No ash emissions have been detected during the past 48 hours, the crater shows only a degassing plume, but alert level remains at red, because new explosions could occur any time. The government has extended the emergency status until at least 21 December, which implies that the more than 17,000 evacuees remain in the total of 31 shelters. Their situation is difficult, with help needed in form of food, water, medicines and sanitary supplies.
Blog Culture Volcan has posted an interesting comparison of clear webcam images over the past weeks, that illustrate the progressive opening of 3 distinct vents. This also helps explaining the observed shift from discrete vulcanian explosions towards semi-continuous ash venting: as more vents became available, it is easier for the volcano to release gas and thus, decrease pressure build-up.
