The United States Saw 11 Natural Disaster Events That Exceeded $1 Billion in Damage During 2018

By Howard Botts Natural Hazard, Real Estate

When it comes to natural disasters, 2018 was an eventful year worldwide. Wildfires scorched the West Coast of the United States; Hurricanes Michael and Florence battered the Gulf and East Coast. Typhoons and cyclones alike devastated . Earthquakes caused mass casualties in Indonesia, business interruption in Japan and structure damage in Alaska. Volcanoes made the news in Hawaii, expanding the island’s terrain.

1,000-year flood events (or floods that are said statistically to have a 1 in 1,000 chance of occurring) took place in Maryland, North Carolina, South Carolina, Texas and Wisconsin once again. Severe convective storms pelted Dallas, Texas, and Colorado Springs, Colorado, with large hail while a rash of tornado outbreaks, spawning 82 tornadoes in total, occurred from Western Louisiana and Arkansas all the way down to Southern Florida and up to Western Virginia.

According to the National Oceanic and Atmospheric Administration (NOAA)[1], there were 11 weather and climate disaster events with losses exceeding $1 billion in the U.S. alone. Although last year’s count of billion-dollar events is a decrease from the previous year, both 2017 and 2018 have tracked far above the 1980-2017 annual average of $6 billion in total dollar amount in one year.

Annually, CoreLogic takes stock of the events that impacted homeowners and businesses from the financial devastation that often follows catastrophe.

National Flood Event

Highlights from the analysis this year include:

  • In 2018, there were over 1,600 significant flood events that occurred in the U.S., 59 percent of which were flash flood-related.
  • Residential and commercial flood damage in North Carolina, South Carolina and Virginia from Hurricane Florence is estimated at $19 billion to $28.5 billion, of which roughly 85 percent of residential flood losses was in fact, uninsured.
  • The 2018 Atlantic Hurricane season saw 15 named storms, eight of which were named Two of these, Hurricanes Florence (Category 1) and Michael (Category 4), made landfall along the U.S. This made 2018 the third back-to-back season of above-average hurricane activity in the Atlantic.
  • The number of acres that burned in 2018 is the eighth highest in U.S. history as reported through November 30, 2018.
  • A total of 11 western states had at least one wildfire that exceeded 50,000 burned acres; the leading states were California and Oregon, each with seven fires that burned more than 50,000 acres.

No one can stop a hurricane in its tracks or steady the ground from an earthquake, but with more information and an understanding of the risk, recovery can be accelerated and resiliency can be attained. This assessment covers an analysis of what the risk and exposure looked like, what happened during the event and the residential and commercial losses which occurred in the aftermath for each notable climatological event.
