Novinky (mesiac stare, ale bol som na dovolenke :)): Podla INETER-u, erupcia sopky Concepcion na ostrove Ometepe nad ranom 28. jula pokryla sopecnym popolom niekolko miest. Seizmicke otrasy boli zaznamenane na stanici severne od sopky, avsak zemetrasenie vasej magnitudy sa nevyskytlo. V poobednajsich hodinach spad popolceka takmer/uplne prestal, no plynne emisie pokracovali aj nadalej. Pocas erupcii nebol nikto zraneny.



Volcán Concepción is one of Nicaragua's highest (1700? m) 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.
