The volcano's lava dome has filled the inner crater, CENAPRED observed during an overflight on 27 January. The high level of the dome explains the relatively strong glow visible at night. Read all

Explosion from Popocatépetl last night (CENAPRED)
No significant changes have occurred during the past weeks at the volcano. Magma is slowly rising and growing a flat dome in the inner summit crater. Trapped, pressurized gasses cause small to moderate explosions with more or less intense ash emissions from time to time, typically a few per day: Read all

CENAPRED reported that during 20-23 and 25 January the seismic network at Popocatépetl recorded 16-68 daily emissions consisting of water vapor, gas, and ash, and 2-5 explosions per day. At 1000 on 23 January an increase in activity was characterized by continuous gas-and-ash emissions, likely related to the destruction of a recently-formed lava dome. Later that night cameras recorded incandescent fragments ejected during periods of emissions. Read all
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.
