New title: Super Typhoon Ragasa Devastates East Asia, Causing Deaths and Mass Evacuations
New description: Super Typhoon Ragasa, one of the strongest storms recorded in 2025, struck Taiwan on September 23, killing at least 14 people and leaving 124 missing after a lake barrier burst in Hualien county, flooding homes and causing widespread destruction including a decades-old lake barrier eruption that residents described as a volcano. The storm then moved to the Philippines, causing additional deaths, before hitting Hong Kong on September 24 with fierce winds, heavy rain, and flooding that closed schools, businesses, and disrupted flights in Hong Kong, Guangdong, and Macau. Over two million people were evacuated in southern China, particularly in Guangdong province, where one million residents were ordered to leave as the typhoon barreled toward the coast, leading to deserted streets and preparations for powerful winds and rain. At least 17 deaths were reported across Taiwan and the Philippines by September 24, with the storm continuing its path into mainland China, marking it as the strongest global storm of the year so far.
