Resumen de las últimas 24 horas:

December 07, 11:00 h (December 075, 17:00 GMT)

In the last 24 hours, the Popocatépetl volcano monitoring system recorded 577 low-intensity exhalations of steam and gas. The most important were registered yesterday at 23:45 h (image 1), and today at 05:35 (image 2) and 06:14 h (image 3); all generated eruptive columns less than 1 km in height. Also, two volcanotectonic seisms were registered, the first yesterday at 21:28 h, of magnitude 2.3, and the second this morning at 01:26 h, with a magnitude of 1.7.

From dawn and until the moment of this report a ligth, continuous emission of steam and gas has been observed (image 4).

CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 5) and in case of heavy rains leave the bottoms of ravines by the danger of landslides and debris flows.

The Volcanic Traffic Light Yellow Phase 2.

The scenarios foreseen 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:

1. Continue the safety radius of 12 km, so staying in that area is not allowed.

2. Keep the controlled traffic between Santiago Xalitzintla and San Pedro Nexapa through Paso de Cortés.

3. Civil Protection authorities, keep your preventive procedures, in accordance with their operational plans.

4. People, be alert to the official information disseminated.

In case of ashfall, address the following recommendations:

• Cover nose and mouth with a wet handkerchief or face mask.

• Clean eyes and throat with pure water.

• Avoid contact lenses to reduce eye irritation.

• Close windows or cover them up, and stay indoors as much as possible.

Popocatepetl Volcano monitoring is performed continuously 24 hours a day. Any change in activity will be reported in due course.
