Sulphur dioxide emission increased to 752 tons per day at Mayon volcano in Philippines. Mayon produced two volcanic earthquakes on Sunday. Between 10 to 16 of August 57 volcanic earthquakes were recorded. The crater glow was at Intensity 2 and its steaming activity still remains at moderate levels. Ground deformation shows no change compared to June 2009, but still inflated by 8mm compared to February 2008 baseline data. PHIVOLCS has warned active river channels and those areas perennially identified as lahar-prone in the southeast sector should be avoided especially during bad weather conditions or when there is heavy and prolonged rainfall. A 6 km radius Permanent Danger Zone around the volcano and the 7 km Extended Danger Zone on the southeast flank of the volcano remain off-limits due to the threat from sudden explosions and rock fall from the upper slopes.
