Kumamoto quake insured losses may reach $2.1B, Verisk says

Verisk Analytics ↘ 0.08% estimated that insured losses from the magnitude 7.1 earthquake that struck Japan's Kumamoto Prefecture on July 28 will range between JPY 220 billion (approximately $1.4 billion) and JPY 340 billion (approximately $2.1 billion), the company's Catastrophe and Risk Solutions group said in a statement released on August 2.globenewswire+1

The assessment covers insured physical damage to residential, commercial, industrial and mutual property risks, including structures and contents, with the losses driven primarily by ground shaking and a smaller contribution from liquefaction. The estimates exclude losses to uninsured properties, infrastructure, automobiles, business interruption, and certain non-modeled perils such as landslide and fire.streetinsider+1

Scale of the Disaster

The earthquake struck near Kumamoto City on Japan's Kyushu Island on the afternoon of July 28, causing widespread destruction. A floor collapsed at an Aeon mall in Kashima Town, trapping dozens of people, and a highway bridge buckled under the force of the tremor. The death toll has risen to at least 38, according to Japanese authorities, with more than 80 people injured.aljazeera+5

Tens of thousands of homes lost electricity in the immediate aftermath, and rail services including bullet trains were suspended across the region. The earthquake triggered a tsunami advisory for waves of up to one meter, though the warning was later lifted.aljazeera

Insurance Industry Impact

Verisk noted that its loss range reflects uncertainty related to fault slip distribution, ground-motion intensity, damage estimation, and earthquake insurance take-up rates in Japan. The estimates are calculated before any recoveries under Japan's earthquake insurance program.streetinsider

The disaster echoes the 2016 Kumamoto earthquakes, which killed 275 people and caused extensive damage in the same region. Kumamoto Prefecture, located on Japan's southern island of Kyushu, remains vulnerable to seismic activity along active fault lines.aljazeera

As rescue and recovery operations continue, the full economic toll is expected to grow once business interruption, infrastructure damage, and other excluded categories are factored in.insurancenews
