Mayon crater glow intensifies
LEGAZPI CITY, Philippines – An aerial survey to find out if magma is moving upwards toward the summit of Mayon volcano was conducted yesterday morning, as crater glow has intensified, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
“We want to find out whether there are visible changes in the volcano, so we can have an overall picture of Mayon volcano,” said Ed Laguerta, Phivolcs resident volcanologist.
Laguerta said six volcanic quakes have been detected during the past 24 hours and the volcano’s crater glow, which is visible during clear nights, has intensified, while a ground deformation survey has detected an inflation at the volcano’s edifice at 10 millimeters since last month.
“The inflation tends to show that magma at a lower level is rising towards the crater, which is the reason for the intensification of the crater glow. This means that very hot gas is supplying the glow reflected on the volcano’s summit,” he said.
