Popocatepetl volcano news & eruption updatePopocatépetl volcano (Central Mexico) activity updateSa, 16. Mär 2013, 16:46 16:46 PM | VON: T  Current seismic signal from Popocatépetl
The rate of emissions has dropped back to less than one per hour. Tremor has dropped as well, but two probably shallow volcanic quakes show up on the recent seismogram. Vorherige NachrichtenA phase of increased, near-constant steam-gas-minor ash emissions has taken place this morning, accompanied by a small swarm of quakes and volcanic tremor. alles lesenActivity has remained stable, with 1-2 weak weak to moderate steam-gas-ash explosions per hour, some of which generated small ash plumes. Incandescent bombs can sometimes be seen ejected at night. ... alles lesenThe frequency of emissions has increased to almost 3 per hour, with some explosions producing low ash plumes. Degassing remains strong and an important SO2 plume is drifting eastwards from the volcano. ... alles lesenActivity (internal and external) has decreased again to levels similar to past weeks. Glow is visible at the summit, and degassing (SO2) remains elevated. ... alles lesenAsh emissions continue. A plume rises to at about 27,000 ft (7 km) altitude (or approx. 1500 m above the crater) and drifts east. 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.
