Mayon Volcano - Monitoring Mayon

Monitoring Mayon

Mayon Volcano is the most active volcano in the Philippines, and its activity is regularly monitored by PHIVOLCS from their provincial headquarters on Lignon Hill, about 10 kilometres (6.2 mi) SSE from the summit.

Three telemetric units are installed on Mayon's slopes, which send information to the seven seismometers in different locations around the volcano. These instruments relay data to the Lignon Hill observatory and the PHIVOLCS central headquarters on the University of the Philippines Diliman campus.

PHIVOLCS also deploys electronic distance meters (EDMs), precise leveling benchmarks, and portable fly spectrometers to monitor the volcano's daily activity.
