Current information flow on the status of Mayon and how this is relayed simultaneously to various groups using multiple channels with PHIVOLCS as the main source. PHIVOLCS as warning agency issues Volcano Alert Levels for specific volcano status thru its Volcano Bulletins or Advisories simultaneously to the Albay Province, Regional (OCD-Region 5) and national-level (National Disaster Risk Reduction Management Council, NDRRMC), based on interpretation of data coming from its network of monitoring instrument maintained and operated by the Mayon Observatory at Lignon Hill in Legaspi City. The local, national and international media has access to this information. Issuances from PHIVOLCS are directly received by the provincial-level disaster office (APSEMO) which in turn still communicates the information officially to the Albay constituents via various local media channels
