Popocatepetl volcano news & eruption update

Popocatépetl volcano (Central Mexico) activity update: growing lava dome, occasional explosions ejecting fragments up to 500 m distance, ash plumes 1-2.5 km height

Dienstag Mai 08, 2012 10:05 | VON: T

CENAPRED reported that during 2-3 May activity at Popocatépetl increased significantly.
Spasmodic tremor was detected along with a dense and continuous plume of gas and ash that drifted W, NW, and NNE. Ash fell in multiple areas, including Amecameca (20 km NW), Atlautla, Ozumba (18 km W), Ecatzingo (15 km SW), Chalco (35 km NW), and some parts of SE México City (70 km NW). On 3 May gas-and-ash plumes rose 1.5 km above the crater and drifted W and NE. Incandescent fragments ejected from the crater landed on the flanks as far as 800 m away.
Explosion-generated gas-and-ash plumes the next day rose 2.5 km above the crater and drifted NW. Spasmodic tremor was detected along with a dense and continuous plume of gas and ash that drifted WNW. Later that day gas-and-ash plumes rose 1 km. During 5-6 May gas-and-ash plumes rose 1.5 km above the crater and drifted N, NE, and E. Light ashfall was reported in Atlixco (25 km SE), San Juan Tianguismanalco (22 km SE), Tochimilco (16 km SSE), San Pedro Benito Juárez (10 km SE), and San Nicolás de los Ranchos (16 km ENE). During 5-7 May incandescent fragments ejected from the crater landed on the flanks as far as 500 m away. A gas-and-ash plume drifted ESE on 7 May. The next day activity remained high; seismic events were accompanied by dense and continuous plumes of steam, gas, and ash that drifted mainly ESE. The Alert Level remained at Yellow Phase Three.

CENAPRED has raised the alert status of Popocatépetl to the third highest level (5 out of 7) and considers the possibility of a major eruption. The volcano continues to have elevated levels of seismicity, and produces frequent steam and ash emissions raising about 1 km above the crater. ... [mehr]

Background:

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.
