A 4.7 to 5.0 magnitude quake took place Tuesday morning in the center of the country.
The Laboratorio de Ingenieria Sismica estimated the location of the epicenter at about 2.8 kilometers east southeast of Buenavista de San Carlos and about 10.4 kilometers north northwest of Zarcero. The quake sent moderate tremors from Puntarenas to Cartago and from Sarapiquí south to San Isidro de El General, said the Laboratorio, which is based at the Universidad de Costa Rica. Sensors registered the quake at 10:11 a.m.
The Observatorio Vulcanológico y Sismológico at Univrsidad Nacional estimated the magnitude at 5.0. The Laboratorio said 4.7
The Laboratorio said that the quake was felt strongest in Jacó and in Paquera on the Nicoya peninsula, perhaps due to the composition of the soil.
The quake took place at a depth of 86.6 kilometers, about 54 miles.
Typically quakes that deep do not produce strong movement on the surface. But this one did. The Laboratorio in a summary of the quake said that this is not the first time that a deep quake was felt in the Central Valley. It cited the May 13, 2011, quake near Turrúcares that was about 73 kilometers deep, some 45 miles. There also was a similar event Oct. 9, 2010, that took place near the Tuesday epicenter.
