Popocatépetl volcano (Mexico): pictures of crater, lava dome #52 destroyed

Activity at the volcano has remained low, with small occasional steam, gas and sometimes ash emissions. Incandescence was observed over the crater during the night.
During an overflight on 14 Oct "it was observed that the inner crater, formed in July 2013, has increased its diameter, probably due to the destruction of the dome and walls collapsing, reaching an estimated 350 m diameter. The bottom of the inner crater is about 100 m below the floor of the main crater.
No residues were observed of the 52nd dome, which was emplaced in the bottom of the inner crater early last August. Instead, the bottom of the inner crater is cup-shaped and is covered with tephra (fragmented material) Most emissions of steam are coming from a crack in the north wall of the inner crater, while ash emissions, originate in the bottom of the crater, in the area covered by tephra.
The video shows in detail the internal cráter, that is 350 m in diameter and 100 deep (VIDEO). The emission of an intermittent small plume of brown ash can be seen originating from the tephra-covered bottom of the crater, which lasted under one minute. This plume corresponds to the signal detected by teams CENAPRED at 11:38. Some white fumaroles are also observed in the crater wall.
These observations confirmed that the explosions occurred in late September and early October destroyed the 52nd dome, and that the activity that the volcano has recently presented continues the cycle of construction and destruction of domes that has characterized the Popocatépetl in the last 20 years."

Wednesday, Oct 01, 2014
No significant changes have occurred during the past weeks. The volcano's activity has been characterized by constant degassing and occasional small explosions with ash plumes up to 1-2 km height. Crater glow is visible at night from the summit. [meer...]
Stoom pluim van Popocatépetl gisteren
Wednesday, Aug 27, 2014
Activiteit blijft in wezen onveranderd en is relatief laag. De vulkaan straalt een pluim van gas-stoom allermeest naar de tijd en af en toe heeft kleine explosies die kleine hoeveelheden voor ash uitwerpen. [meer...]
Kleine uitbarsting op Popocatépetl vulkaan vanochtend
Sunday, Aug 24, 2014
De vulkaan had een fase van sterkere activiteit vanochtend, maar over het geheel genomen blijft dit vergelijkbaar met de afgelopen maanden. Een discrete explosie uitgeworpen een ash plume ca 1 km hoog en een fase van sterke stomen, eventueel met enkele as emissies, opgetreden vanmorgen. ... [meer...]

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.
