Popocatépetl volcano (Mexico): new lava dome growing inside summit crater
Monday Jul 08, 2013 16:56 PM | BY: T
An overflight yesterday showed that the activity of the last few days has formed a new lava dome that has filled the inner crater and reached approximately 250 meters in diameter.
Activity remained elevated (but a bit lower than two days ago) with a near-constant emission of gas, steam and ash, interrupted by some discrete explosions in between.
Additionally, a 1.9 magnitude volcano-tectonic earthquakes was recorded yesterday. Overall, tremor has decreased during the past 24 hours.
Weather did not allow much visual observation of the volcano recently.
The Volcanic Alert Level remains at Yellow, Phase 3.
CENAPRED posted an annotated seismogram showing the high-level tremor phase yesterday - thanks to all CENAPRED staff!

After being a bit calmer during the first half of the day, compared to last night, a strong eruption occurred around 19:00 GMT (10:00 local time) and is probably continuing, judging from the seismic signal. ... [more]
The intensity of the current eruptive phase has been easing a bit during the night. Explosions and gas and ash emissions have become more intermittent, but still produce plumes reaching 3-4 km above the volcano. ... [more]

A phase of strong eruptive activity has started last night and is continuing with frequent explosions that eject incandescent bombs onto the upper outer slope and create a plume of gas and ash rising 3-4 km above the volcano to flight level 250 (25,000 ft). ... [more]
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.
