Concepción , Nicaragua : A collapse in the Concepción Volcano, has affected 276 square kilometers.

A collapse in the Concepción Volcano, located in the Nicaraguan island of Ometepe, has affected 276 square kilometers. According to the Risk Unit of the Mayor of Altagracia, rainfall has generated lahars in the communities of La Chirca (north of the volcano), and the La Union and Los Ramos (both southeast of the Colossus), without affecting housing and people in these communities.

A layer of sand and mud was deposited on the street in La Union and Los Ramos, and mixed with mud and sand in La Chirca, which are already being cleared, as the coordinator of the Council of Communication and Citizenship stones, Rosario Murillo. Continuing heavy rainfall in the area is more likely the occurrence of similar or stronger events, so people are encouraged to be vigilant and attentive to the guidelines of the Government, the Nicaraguan Institute of Territorial Estuidos (INETER) said.

The associated lahar (mudflow with stones) signal was observed in the seismogram stations Concepción volcano, between 12:10 and 1:05 am on Wednesday (local time).

On the other hand, from 12:00 pm on Tuesday, October 13 and 12:00 on Wednesday, 14 eight quakes were registered in the country, seven of which occurred in the local faulting and one in area subduction.

Volcán Concepción is one of Nicaragua’s highest and most active volcanoes. The symmetrical basaltic-to-dacitic stratovolcano forms the NW half of the dumbbell-shaped island of Ometepe in Lake Nicaragua and is connected to neighboring Madera volcano by a narrow isthmus. A steep-walled summit crater is 250 m deep and has a higher western rim. N-S-trending fractures on the flanks of the volcano have produced chains of spatter cones, cinder cones, lava domes, and maars located on the NW, NE, SE, and southern sides extending in some cases down to Lake Nicaragua. Concepción was constructed above a basement of lake sediments, and the modern cone grew above a largely buried caldera, a small remnant of which forms a break in slope about halfway up the north flank. Frequent explosive eruptions during the past half century have increased the height of the summit significantly above that shown on current topographic maps and have kept the upper part of the volcano unvegetated.
