Popocatepetl volcano news & eruption updatePopocatépetl volcano (Mexico): increased activityMo, 29. Apr 2013, 09:55 09:55 AM | VON: T  Explosion from Popocatépetl yesterday morning  Current seismic signal from Popocatépetl
Activity at the volcano has picked up in the past 48 hours. Following an earthquake swarm on Saturday with volcanic-tectonic quakes of magnitudes up to 2.3, which was probably the result of a new magma batch rising, an increase in small emissions occurred yesterday with 71 events registered during 24 hours. The largest emission yesterday (at 10:33 local time) produced a steam and ash plume rising 1.2 km above the crater and drifted NE. A similar earthquake swarm is visible on today's seismograph (but CENAPRED's report about this will only be available later today). Vorherige NachrichtenActivity is on the increase again at the volcano, which currently is producing a strong steam plume illuminated by the glowing lava in the summit crater. ... alles lesenA moderate-sized explosion occurred yesterday, producing an ash plume rising 1.2 km and throwing incandescent bombs to 500 m distance on the outer flanks of the volcano. Small explosions occur at an average rate of one per hour and a large steam plume is often rising to about 1 km above the crater. Incandescence continues to be visible at night at the crater. alles lesenActivity continues with no significant changes: weak emissions of steam/gas/ash occur at rates of approx. once per hour, and glow at night shows that magma continues to arrive slowly in the summit crater. ... alles lesenActivity has decreased to about one emission of gas/steam/minor amounts of ash per hour over the past few days. Glow remains visible at night from the crater. ... alles lesenA stronger-then-usual explosion occurred last night (23:23 h local time) and produced a plume of ash rising about 2 km above the crater. Incandescent fragments were thrown to distances of 900 m. ... alles lesenBackground:Volcán Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America's 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 250-450 m deep crater. The generally symmetrical volcano is modified by the sharp-peaked Ventorrillo on the NW, a remnant of an earlier volcano.
At least three previous major cones were destroyed by gravitational failure during the Pleistocene, producing massive debris-avalanche deposits covering broad areas south of the volcano. The modern volcano was constructed to the south of the late-Pleistocene to Holocene El Fraile cone. Three major plinian eruptions, the most recent of which took place about 800 AD, have occurred from Popocatépetl since the mid Holocene, accompanied by pyroclastic flows and voluminous lahars that swept basins below the volcano. Frequent historical eruptions, first recorded in Aztec codices, have occurred since precolumbian time.
