Typhoon Chanthu, known in the Philippines as Super Typhoon Kiko,[1] was the second most intense tropical cyclone worldwide in 2021 after Typhoon Surigae in April. It impacted the Cagayan Valley region of the Philippines and became the strongest typhoon to affect the Batanes province since Typhoon Meranti in 2016. The twenty-ninth tropical depression, fourteenth named storm and fourth typhoon of the 2021 Pacific typhoon season, Chanthu originated from a disturbance well east of the Philippine islands on September 5 which organized into a tropical depression later that day. By the next day, the depression had formed into a mature tropical storm which began to explosively intensify by September 7, featuring a pinhole eye on satellite, characteristic of rapidly intensifying storms. Chanthu became a Category 5-equivalent super typhoon by September 8, the highest category on the Saffir–Simpson scale. Subsequent eyewall replacement cycles caused intensity fluctuations, but on September 10, Chanthu peaked with 1-minute sustained winds of 285 km/h (180 mph) just northeast of extreme northeastern Luzon. The typhoon passed very near the Babuyan Islands before passing directly over Ivana, Batanes as a weakening but still powerful Category 5-equivalent super typhoon. Chanthu continued steadily weakening as it passed just east of Taiwan and eventually stalled just east of Shanghai, China. The storm eventually made its second and final landfall near Ikitsuki, Nagasaki in Japan, before crossing the country's mountainous terrain and becoming an extratropical cyclone on September 18. Chanthu then continued eastward and curved southward, before dissipating on September 20. According to Aon Benfield, economic losses totaled US$30 million.[2]
