With all this news of Colombian volcanoes, I thought I'd offer a brief tour of the action. Remember, Colombia has a few dozen potentially active volcanoes , so this activity shouldn't be too surprising. After an almost 2o year slumber, Nevado del Ruiz has sprung back to life this year , with multiple small, ashy explosions see above and constant seismicity that might be leading to more vigorous eruptions or might not. A few thousand people have needed to evacuate the slopes of the snow-covered volcanoes, mostly due to the threat of lahars generated by these explosions and rapid melting of snow and ice at the summit.
Ash continues to fall on areas around the volcano as the activity waxes and wanes as well. Nothing has occurred beyond earthquakes that suggest rock fracturing that could be hydrothermal or magma movement under the volcano.
After over years of quiet, Nevado del Huila came back to life in with a series of small explosions that has produced ash falls, lahars and lava domes at the summit of the volcano totally a VEI 3 eruption so far. The eruption is considered to be ongoing , although right now the volcano is merely steaming from fumaroles at the summit and experienced tens to hundreds of small earthquakes each week. The latest volcano to join the parade of elevated activity is Cumbal see above , a composite volcano that last erupted in Colombia has 15 volcanoes considered active.
The volcanoes are related to the subduction zone that runs along the whole of America's western plate margin. Colombia's volcanoes are part of the northern Andes and lie at the junction of 3 tectonic plates, the Nazca, Caribbean and South American plates. First visit to our site? Try our free app!
