More tectonic activities.
This is another ocean quake, and seems to be no danger of Tsunamies.
Short story..

Source here
MANAGUA, Aug. 13 (Xinhua) -- An earthquake of 5.8 magnitude shook on Thursday the Costa Rica's Pacific Oceans without immediate reports of victims.

The Nicaraguan Institute of Territorial Studies (Ineter) said the earthquake occurred at 3:37 a.m. local time (0937 GMT) and its epicenter was located some 505 km south to Managua.

The Ineter added that the earthquake had some 15 km depth.

The earthquake was "an event related to the tectonic processes from the clash between the Cocos and Caribbean tectonic plates," the Ineter said.

Here is a page with some additional information on the Cocos plate in Costa Rica.

Cocos plates
Tectonic Setting

Central America’s tectonics are mainly controlled by the clash of the Cocos and Caribbean plates (see Figure 1). As a result of this clash, the Cocos oceanic plate is subducting under the Caribbean plate along the Middle America Trench at speeds that range from 70 mm/yr in front of Guatemala to little more than 90 mm/yr in front of the Osa peninsula [Protti, 1994, estimated from De Mets et al., 1990] (see Figure 2). It is along this plate boundary where most of the large-magnitude earthquakes occur in Costa Rica.
