Typhoon Hagibis to Cost Japan’s Economy $10B, with Insured Losses in Billions: Aon

Typhoon Hagibis is likely to become one of 2019’s costliest events, with economic costs of more than US$10 billion and insured losses minimally in the billions, according to Aon’s monthly catastrophe report.

The storm made landfall in Japan’s Iza Peninsula on Oct. 12 before it swept through the greater Tokyo metro region. At least 95 people were killed, and more than 93,250 structures were damaged or destroyed, said Aon’s Global Catastrophe Recap October 2019 report, which is compiled by Aon’s catastrophe modeling team, Impact Forecasting.

The report then went on to detail the losses from the wildfires that raged in California during the month, exacerbated by strong Diablo & Santa Ana winds, although their impact was less than 2017/18 fires.

California’s most destructive fires during the period Oct. 10-17 included the Saddle Ridge Fire (Los Angeles County) and Sandalwood Fire (Riverside County), which are expected to bring economic damage in excess of US$100 million, with most of the losses covered by insurance.

Extremely critical wildfire conditions also brought numerous ignitions across Northern and Southern California from Oct. 23 into early November, said the report. The most significant fires included the Kincade Fire in Sonoma County with 374 structures destroyed; the Tick Fire in Los Angeles County with 29 structures affected; the Getty Fire in Los Angeles County with 10; the Hillside Fire in San Bernardino County with six; the Maria Fire in Ventura County with four, and the Easy Fire in Ventura County with two structures destroyed. Total economic and insured losses were expected to reach into the hundreds of millions of dollars, the report said.

Also in the U.S. during October, a severe weather outbreak spawned nearly 30 tornado touchdowns, damaging winds, and large hail across the Plains and Southeast on Oct. 20-21 when at least four people were killed. Most impacts were recorded in Texas, where a confirmed EF3 tornado with up to 140 mph (220 kph) winds struck several neighborhoods in North Dallas. Further tornado and storm-related impacts were cited in parts of Arkansas, Oklahoma, Missouri, Louisiana, and Tennessee. Economic and insured losses were likely to reach into the hundreds of millions of dollars, perhaps higher.

“Vulnerabilities around tropical cyclones, flooding, and wildfires were again exposed during October. Events such as Typhoon Hagibis in Japan and wildfires in California served as a reminder of the repetitive, or clustering, nature of certain perils on a year-to-year basis that can often be hard to predict,” said Steve Bowen, director and meteorologist within Aon’s Impact Forecasting team.

“With ample exposure located in high-risk locations all around the world, it becomes increasingly important to utilize the latest tools available to better prepare for future weather and climate-related scenarios in both mature and developing markets,” he added.
