Taal volcano exhibiting signs of increased unrest

April 1, 2011 PHILIPPINES – Signs that some sort of eruption might be in the works continue at Taal. PHIVOLCS released a warning today about increasing carbon dioxide emissions at Taal, which that apparently quadrupled since this time last year – from ~1,000 tonnes/day to 4,600 tonnes/day. The current values are double that was observed in January of 2011. All of this suggests that magma is actively degassing somewhere under the volcano, and the increasing levels of CO2 suggest the magma might be slowly rising towards the surface. This does not mean an eruption is imminent or that any eruption would be catastrophic. On the contrary, the likelihood is high for a small eruption, starting as phreatic in nature and the hazard maps for Taal reflect this. Tourists and locals were warned to be wary of the threat of these increased carbon dioxide emissions and avoid the crater of the volcano. PHIVOLCS issued a full report on the current activity at Taal that includes this increased carbon dioxide emissions, increased seismicity, periodic increases in steam emissions and very slight inflation – a combination that all indicate a higher probably of eruptive activity. It would seem that Taal is a volcano we should all watch very carefully in the near future. –Big Think
