Popocatepetl volcano news & eruption update
An eruption plume from Popocatépetl rose to an altitude of 7.9 km (26,000 ft) a.s.l. and drifted E on 20 December, 2006....БОЛЬШЕ
Popocatepetl had a strong explosion on 25 July at 09h50 local time, producing an ash and gas plume of 5 km height above the crater. The eruption lasted 1 and a half minute and was accompanied by high-frequency tremor. It is believed that the explosion was caused by interaction of water from the recent heavy rains with the hot lava dome inside the crater....БОЛЬШЕ
During the past weeks, occasional and small steam-and-gas emissions continued at Popocatépetl. Airphotos taken on 10 February showed a 130-m-diameter lava dome at the bottom of the crater.
Popo remains much unchanged; small steam and gas emissions, some producing minor ash plumes, averaging in number 5-10 per day are being observed by CENAPRED. A new lava dome is probably continuing to grow slowly inside its crater; it had last been observed in mid November last year.
Popocatepetl continues to emit small-to-moderate emissions of steam, gas, and small amounts of ash. On 4 February 2006, an explosion produced a plume that rose to ~6.7 km (22,000 ft) a.s.l.
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.
