August:
Day 14, it happened a seismic cluster to the southwest of the town of San Jacinto. The earthquakes initiated to 09:00 p.m. 15 earthquakes in a period of 8 hours were registered. Of these 5 were located. The magnitudes oscillated between 1,9 and 3,1 Richter. The depths between 2 and 5 km. These events were not reported senses by settlers near the epicenters.

Day 30, the Chonco happened a seismic cluster to the north of the volcano. The earthquakes initiated to 12:50 a.m. 26 earthquakes in a period of 12 hours were registered. Of these 5 were located. The magnitudes oscillated between 2,0 and 4,0 Richter. The depths were minors who 5 km. The main earthquake had a magnitude of 4,0 and was felt by settlers who live near the zone of epicenters.

November:
Days 5 and 11 it happened a series of earthquakes in the sector of the volcano Wood located in the Island of Ometepe. Lamentably the amount could not be known earthquakes that happened, since the located seismic station in the skirts of the volcano were not operating by technical problems. Nevertheless they were managed to locate 3 earthquakes.

Between 24 and 26 of November it happened a seismic cluster near Apoyeque volcano. They were entered approximately more than 120 earthquakes, of which 5 were located, since most of them they were of small amplitude and only the station located in the skirts of the volcano registered the events.

The magnitudes of the located earthquakes oscillated between 2,1 to 2,9 in scale Richter, with depths of 3 to 9 km. Senses by the population were not reported that lives in the neighborhood of Apoyeque volcano.

Day 27 a series of earthquakes of volcano-tectonic type to the north of Telica volcano was registered. They were registered more than 20 events, of which 4 were located.

Surface Currents in the Caribbean Sea

The Caribbean Current

The Caribbean current as represented by the Mariano Global Surface Velocity Analysis (MGSVA). The Caribbean Current transports significant amounts of water northwestward through the Caribbean Sea and into the Gulf of Mexico, via the Yucatan Current. The source water for the Caribbean Current is from the equatorial Atlantic Ocean via the North Equatorial, North Brazil, and Guiana Currents. The counter-clockwise circulation of the Columbia-Panama Gyre is evident off-shore of southern Central America (Nicaragua, Costa Rica, and Panama) and northern Colombia.
