Quoted from article here: http://newsinfo.inquirer.net/741835/alert-level-1-up-in-kanlaon-volcano-after-steam-explosion Quote "Prior to Monday night’s steam explosion, only four volcanic quakes were recorded in Kanlaon. However, a volcanic tremor which lasted five hours has since recorded after the explosion." That's not a good sign. DaveD
The public here was urged to wear masks and to stay at home following the ash eruption of Mount Kanlaon in the neighboring province of Negros Oriental on Sunday, December 27. Zeaphard Caelian, chief of the Negros Occidental Provincial Disaster Management Program Division, said that the ash fall from the volcano affected some localities here, which had caused some residents to panic. According to an advisory issued by the Philippine Institute of Volcanology and Seismology (Phivolcs), the ash eruption from the active crater of Mount Kanlaon occurred at 1:29 pm and lasted for 5 minutes. The Phivolcs report said that rumbling sound was heard in Barangay Cabagnaan, La Castellana town, and barangays Ara-al and Yubo in La Carlota City, all in Negros Occidental. The same report said that the eruption plume was observed through cloud cover, adding that traces of light ashfall were reported in La Carlota City and Pontevedra town. According to Caelian, the wind blew southwest from the eruption site in Negros Oriental, thus bringing ash fall on to some local government units in Negros Occidental. He said there’s no need for the public to panic as the ash eruption was just a “phreatic activity” of the volcano. Negrenses urged to wear masks, stay home after Kanlaon ash eruption
