthquake that occurred in San Estanislao(Carthage) on May 7, 1822.
In the first place is the Limon earthquake, which occurred on April 22, 1991,which had a magnitude of 7.7 degrees Mw.
This movement caused a total of 48 deaths in Costa Rica and 79 in Panama.
The Volcanological and Seismological Observatory of Costa Rica (OVSICORI)explained that the origin of the movement yesterday was by subduction of theCocos plate under the Caribbean plate. It had a depth between 15 and 40kilometers, which is seen as superficial,
The release of energy caused the Nicoya Peninsula to rise one meter. Last night, at 9:30 p. m., the OVSICORI had reported a total of 330 aftershocks.
