The 85 recorded earthquakes between Saturday and Sunday in the Caribbean Sea, which have been felt by the residents of San Andrés and Providencia, have generated an alert in the community. However, according to the Colombian Geological Survey (GSC), this responds to a release of energy in the Caribbean tectonic plate, as we know, who is in a sort of "rearrangement process".
Martha Lucía Calvache, director of Geoamenazas of the SGC, told EL COLOMBIANO that this process is "normal"although that does not mean nothing will happen. "What we have to do is check in the houses elements that are in raised or heavy areas, such as libraries, to avoid emergencies, because when there are earthquakes, the dead usually occur when structures fall, "he explained.
Similarly, Calvache emphasized that it was necessary to be attentive to information from the corresponding authorities and do not believe in false information which is circulating through social networks or a messaging application, such as WhatsAppwhat are the means by which citizens are changed, because they share false information.
On the island
For the attention of the authorities, the district chief Everth Hawkings He pointed out that the seismic information recorded on the island was clear and instantaneous, which rebadured them in a certain way, since they note that at least the government is working with the community.
L & # 39; Rear Admiral Juan Francisco Herrera, who is the acting governor, badured that the work of strengthening the risk management plans for the identify the strengths of the archipelago in case of flood recording and the community knows where to go.
In addition, the Director of Geoamenazas of the SGC stressed that there is no threat of tsunami on the island and recalled that since November 14, "the Geological Service had set up a field commission with the collaboration of the Ministry of Defense, Dimar, Navy, Air Force and the National University for the installation of three seismological satellite monitoring stations in Cayo Serrana, Cayo Roncador and the island of San Andrés "(see infographic).
On the fears of the community, for the possibility of recording tsunamis as in Japan, for example, Calvache said that given the characteristics of the movement of this plate, there is not enough of 39 energy to generate waves of dimensions seen in this country; However, explained the expert, landslides could occur at sea, which could "cause waves a few centimeters, of a height not exceeding one meter".
In this regard, the responsible governor made it clear that even if there was no warning message, they reinforced the focus and risk management plans.
This is not new
The Geological Survey has indicated that other earthquakes have been recorded in the insular area, similar to those of last weekend, such as those of March 17, 1926, with a magnitude of 6.9 and the most recent, March 16, 1926. June 2014, magnitude 5.3. Although the report says that there were 85 earthquakes over the weekend, he says that there was more movement between Monday and Tuesday.
"Although seismicity is not common in the Colombian Caribbean, the region is no stranger to movements when energy accumulates, as is happening nowadays," says the director of Geoamenazas, SGC.
Adjust plans and construction
The governor in charge, Rear Admiral Juan Francisco Herrera, also indicated that he wanted to adapt the emergency plans and risk management systems in San Andrés and Providencia. The National Risk Management Unit will conduct community visits to check the condition of housing. and the infrastructure of the island in general. Given this, the geological service also recommended to identify the points "with the threat of landslides to intervene".
