The Pacific coast experienced another shaker at 6:48 am on Wednesday.
According to the Observatorio Vulcanológico y Sismológico de Costa Rica in Heredia, the epicenter of the earthquake was about 15 kilometers (about nine miles) south of Sámara on the Nicoya peninsula in the Pacific Ocean. The estimated location is about 130 kilometers or 80 miles west of San José.
The cause of the quake was an interaction between the Coco and Caribe tectonic plates. There were no reports of serious damage or injury.
A 4.0 magnitude earthquake took place Thursday at 2:38 p.m. in the Pacific, just west of a small village of Parrita.
As usual, the cause was attributed to the collision between the Caribe and the Coco tectonic plates.
The quake was felt in Jacó and other towns along the Pacific coast.
The Observatorio Vulcanológico y Sismológico de Costa Rica reported 12 quakes Monday. They ranged in magnitude from 1.5 to 3.2. A local fault is being blamed for a flurry of earthquakes that have been detected in the vicinity of the Irazú Volcano.
The observatory said that the quakes were located a few kilometres northeast of the volcano crater and that they had no relationship with volcanic activity. The quakes took place in less than an hour from 7 pm to 8 pm.
Irazú volcano has been emitting acidic gas and steam for several months now and access to the Turrialba volcano has been closed completely.
Southern Costa Rica got another jolt this Tuesday. An earthquake estimated at a 5.0 magnitude took place at 12:22 p.m. That was less than a day after a quake estimated at 4.4 magnitude took place near Quepos (Central Pacific). Read more »
An earthquake of a magnitude of 4.4. took place near Quepos at 8:50 p.m. Monday.
The Obvservatorio Vulcanológico y Sismológico de Costa Rica said the epicenter was about 15 km (9 miles) northwest of Quepos. Read more »
The first at 8:59 a.m. was in the southern zone about 8 kms (about 5 miles) northeast of Sabalito, said the Red Sismológica Nacional at the Universidad de Costa Rica. The magnitude was estimated at 4.
The second was at 1:10 p.m. in Carrizal de Alajuela. It registered a magnitude of 4.6, said the Red Nacional. Gentle rocking could be felt throughout the Central Valley.
Five earthquakes in the 4.7 to 5.2 magnitude range shook up the southern zone on Friday and Saturday. Then a smaller quake stroke Pacayas at 9:24 a.m. on Sunday.
Quakes in the southern zone are not unusual. Three tectonic plates come together in that area. There is the Coco, the Caribe and the Panamá Block. The most frequent culprits are the Coco and the Caribe. Read more »
A 5.1 magnitude earthquake shook Costa Rica Friday at 3:20 p.m.
The Costa Rican Volcanology and Seismology Observatory (OVISCORI) said the earthquake's epicentre was located 20 km northeast of a tiny town of Parrita central Pacific).
The earthquakes' epicenter was 19 km underground and it occurred due to a local geological failure.
There were no immediate report of victims or any damages.
The earthquake was somewhat strongly felt in the Central Valley (San Jose, Grecia, Atenas, San Ramon).
The early morning quake was felt at 3:40 am Sunday in Bagaces.
An earthquake registering 3.2 on the Richter Scale rocked the areas of Fortuna de Bagaces Sunday morning, bringing the total number of quakes just during the past week to 7, all between 2.4 and 4.2. Several of the quakes were in the vicinity of the Poas volcano (in Alajuela province), close to Cinchona, where a devastating January earthquake still has the area recovering.
Experts are saying that for this time of year this type of activity is normal.
Today the Observatorio Vulcanológico y Sismológico de Costa Rica re-evaluated the quake from 4.5 to 5.4 magnitude. The quake hit southern Costa Rica late Saturday night (around 11 pm).
The Observatorio said the tremor was felt in Rio Claro, Quepos, Cartago,Ciudad Neily, Buenos Aires, San Jose, and, of course, Golfito. The epicenter is now reported to be at about 20 kilometres (10 miles) east of Golfito.
The cause of the Golfito quake was reported to be movement of the Coco and Caribe tectonic plates.
There still have been no reports of serious damage in Costa Rica or Panama.
The 4.5 quake jolted the Pacific zone of Costa Rica Saturday night around 11 p.m.
According to the US Geological Survey (monitors earthquakes around the world), the epicentre was 10 kilometres from Golfito. Read more »
A quake of 5.6 magnitude was recorded today in the morning around 3:30 am. Scientists attributed the earthquakes in this area to friction between the two tectonic plates, the Caribe and the Coco, but they admitted that it’s unusual to have a quake in this part of the Pacific Ocean. Read more »
The money for the Observatorio Vulcanologico y Sismologico de Costa Rica came from the national emergency commission.The director of the observatory, said that all of the 1.4 billion colones will go on improvements to the monitoring systems. The money will be used to provide real-time monitoring of the 4 most active volcanoes of Costa Rica: Arenal, Poas, Irazu, and Turrialba.
