November 17, 2023
The southern tip of Mindanao Island faced a magnitude 6.6 earthquake, leading to collapsed houses and landslides. Panic heightened casualties, resulting in 9 deaths and 776 injuries.
Active Volcanoes in the Philippines
The Philippine Islands, nestled within the Pacific Ring of Fire alongside neighbors Indonesia and Japan, boast a collection of over 27 active volcanoes. While many erupt infrequently, these geological marvels have left an indelible mark on the country’s landscape and history. Here, we delve into some of the most currently active volcanoes in the Philippines:
Located in the southern part of Luzon, Mayon Volcano stands as one of the most active and revered volcanoes in the republic. Soaring to a height of 2463 meters, it attracts tourists with its majestic beauty. However, its eruptions, marked by the release of copious ash, have been historically perilous. The eruption in 1897 claimed lives due to steam and ash, prompting subsequent evacuations and restrictive measures during eruptions in this century.
Situated southwest of Luzon Island, Taal Volcano is a picturesque volcanic crater, only 311 meters above sea level. Despite its modest height, Taal’s eruptions have proven deadly over the centuries, claiming over 6,000 lives in the Taal area. The 1911 eruption was particularly impactful, with the explosion’s sound heard 800 kilometers away, and ash covering a vast area. The most recent eruption in January 2022 prompted the evacuation of several thousand people.
Located in the central part of Luzon, Pinatubo is not only a popular trekking destination but also the site of one of the most powerful eruptions in the 20th century. The eruption in August 1991 propelled ash columns 40 kilometers high, lowering the volcano’s height by 200 meters and forming a picturesque caldera turned lake. The devastation included mudflows that swept away towns, resulting in 847 casualties and the urgent evacuation of 20 thousand people. Despite its historic eruption, Pinatubo remains weakly active.
Typhoons, Cyclones, and the Ravages of Floods
The Philippines, nestled in the heart of the typhoon-prone Western Pacific, bears the brunt of at least 10 typhoons annually, with half of them categorized as catastrophic. Originating in the South China Sea and occasionally the Philippine Sea, these tempests pose a recurring threat, particularly during the summer and fall months, with August standing out as the most active period. Here are accounts of some of the most destructive typhoons in recent times:
November 1991, Thelma
Thelma, a tropical storm originating near the island of Palau, became one of the most destructive of the 20th century. Sweeping over the Philippines, it unleashed heavy rains on central islands, causing severe flooding. The town of Ormoc, devastated by powerful downpours, witnessed catastrophic consequences, with nearly 5,000 people losing their lives in just three hours. The overall death toll reached 8,000, and damages amounted to $27 million.
September 2009, Parma
Typhoon Parma, known as Peping in the Philippines, wreaked havoc by passing over Luzon twice, bringing substantial rainfall. The resultant floods swept away houses, destroyed infrastructure, and triggered landslides. Agricultural fields suffered extensive damage. The total estimated damage from the typhoon reached $419 million, with 465 fatalities. A staggering 1,800 millimeters of precipitation fell during this period.
