Boston, Oct. 22, 2019 (GLOBE NEWSWIRE) -- Catastrophe risk modeling firm AIR Worldwide estimates that industry insured losses from Typhoon Hagibis, which made landfall in Japan on October 12, will be between JPY 865 billion (USD 8 billion) and JPY 1,730 billion (USD 16 billion), with more than half of the losses due to inland flooding. AIR Worldwide is a Verisk (Nasdaq:VRSK) business.
According to AIR, Typhoon Hagibis made landfall with 1-minute sustained wind speeds of about 145 km/h (90 mph), the equivalent of a Category 1 hurricane, on the main Japanese island of Honshu on Saturday, October 12, near Shizuoka on the Izu Peninsula. The storm delivered high winds and record-breaking precipitation to a large portion of Honshu from Mie Prefecture in the west to Iwate in the north. Storm surge raised sea levels by more than 1 meter above mean sea level along parts of the coast.
The Japan Meteorological Agency (JMA) issued its Level 5, or highest level, special warning for heavy rain; unprecedented rainfall followed. A wide swath of Honshu just outside the Tokyo metro area received between 250 mm and 500+ mm (10 and 20+ inches) of rain; the resort town of Hakone, where 939.5 mm (37 inches) of precipitation was recorded, broke the calendar-day rainfall record for all of Japan. Hakone’s rainfall represents the second-heaviest 24-hour rainfall ever recorded in Japan—25 inches (635 mm) of the 37 inches fell in just 12 hours. Many regions received between 30% and 40% of their yearly rainfall in just two days, with more than 100 stations breaking daily rainfall records at those locations. As a result of the large swath of unprecedented rainfall in Honshu, numerous rivers—the Abukuma, Arakawa, Chikuma, Kuji, Naka, Shinano, Tone, and Watarase rivers among them—experienced severe and devastating flooding.
According to AIR, of the ~540 river gauging stations on Honshu island, more than 85 exceeded their 100-year return period peak flows, with more than 100 exceeding their historical records. In addition, shortly before Hagibis made landfall, a magnitude 5.7 earthquake struck the region—parts of which were in the early stages of recovery from Typhoon Faxai, which struck just one month prior.
Much of central and eastern Japan experienced severe flooding and landslides; power outages and travel disruption were widespread.
Because of the intense rainfall within a short time period, much of the floodwater has a high mud content and includes a large amount of debris; this could potentially increase the costs of repair and cleanup and drive up business interruption losses—especially for commercial and industrial properties. In addition, Hagibis impacted some of the same region damaged by Typhoon Faxai a few weeks earlier. Additional damage caused by Hagibis to properties that were damaged by Faxai but were not repaired would further complicate claims settlements.
AIR’s modeled insured loss estimates include:
- Insured damage to property (residential, commercial, industrial, and agricultural/mutual), structures and their contents, as well as extra expenses and debris removal, and automobile from wind, storm surge, and inland flood.
AIR’s modeled insured loss estimates do not include:
- Losses from tornado or earthquake
- Losses to land
- Losses to infrastructure
- Losses to CAR/EAR, marine hull, or marine cargo lines of business
- Business interruption losses
- Loss adjustment expenses
- Demand surge—the increase in costs of materials, services, and labor due to increased demand following a catastrophic event; demand surge can be applied by AIR software users who want to account for this variable
