Overview
track of Ida

Ida landed near Makurazaki in Kagoshima Prefecture on September 17. [1] Ida was the strongest typhoon to hit Kyushu on record, with a minimum sea-level pressure of 916.1 hPa (27.05 inHg) and a maximum wind gust of 62.7 metres per second (140 mph), which was recorded at a weather station in Makurazaki.[3] 916.1 hPa is the second lowest ever recorded in Japan, after 911.6 hPa recorded during the 1934 Muroto typhoon.[2][1][4]

More than 2,000 people were killed in the Hiroshima Prefecture after heavy rains brought by a weakening Ida caused severe landslides.[5][1][6] At that time, Japan was just after the end of the war, and the damage caused by Ida was serious.[1][6]

In addition, USS Repose (AH-16) reportedly entered Ida's eye and observed an atmospheric pressure of 25.55 inches of mercury (about 856 hPa).[7][8][9] This is below the Typhoon Tip (870 hPa) in 1979, the official world record for minimum sea level pressure.
