The ruins were unharmed even as the typhoon devastated the surrounding countryside with mudslides and lahar that killed at least 1,266 people. [18] [19] The incident is similar to another catastrophe in the same region in 1825, shortly after the 1814 Mayon eruption. [7]
Mayon is shared by eight cities and municipalities of Albay province.. Mayon is the main landmark and highest point of the province of Albay and the whole Bicol Region in the Philippines, rising 2,463 meters (8,081 ft) from the shores of Albay Gulf about 10 kilometers (6.2 mi) away.
Within 21 minutes, the lahars descended Mayon Volcano, quickly covering and wrecking six communities. After the initial series of lahars, further ash flow descended to the ocean to the north of Mayon Volcano. [40] Areas around the volcano were inundated with 1.5 m (5 ft) of floodwaters. [46] Widespread flooding was also reported in Legazpi City ...
In 1991, damage to crops and property was estimated at $374 million (or $711 million today), to which continuing lahar floods added a further $69 million (or $127 million today) in 1992. In total, 42 percent of the cropland around the volcano was affected by more lahar floods, dealing a severe blow to the agricultural economy in the region. [21]
Typhoon Durian (Reming, 2006) – a typhoon which caused devastating lahar flows from the Mayon Volcano. Tropical Storm Fung-wong (Mario, 2014) – another tropical system that caused lahar flows from the Mayon Volcano. Typhoon Vongfong (Ambo, 2020) – a typhoon which took a relatively similar path to Yunya.
Pyroclastic flows sweep down the flanks of Mayon Volcano, Philippines, in 2018. A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) [1] is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of 100 km/h (30 m/s; 60 mph) but is capable of reaching speeds up to ...
Amid rain from Tropical Storm Fung-wong, lahar flowed in Albay from Mayon Volcano. [18] Possible landslides were possible within the area due to 22 volcanic earthquakes and 77 rockfall events. NDRRMC warned residents to prepare and evacuate in the areas within the 6 km Radius Permanent Danger Zone.
Early predictions led to the evacuation of tens of thousands of people, saving many lives. The eruption severely damaged surrounding areas with pyroclastic surges, pyroclastic falls, and later, flooding lahars caused by rainwater re-mobilizing volcanic deposits. This destruction affected infrastructure and altered river systems for years.
