when is the last time mayon volcano erupted
January 25, 2018
title: Mayon text: The eruptions had an interval of 3 to 5 hours. Classes still remained suspended in some places in Albay. Alert Level 4 was maintained at the volcano for the rest of January and all throughout the month of February as it remained restive. On March 6, 2018, after observing a decline in volcanic activity, PHIVOLCS-DOST downgraded the alert level back to Alert Level 3. On March 29, 2018, after observing a further decline in activity, PHIVOLCS-DOST lowered the alert level back to Alert Level 2 signifying the end of Mayon's eruptive activity and the volcano's decline to a moderate level title: Mayon text: steam plumes drifted to the south-southwest and rain clouds covered the summit. Sulfur dioxide (SO) emission was measured at an 757 tonnes after a peak of 2,360 tonnes on September 6. Ground deformation (precise leveling and tilt meters) during the 3rd week of August 2014 recorded edifice inflation. On January 13, 2018, at 4:21 PM (PST), a phreatic eruption occurred that propelled a grayish steam and ash plume approximately 2500 meters high that drifted to the southwest side of the volcano. The activity lasted approximately 1 hour and 47 minutes and traces of ash fell in Barangay Anoling, Daraga, Barangays title: Mayon text: supplies provided by the DSWD, with more allocated from emergency food stocks intended for relief from the effects of the 2009 Pacific typhoon season. When the alert level was downgraded to level 3 on January 2, 2010, UN-WFP provided three days worth of food for evacuees returning to their homes who will continue to receive supplies already set aside for them. On May 7, 2013, at 8 a.m. (PST), the volcano produced a surprise phreatic eruption lasting 73 seconds. Ash, steam and rock were produced during this eruption. Ash clouds reached 500 meters above the volcano's summit and drifted west title: Mayon text: When an oceanic plate subducts, it releases water into the overlying mantle. The water lowers the melting point of the mantle and triggers melting that generates magma. The magma rises and erupts at the surface at a volcano like Mayon. Mayon is the most active volcano in the Philippines, erupting over 47 times in the past 500 years. The first eruption for which an extended account exists was the six-day event of July 20, 1766. The most destructive eruption of Mayon occurred on February 1, 1814 (VEI=4). Lava flowed but less than the 1766 eruption. The volcano belched dark ash title: Mayon text: signs of abnormal activity were observed before the explosion. Mayon's 48th modern-era eruption was on July 13, 2006, followed by quiet effusion of lava that started on July 14, 2006. Nearly 40,000 people were evacuated from the danger zone on the southeast flank of the volcano. After an ash explosion of September 1, 2006, a general decline in the overall activity of Mayon was established. The decrease in key parameters such as seismicity, sulfur dioxide emission rates and ground inflation all indicated a waning condition. The slowdown in the eruptive activity was also evident from the decrease in intensity of
