Video of the Week: Mexico’s Popocatépetl Volcano Explodes

Popocatépetl, Mexico’s most active and unruly volcano, is undergoing a bout of acid reflux. Mexico’s National Center for Disaster Prevention (CENAPRED) recorded the fiery explosion that initiated the volcano’s current gassy episode on their live webcam

The eruption launched plumes of ash and smoke 20,000 feet into the air and could be seen from space. No one was injured, although authorities are still warning people to stay away from the grumbling behemoth because of possible falling fragments and ash. The volcano is located approximately 40 miles southeast of Mexico City.

Popocatépetl, otherwise known as “El Popo” by locals, is over 17,000 feet high and is particularly grumpy. It erupted as recently as last summer—when it burst twice. It has a collection of small glaciers that have managed to survive its cranky behavior so far, although some have been hit by the recent volcanic activity. 

In the video, all is calm until Popocatépetl spontaneously belches out a fire ball that showers its sides with glowing red shards,followed by a thick, constant flowing stream of black smoke and ash that the volcano spews into the sky for many minutes.

Popocatépetl is a stratovolcano––tall and conical, with very steep sloping sides, and periodically erupts with fiery explosions and thick pyroclastic flows. These slow moving flows cool and harden quickly on a stratovolcano’s sides, which help maintain its cone-shaped profile. 

The National Oceanic and Atmospheric Association (NOAA) put up a satellite video clip on their twitter that also captured the eruption from space.

CENAPRED has the current warning level set to “Yellow Phase 2” which means there is no imminent danger, but that people should be wary and keep a distance of approximately 7.5 miles from the volcano. CENAPRED has also counted 248 “exhalations” of water vapor, gas—including sulfur dioxide—and ash since the explosion, and lists some pyroclastic activity, ash fall, and explosive activity of “low to intermediate level” as possible near term scenarios.
