Typhoon Ragasa (also called Nando) roared through the Luzon Strait between September 21 and 22, 2025 before making landfall over China on September 24. As Ragasa passed between Taiwan (north) and the northern Philippines (south), it rapidly intensified to become a super typhoon carrying maximum sustained winds of 165 miles per hour (265.5 km/h). This made it the strongest typhoon this year and second-strongest Super Typhoon in the South China Sea region since Hong Kong’s observatory began to keep records in 1950.
At the same time as about 2 million people evacuated in Guangdong Province China as Ragasa approached landfall, the storm’s brutal winds and torrential rain devastated parts of Taiwan and the Philippines despite passing offshore of both. In the Philippines, ReliefWeb reported the passage of the typhoon resulted in 11 fatalities, more than 690,000 people impacted and at $11,000 displaced.
As of September 26, at least 17 people were killed in Taiwan following overflow of a dam in Hualien County, according to ReliefWeb. Media reported as many as 30 additional people missing and several injured as well as widespread flooding, landslides, and damage to crops and livestock.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired two false-color images, one on September 25 and the other on September 15, that can be compared to visualize the extent of flooding in Taiwan after the passage of Super Typhoon Ragasa. This type of image is used to visually separate water (blue) from vegetation (bright green) and open land (tan). Clouds usually appear as white but high, cold clouds that contain ice may be tinted with light electric blue.
