Mayon (Central Bikol: Bulkan Mayon; Tagalog: Bulkang Mayon, IPA: [mɐjɔn]), also known as Mount Mayon and Mayon Volcano (Spanish: Monte Mayón, Volcán Mayón), is an active stratovolcano in the province of Albay in Bicol Region, on the island of Luzon in the Philippines. A popular tourist spot, it is renowned for its 'perfect cone' because of its symmetric conical shape, and is regarded as very sacred in Philippine mythology.The volcano with its surrounding landscape was declared a national park on July 20, 1938, the first in the nation. It was reclassified as a natural park and renamed the Mayon Volcano Natural Park in 2000. It is the centerpiece of the Albay Biosphere Reserve, declared by UNESCO in 2016, and is currently being nominated as a World Heritage Site. Mayon is the most active volcano in the Philippines, and its activity is regularly monitored by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) from their provincial headquarters on Ligñon Hill, about 12 kilometers (7.5 mi) from the summit.

On March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place on May 18, 1980. The eruption, which had a Volcanic Explosivity Index of 5, was the most significant to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. It has often been declared the most disastrous volcanic eruption in U.S. history. The eruption was preceded by a two-month series of earthquakes and steam-venting episodes caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain's north slope. An earthquake at 8:32:11 am PDT (UTC−7) on Sunday, May 18, 1980 caused the entire weakened north face to slide away, creating the largest landslide in recorded history. This allowed the partly molten rock, rich in high-pressure gas and steam, to suddenly explode northward toward Spirit Lake in a hot mix of lava and pulverized older rock, overtaking the landslide. An eruption column rose 80,000 feet (24 km; 15 mi) into the atmosphere and deposited ash in 11 U.S. states and two Canadian provinces. At the same time, snow, ice, and several entire glaciers on the volcano melted, forming a series of large lahars (volcanic mudslides) that reached as far as the Columbia River, nearly 50 miles (80 km) to the southwest. Less severe outbursts continued into the next day, only to be followed by other large, but not as destructive, eruptions later that year. Thermal energy released during the eruption was equal to 26 megatons of TNT.About 57 people were killed, including innkeeper and World War I veteran Harry R. Truman, photographers Reid Blackburn and Robert Landsburg, and geologist David A. Johnston. Hundreds of square miles were reduced to wasteland, causing over $1 billion in damage (equivalent to $3.5 billion in 2020), thousands of animals were killed, and Mount St. Helens was left with a crater on its north side. At the time of the eruption, the summit of the volcano was owned by the Burlington Northern Railroad, but afterward, the railroad donated the land to the United States Forest Service. The area was later preserved in the Mount St. Helens National Volcanic Monument.
