Popocatepetl Daily Update for 7/27/07
Current Popocatepetl status from CENAPRED:
July 27 11:00 h (16:00 GMT)
In the last 24 hours the monitoring system of Popocatepetl volcano registered 8 exhalations accompanied by steam and gas emissions. The other monitoring parameters remain without important changes.
At the moment of this report there is no visibility to the volcano due to the clouds. However, this morning we could observe it with steam and gas emissions (see image 1), (see image 2).
A vertical photo of the crater, obtained by the Dirección General de Carreteras Federales (SCT) on March 6, shows that the dimensions of the lava dome inside the crater do not have a significative change in comparison with those observed on January 24, 2007. This condition does not imply significant change in the expected scenarios(see image).
The kind of activity in the last days has been related, in the past, with movements of material inside the volcano, so there is a probability that the lava dome inside the crater of the volcano is still growing.
From high to low probability the expected activity scenarios in the next hours, days or weeks are: moderate exhalations, some with ash emissions; occasionally mild incandescence during nights and sporadic low level explosions with low probabilities of incandescent fragment at short distance to the crater.
There is a permanent monitoring of the volcano to detect any change. The traffic light of volcanic alert remains in YELLOW Phase 2.
Recommendations:
1. Access is restricted in a radius of 12 km from the crater. For this reason the 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.
3. To the authorities of Civil Protection, maintain preventive procedures, according to operative plans.
4. To the population, to be aware of the official information emited.
