Popocatepetl volcano news & eruption update
Popocatépetl volcano (Mexico): strong explosion yesterday morning sends ash to 32,000 ft (10 km) altitude
At least 3 other, but smaller explosions also occurred during a 24 hours interval (at 18:22 on 13 June, 04:33 and 08:54 on 14 June, local time). Overall, the daily average of explosions and exhalations (low-pressure emissions of steam and sometimes ash) has clearly increased compared to some weeks ago. However, no lava dome has yet formed in the inner summit crater.
During an overflight on 11 June, it was observed to have a similar configuration as observed in late April, about 350 m wide and intensely degassing.
A volcanotectonic earthquake was recorded on 13 June at 20:40 local time with a magnitude of 1.9 and 27 minutes of tremor.
The alert level of the volcano remains unchanged at Yellow Phase 2.
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.
