Here is a look back at the CAT-i articles from October 1 through December.
Mw 7.0 Earthquake – Near Anchorage, Alaska: The magnitude (Mw) 7.0 earthquake near Anchorage, Alaska, on November 30 occurred at a depth of 44.1 km as the result of a slip on an intraslab fault within the subducting Pacific slab. According to the United States Geological Survey, the faulting involved a moderately dipping fault striking north-south, below the shallower thrust-faulting interface between the Pacific Plate and the North America Plate. A tsunami warning was issued but later lifted by the U.S. National Weather Service. Damage was reported to buildings, including interior damage and some cracked foundations with some building collapses.
California Wildfire Activity: November Wildfire activity in California rendered especially severe impacts in Northern and Southern California, including areas of Butte, Los Angeles and Ventura Counties. Rates of extreme fire spread were enabled by especially dry, windy conditions on November 8 and the days following. Aggressive firefighting efforts allowed containment efforts to progress despite adverse conditions. Camp, Woolsey and Hill Fires burned an estimated 20,297 structures since November 8, including at least 13,972 residential structures from the Camp Fire alone, according to Cal Fire statistics (as reported in the CAT-i on November 29). These fires have also claimed at least 91 lives. Media reports indicate estimated insured losses for the Camp and Woolsey Fires of around USD 9-13 billion as reported by RMS.
Hurricane Michael: Hurricane Michael, the strongest hurricane to affect the Continental U.S. since Hurricane Andrew in 1992, made landfall on October 10 as a high-end Category-4 hurricane on the Florida Panhandle, with maximum sustained winds of 155 mph. The storm rendered severe to complete damage to areas from Panama City to Port Saint Joe, with especially severe damage in Mexico Beach due to severe wind and storm surge. Wind caused roof and wall collapse, especially for cinderblock construction and even commercial properties. Some coastal areas of Mexico Beach were scoured to the foundation by storm surge and wave battering. At least 12 fatalities were reported by media by the time the CAT-i was released.
Super Typhoon Trami: In the West-Pacific Basin, Typhoon Trami made landfall in the city of Tanabe, Japan (Wakayama prefecture) on 30 September, according to media reports. Before reaching Honshu, the typhoon had rendered considerable impacts while making close approach to Okinawa, Kyūshū and Shikoku Islands. Trami brought significant flood impacts as a result of heavy rainfall and storm surge, as well as variable property damage due to wind. Significant power outages and transportation disruption were reported by media. Over 4.3 million people were given evacuation orders or advisories. Media reports indicated at least four fatalities and 120 injured.
