11:00 (TL) yesterday at 11:00 (LT) Today, 25 events long period (LP) were recorded.
Observations of emissions and ash:
In the morning, the volcano was partly cloudy but no surface activity was observed.
Currently, the volcano sector is troubled by nebulosity.
Rain and lahars:
Light rain have been recorded in the area of the volcano that have not generated lahars.

GENERAL INFORMATIONS

If rainfall appear with more intensity in the volcano area, they can re-mobilize the deposits of pyroclastic flows and generate lahars .
For this reason, we recommend extreme caution when driving on roads which cross rivers by which these flows are down and in areas which, in the past, have been affected by this phenomenon.


This daily report will be published at 12:00 (TL). If an increase or a change in the behavior of the volcano occurs it will immediately issued a special report.

Popocatepetl, Mexico :

December 14, 11:00 h (December 14, 17:00 GMT)

In the last 24 hours the seismic records of the surveillance system at Popocatépetl volcano registered on the one hand 34 low-intensity exhalations with slight amounts of ash. Also were recorded 7 explosions .The cloudy conditions not allow observing a weak emission of steam and gas that winds carried northeasterly . In addition, was recorded low amplitude harmonic tremor totaling 16 minutes.


Along some lapses of the night was observed slight incandescence, increasing when main exhalations .
From dawn and up to the time of this report it has been noticed a faint but not stopping emission of steam and gas that winds blow about northeast .
CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments .

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