MANILA, Philippines, Dec. 26 (UPI) — Scientists monitoring the Mayon volcano in the Philippines say a recent lull in activity could be the calm before the storm of a major eruption.
Vulcanologist Ed Laguerta said previous eruption records of Mount Mayon keeps officials from recommending a return home for more than 47,000 evacuees, the Manila Bulletin reported Saturday.
“We already learned our lesson in the past,” said Laguerta. “Every affected resident here knows that the silence of Mayon is not an assurance that they would be safe if they go back home.”
Along with previous records, scientists are relying on monitoring instruments placed around the volcano following days of rumblings and ash clouds.
There has been a significant increase in sulfur dioxide emissions, Laguerta said, from nearly 2,000 tons Thursday to nearly 9,000 tons a day.
“So we cannot say at this point that it is already safe for evacuees to go back home, we still have to monitor and monitor,” he said.
