From Frederick A. Belton’s Mountain OF God site:

September 2007: Leander Ward reports on the status of the eruption as seen by his staff at a camp north of Lengai on the lower slopes of Gelai-” The day befor yesterday (Sept 11) was the most significant eruption there has been, aside from perhaps the first day, with much rumbling and more fire visible at night as well as huge ash plumes, although this is secondhand information as I was away from the location. But it scared my staff to the point that they evacuated against our wishes. As of Sept 13 there is still significant black smoke but it has subsided considerably.”

The Government of the State, through the State Unit of Civil defense Sights on, informs that they follow without new features about seismic activity in the cone of the Fire Volcano of Sights on in last the twenty-four hours, period in which, most of the time, he has remained dimmed preventing the visibility of exhalations or fumarolas; also, he indicates that report of damages or affectation in the adjacent populations is not had.

In the occasion of the rain storm, which is reported that to the storm clouds light rains and sporadic electrical storms in the top of the volcano are added, forces to remember to the population that avoids the permanence in bordering ravines, before the possibility that they register lahares (mud flows).

On the other hand, it continues the restriction for the sobreflights that do not have scientific aims or of civil defense, and is prohibited the permanence of people other people’s to these activities in ravines of the volcano.

In permanent coordination with the State Unit of Civil defense Jalisco, the Government of the State of Sights on is pending of monitorear the activity of the volcano in real time; this way, he counts himself on opportune information to be able to respond before any contingency and to guarantee the security of the population, as it is the interest of the governor Jesus Silverio Cavazos Ceballos.

In addition, one works in the preventive programs to maintain informed to the citizens on the evolution into the volcanic activity, and to avoid that alarm by rumors is generated.

Also constant communication with the communitarian brigade that has formed with inhabitants of the town of the Becerrera, to those who exists has become qualified in the self-protection with respect to the natural disasters. Also, permanent contact with the personnel of the military team of Marijuana, the Becerrera stays, farm the Wild boar, as well as with elements of public security of the State, Comala and Civil defense of Cuauhtémoc.

The radius of preventive alert remains in 11.5 kilometers from the top of the volcano, which includes the populations of Marijuana, and the Becerrera in the state of Sights on, and Causentla, Brotherhood of Tonila, Atenguillo, the Saucillo, the Fresnal, the Funnel, Juan Barragán, the Males, the Summer pasture and the Borbollón in Jalisco.

Soufrière Hills Daily Update for 9/13/07

Current Soufrière Hills status from MVO:

13 September 2007

The alert level remains at 4.

Measurable activity of the Soufrière Hills Volcano has remained low with no significant change over the last 24 hours.

Popocatepetl Daily Update for 9/13/07

Current Popocatepetl status from CENAPRED:

September 13 11:30 h (16:30 GMT)

In the last 24 hours the monitoring system of Popocatepetl volcano registered only 2 exhalations accompanied by steam and gas emissions. The other monitoring parameters remain without important changes.

At this moment we can observe the volcano with a steam and gas emission (see imagen).

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).

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.
