Mayon alert status lowered from 4 to 3 3 SHARES Share it! Share TweetBy Ellalyn de Vera-RuizThe Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday morning lowered Mayon Volcano’s alert status from 4 to 3 due to the restive volcano’s “decreased tendency towards hazardous eruption.”Phivolcs said Mayon Volcano’s condition last week has been characterized by a general decline in unrest reflected by moderate seismicity and degassing, deflation of the edifice and a decrease in eruptive activity. From Monday to Tuesday, only four volcanic earthquakes and 44 rockfall events were recorded by the Mayon Volcano’s seismic monitoring network. However, Phivolcs clarified that Mayon Volcano is still inflated relative to January 2010 baselines. Mayon Volcano’s sulfur dioxide flux throughout the eruption has varied from a maximum of 4,270 tons/day on February 21 to 1,400 tons/day on March 3.
