Volcano Eruption Alert: Popocatépetl Explodes

Posted by feww on April 5, 2016

Pyroclastic surge from Popocatépetl volcano sets forest alight

Violent eruption at Mexico’s Popocatépetl produced  a Pyroclastic surge climbing 2km above the crater  and setting the nearby forest alight, said Mexico’s National Center for Disaster Prevention (CENPRED ).

The explosion also caused ashfall in the towns of Juan C. Bonilla and Coronango, in the state of Puebla.

Popocatépetl Volcano (“smoking mountain” in Aztec) is North America’s 2nd-highest volcano. The massive stratovolcano stands 5,450m high and lies about 65 kilometers (40 miles)  southeast of  Mexico City (19.023°N, 98.622°W ) in the eastern segment of the Trans-Mexican volcanic belt.

The following is latest report posted at CENPRED official website:

As of posting,  the volcano exhibited “continuous emission of steam and gas” in easterly direction (image 9), said the report.

April 05 at 11:15 (16:15 GMT)

During the last 24 hours, 96 long period events were registered and five explosions yesterday at 16:44 h (image no. 1) and 20:31 h the latter generated a ash column of 2 km height above the crater, which moved towards the northeast. Likewise, the fall of incandescent fragments were observed, mainly on the east and southeast slopes of the volcano at a distance of 3.5 km, because of this some fires were generated in the upper part of the forest (image 2), (image 3), (image 4), (video 1), (video 2), (video 3). This explosion caused ash fall in the towns of Juan C. Bonilla and Coronango, both in the state of Puebla. The remaining three explosions were recorded today at 06:54, 7:14 and 07:49 h (image 5), (image 6), (image 7), (image 8).

Additional materials: (video 4), (video 5), (figure 10), (figure 11), (figure 12).

CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 13).

This type of activity is included within the scenarios Volcanic Traffic Light Yellow Phase 2.

The scenarios forecast for this phase are:

1. Explosive activity of low to intermediate level.

2. Ash fall in nearby towns.

3. Possibility of short range pyroclastic flows and mudflows .

Special emphasis is placed on the following recommendations: Continue the safety radius of 12 km, so staying in that area is not allowed.

Earlier bulletin  177 SEGOB – Posted July 06 11:00 h (July 05, 16:00 GMT)

In the last 24 hours monitoring system Popocatepetl volcano has registered 20 hours and low to high frequency tremor, accompanied by a persistent emission of a column of gas and ash that reached 3 kilometer height, northwest direction. Additionally the monitoring system has registered 4 hours of high intensity harmonic tremor. There were also 3 explosive events of moderate magnitude, the most important of which was presented this morning at 00:33 h. Due to weather conditions due to the weather it was not possible to observe the volcano during these events. However, in the early hours of the morning the continuous emission of gases and ash that reached more than 2 miles high and heading northwest was observed. (see image 1).

The Volcanic Alert Level is at Yellow, Phase 2.

CENAPRED places particular emphasis in the following recommendations:

1. Access is restricted within a radius of 12 km from the crater. Permanence in this area is not allowed.

2. The road between Santiago Xalitzintla (Puebla) and San Pedro Nexapa (Mexico State), including Paso de Cortes, is open only to controlled traffic.
