MANILA, Feb. 3 (Xinhuanet) -- The Philippine Institute of Volcanology and Seismology (PHIVOLCS) reported Thursday that increased seismic activities of Mayon Volcano in central Philippines has been recorded during the past 24 hours as Alert Level 2 remained hoisted over the volcano.
The latest PHIVOLCS bulletin released 8 a.m. Thursday showed that six low
frequency and one high frequency short duration harmonic tremors were registered
by seismic monitors stationed in and around Mayon.
The agency warned residents living near and around the volcano slopes not
to venture into the six-kilometer radius Permanent Danger Zone. PHIVOLCS said
the advisory is strictly enforced on the southeast sector where volcanic flows,
falling and rolling debris may be produced by Mayon.
Also on Thursday PHIVOLCS director Rene Solidum dispatched a team of
geologists and seismologists to Legazpi City south of the Mayon Volcano to
conduct ground deformation surveys around the slopes of Mayon.
The last ground deformation reading was conducted in September last year
when a slight inflation was noted on the slopes of the volcano. Enditem
