MANILA, Feb. 23 (Xinhuanet) -- Nine volcanic earthquakes were recorded on Thursday in Mayon volcano in Albay, 330 km south east to Manila, according to the Philippine Institute of Volcanology and Seismology (PHIVOLCS)

    PHIVOLCS director Renato Solidum said in an interview that the agency recorded two minor explosions in the area Thursday morning and observed some small lava flows from Mayon's crater.

    Alert level 2 has been declared Tuesday by the agency to make sure nobody enters the six-km danger zone around the Mayon Volcano.

    Although PHIVOLCS has not increased the warning to level 3, Solidum said the agency is closely monitoring the volcano.

    Solidum said the tests have yet to ascertain if the Mayon would erupt again.

    The Mayon is the most active volcano in the country, having erupted around 50 times for the past 400 years. Its last eruption was in July 2001. Enditem
