LEGAZPI CITY—Low-frequency quakes rocked Mt. Mayon even as its steam emission dropped suddenly, indicating an explosive eruption is highly possible, scientists said yesterday.
The Philippine Institute of Volcanology and Seismology said the low-steam emission indicated gas was being blocked by fresh magma and building pressure in the volcano’s vents.
Seismic instruments detected 51 low-frequency quakes compared with the 16 recorded on Wednesday, indicating the volcano was bringing more magma up to the crater, it said.
The instruments also recorded 343 tremors caused by lava tumbling down the volcano’s slopes.
“The presence of low-frequency volcanic earthquakes triggered by the active degassing and partial blockade of...
