Ash fall map of the 8 Sep eruption (INETER)
No significant seismic activity is recorded. INETER keeps a close watch of the volcano with 2 groups of geologists and volcanologists together with Civil Defence. Analysis of the eruption on 8 Sep gives the following data:
1. The ash fall covered an area of about 2.438 square kilometers (see attached map), distributed in the northwest that includes the municipalities of Puerto Morazán, Potosi, El Viejo, and the towns of Punta Jiquilillo and Punta Ñata. The height reached by the ash was approximately 5,000 meters above the craters and the maximum ash fall deposit was 5 inches in areas very close to the crater, while it was only up to 3 millimeters in more distant places.
2. According to information from Mr. Francisco Ramos Galeano, a resident of the area, there were landslides in the northern part of the crater with falling rocks.
3. Similarly, it was reported that in the northwestern part of the volcano ash and incandescent rocks fell, which caused severe burns to 6 livestock.
4. Inhabitants of the area of Versailles Top, very close to the crater of the volcano, reported having seen a crack or fissure in the earth. INETER specialists will be going to investigate this in the field.
5. For the afternoon and evening there are high chances of rain with thunderstorms in the Department of Chinandega. These rains can increase the emission of gas in the San Cristobal volcano, making acid rain. Surface winds are expected in about 10 km / h. Rains when these winds can reach speeds of up to 20km / h.

Currently, no ash is visible on satellite data. In the latest message 11:33 GMT today, VAAC Washington reports that ash emissions are likely, but not identifiable on imagery due to weather clouds. INETER has not issued further bulletins. This suggests that the eruption has decreased a lot compared to yesterday already.Update Sun 09 Sep 18:18
