MAYON VOLCANO BULLETIN 24 June 2018 08:00 A.M.
Alert Level 2 currently prevails over Mayon Volcano - moderate level of unrest. 
  1. Mayon Volcano’s seismic monitoring network did not detect any volcanic earthquake during the past 24 hours.
  2. Moderate to voluminous emission of white steam-laden plumes that rose 500 to 1000 meters from the summit that drifted west-northwest to northwest was observed lately. 
  3. Fair crater glow from the summit could be observed at night. 
  4. Sulfur dioxide (SO2) emission was measured at an average of 1287 tonnes/day on 20 June 2018. Precise leveling data obtained on 02-14 April 2018 indicate inflation of the edifice relative to 22-29 March 2018, while electronic tilt data show sudden slight inflation of the mid-slopes beginning 05 May 2018. 
  5. Medium-term ground deformation data, however, show that the edifice is still deflating consistent with the decline in unrest but is still inflated relative to 2010 baselines.
  6. DOST-PHIVOLCS recommends that entry into the six kilometer-radius Permanent Danger Zone or PDZ and a precautionary seven kilometer-radius Extended Danger Zone or EDZ in the south-southwest to east-northeast sector, stretching from Anoling, Camalig to Sta. Misericordia, Sto. Domingo must be strictly prohibited. People residing close to these danger areas are also advised to observe precautions associated with rockfalls, PDCs and ashfall.
