After almost a one month of bit calmer period-than-usual with no explosions and characterized by the near-constant degassing activity with only venting water vapor and gases, it occurred two minor eruptions at the volcano.
Explosions started around 20:01 and 20:43 local time on 16 Jul evening. Ash emissions reached 19,000 ft (5,800 m) altitude and drifted W.
74 emissions of water vapor, gases and small amounts of ash were recorded.
The seismic instrument recorded 457 minutes of volcanic tremor.
Incandescence continues to be observed in the summit crater at night and caused small avalanches of glowing lava blocks that rolled down along the slopes as visible in the attached image.

Popocatépetl Volcano Volcanic Ash Advisory: VA NOT OBSD

Popocatépetl Volcano Volcanic Ash Advisory: REMNANT VA CLD to 20000 ft (6100 m)

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.

Stromboli Trekking

Climbing Stromboli volcano
Stromboli provides one of the most remarkable opportunities to watch volcanic eruptions from close: a natural ridge located 150 m above the active vents. A classic and all-time favorite tour by anyone interested in seeing active volcanoes!
