Qatar- Mayon volcano alert level 'may be lowered soon'

(MENAFN- Gulf Times) The Philippine Institute of Volcanology and Seismology (Phivolcs) would lower from three to four the alert level for Mount Mayon in the next few weeks, if the volcano's waning activity continued.
Ed Laguerta, Phivolcs chief volcanologist in the Bicol Region, yesterday said Mayon was showing low abnormal activity in the last 24 hours but no conclusive proof would support that such activity was weakening. Thus, according to Laguerta, Alert Level 4 and the eight-kilometre danger zone stay. He, however, believes that the volcano may still generate explosions as it did in 1984 when Mayon exploded after being quiet for a week.
'We are closely studying the sudden change and decrease of (sulphur dioxide gas emission) of Mayon to 1,583 tonnes per day from the more than 3,000 tonnes two days ago, Laguerta said during a news briefing.
With Alert Level 4 in place, public have been strongly advised to not enter the eight-kilometre danger zone and to be vigilant against pyroclastic currents, lahars and sediment-laden stream flows.
