Increasing carbon dioxide emissions at Taal cause concern

Over the last year, we've been hearing about unrest at the Taal caldera in the Philippines. Last year, PHIVOLCS even raised the alert status briefly when seismicity at the volcano increased to a level that raised concerns it could erupt. The seismicity waned and the alert status was lowered, but PHIVOLCS has been keeping a close eye on the caldera that sits a mere 50 km from the capitol of the Philippines, Manila. The volcano is a case where careful monitoring and mitigation will hopefully save lives - one of the reasons it was a Decade Volcano.
