Activity has remained low with only weak emissions at averages of 1 every 1-2 hours. Occasionally, some ash explosions still occur, with plumes up to about 1 km height. Crater glow can still be seen at night and SO2 emission is strong, two indicators that magma continues to arrive at the summit (although at reduced rate).
No significant changes in activity have occurred. The number of small emissions has sunken to less than one per hour average. The largest during the past 24 hours occurred this morning producing an ash plume rising 1.5 km above the crater. ...Read all
Activity has remained at generally low levels with no large fluctuations. During 18-19 Sep, the number of small to moderate emissions has risen to about 2 per hour. Some of these events produced ash plumes up to about 1 km height, but frequent cloud cover prevented observation most of the time.Read all
A moderate explosion occurred yesterday at 07:03 (local time), producing an ash plume that rose about 2 km above the crater. The event was accompanied by small amplitude volcanic tremor, and a volcano-tectonic earthquakes of magnitude 2.6.Read all
Activity continues at generally low levels. The rate of small emissions of steam and gas has risen to more than 5 per hour during yesterday, and a number of small volcanic-tectonic quakes and episodes of tremor were recorded.Read all
Activity has been low over the past days with little changes overall. The volcano continues to produce important degassing and has occasional small explosions. Glow at the summit can be seen when the weather is clear, indicating that lava continues to slowly extrude in the crater. ...Read all
At 19:02 h (local time) yesterday, an phase of strong ash emissions occurred accompanied by strong volcanic tremor. Due to cloud cover, the eruption was not observed directly, but fine ash fell in areas west of the volcano, including the towns of Ozumba and Tepetlixpa in the State of Mexico. ...Read all
Activity has remained more or less at similar levels during the past days. During 11-12 August, CEAPRED reported 88 mostly weak emissions and a stronger explosion yesterday morning that produced an ash plume rising about 2.5 km above the crater. ...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.
We truly love working to bring you the latest volcano and earthquake data from around the world. Maintaining our website and our free apps does require, however, considerable time and resources.
We need financing to increase hard- and software capacity as well as support our editor team. We're aiming to achieve uninterrupted service wherever an earthquake or volcano eruption unfolds, and your donations can make it happen! Every donation will be highly appreciated. If you find the information useful and would like to support our team in integrating further features, write great content, and in upgrading our soft- and hardware, please make a donation (PayPal or Online credit card payment).
Improved multilanguage support
Thanks to your past donations, these features have been added recently:
