The overall financial toll from each of hurricanes Irma and Maria are expected to be in the tens of billions of dollars, Aon Benfield's Impact Forecasting said in its latest global catastrophe report.
Irma, the first Category 4 hurricane to make landfall in Florida since 2004, left at least 124 people dead or missing in the U.S. and Caribbean. At least 78 people died and many others went missing after Maria ravaged parts of the Caribbean and made landfall on Puerto Rico as a Category 4 storm.
Public and private insurers in both cases face payouts exceeding $10 billion, the report said.
Three powerful earthquakes hit Mexico in September. A magnitude 7.1 earthquake that struck central Mexico killed at least 367 people and injured thousands more. A magnitude 8.1 earthquake that struck offshore from the state of Chiapas, and its magnitude 6.2 aftershock, left at least 103 people dead. The total damage was worth billions of dollars.
Typhoon Doksuri, which hit Vietnam, the Philippines, southern China and Laos, killed 40 people and damaged nearly 250,000 homes. Total economic losses were estimated at $500 million.
Flash flooding in parts of Italy and Croatia killed at least nine people, causing damage of $250 million in Italy and $160 million in Croatia. Flooding also caused $481 million in economic damage in China.
