Your go-to for catastrophe response

Between the wildfires that have been blazing across the United States and hurricane season brewing in the Atlantic basin, 2018 is shaping up to be a busy year. We know things tend to speed up when catastrophes occur, so we want to make sure you’re finding all the information you need to be up to date in one place.

Here you’ll find press releases, explanations of how our data works, and commentary about what kind of damage we foresee based on the particular hazard—be it a hurricane, volcano, earthquake, or beyond.

[NEW] 2018 Wildfire Season Outpacing 2017

Less than a year ago, California was ablaze with some of the most catastrophic fires the United States has seen. Over 10 million acres burned, and many homes and lives were lost. Seven months later, and wildland fires have again made the news in California and nationally.

  • The reconstruction cost value (RCV) of a catastrophe. This includes the cost of the parts, labor demand, and even factors in regional pricing differences to come to a sum of what it would take to reconstruct a property. This does not have any relation to housing prices.
  • The loss of any natural hazard—the insured portion that will be paid through to recover.
  • The damage in dollars associated with the disaster, both insured and uninsured.

[Blog] The Impact of Getting ITV Wrong

Most people understand that the goal of a homeowner’ policy is to restore a home and possessions to the way they were should a natural or not-so natural disaster strike. If the coverage is too low, the homeowner may not have enough to fully cover the losses incurred.

Number Soup

We know that data can get confusing, especially as we begin to put out estimates for reconstruction cost and damage in response to any hazard event.

To help shed some light on a chaotic time, we wanted to help answer some frequently asked questions.

Frequently Asked Questions

CoreLogic uses its RCV methodology which estimates the cost to rebuild the home in the event of a total loss and is not to be confused with property market values or new construction cost estimation. Reconstruction cost estimates more accurately reflect the actual cost of damage or destruction of residential buildings that would occur from hurricane-driven storm surge, since they include the cost of materials, equipment and labor needed to rebuild. These estimates also factor in geographical pricing differences (although actual land values are not included in the estimates).

Damage is the overall sum of money lost, both insured and uninsured. 

Loss, otherwise known as gross loss or ground-up damage, is the insured portion of the damage sum. It is the portion that insurance companies pay out.

This issue mostly happens with hurricanes as there’s some level of foresight to put out advance notice on numbers.

The costs associated with a hurricane have more to do with the size and the location of the storm. Early on, there are a variety of projected paths of where a storm can go, so we can’t be as certain about the scope of the damage.

It is important to consider a strong hurricane that occurs in a less densely populated area – or even a small storm that tracks through a densely populated area – could generate catastrophic storm surge. When evaluating potential damage, the number of storms that occur is not as significant as the intensity and track of where they occur. As we get closer to landfall, we can have more confidence in the dollar values associated with the storm.

However, numbers can also change for other non-tropical cyclonic phenomena. In the same way, we can be more confident in the precision of our data and its accuracy as we learn more about the event. The better the data over time, the more precise our numbers can be.

At CoreLogic, we break down the risk of damage cumulatively. If any hurricane hits, no matter the Category*, it will cause storm surge in the Extreme risk areas. These are homes that typically are closest to the coast and lowest in elevation, thus susceptible to every type of hurricane from Categories 1 to 5. Therefore, their risk of impact is Extreme.

Similarly, the strongest Category 5 hurricane will cause storm surge induced flooding furthest inland. It is listed in the table as Low risk because these hurricanes are the least likely to incur damage, not because they do less damage. However, because a Category 5 hurricane will also cause damage at more vulnerable properties, the cumulative amount of homes affected and the total RCV both increase. These hurricanes affect the same areas that weaker hurricanes do and more.

*Categories are measured on the Saffir-Simpson Hurricane Wind Scale (SSHWS).

In order to develop an estimate about the rainfall, we first need a footprint of where we think the rain is going to fall, and we won’t know that until the storm is conclusive about where it’s going to make landfall and where that path will take it.

The short answer is…nothing. CoreLogic is a real estate and data analytics company. We don’t make predictions, and we’re not going to be able to tell you whether to stock up on water or canned goods or sweaters or sand bags like a weather man will.

What we can provide is a realistic assessment of how a catastrophe impacts people—their homes and businesses—and what that will look like, both insured and uninsured. We are able to do this with both our highly granular catastrophe models to determine the impact upon properties and with a team of Ph.D.-level scientists who work hard to Get The Whole Story.

Cat Repository

Here’s where you’ll find notable archived content of natural hazards in reverse chronological order. 2017 was a record-breaking year, with the first continental U.S. landfall since Hurricane Wilma in 2005. Harvey, Irma, Maria, and Nate brought their own forms of chaos, from storm surge, inland flooding, and devastating winds, causing significant damage and disruption to the lives and livelihoods in the impacted areas.

In addition, 10 million acres were burned away in horrific wildfires, and then before that, cities pummeled by hail.

Below is a summary of what we've covered. If you need to find anything not listed below, please contact Alyson Austin at or Caitlin New at

California Wildfires

Multiple record-setting fires occurred in late 2017 in both northern and southern California. There were more fires in 2017 than in any of the previous 10 years combined, and the Diablo and Santa Ana winds contributed heavily to record setting destruction. By the time all was said and done, over 10 million acres had been burned.

The Wildfire Risk Score was used to assess the quantity of structures in the area at greater risk.

Hurricane Nate was the 14th named storm and ninth hurricane of the 2017 Atlantic Hurricane season. As a Category 1 fast-moving storm, it moved through Nicaragua, Honduras, and later on after gaining strength, made landfall at the Mississippi River delta near Blioxi on October 8.

Property damage from Hurricane Nate was estimated to be between $650 million and $1.35 billion, of which an estimate $500 million to $1 billion of insured loss was attributed to wind property damage.

Hurricane Maria was the 13th named storm and fourth major hurricane of the 2017 Atlantic Hurricane season. Hurricane Maria made landfall on September 20 as a strong Category 4 hurricane. The southeast corner and some beach areas of San Juan, Puerto Rico, saw the strongest winds while the entire island saw at least tropical storm force winds.

Property damage from the wind and rain was estimated to be between $20 billion and $25 billion.

Hurricane Irma was a Category 4 storm that made landfall in South Florida, causing an estimated $14 billion to $19 billion in losses. The track off Hurricane Irma exposed millions of homes to winds at tropical storm force or greater, of which around 175,000 were exposed to extreme winds exceeding 125mph.

To glean more information about the storm, CoreLogic worked with our property data to inventory the homes at risk in Florida with tools such as Storm Surge Risk, Wind Risk, and Flood Risk. These help to determine the dollar value and property count at stake.

Hurricane Harvey was the first landfalling storm in the United States since Hurricane Wilma in 2005. Prior to 2017, Hurricane Katrina represented the most severe hurricane impacting the mainland U.S.

CoreLogic inventoried every property at risk of damage using the Storm Surge Risk Score to determine the amount of home at risk of being impacted by tidal damage. We also utilized our Flood Risk Score to do the same to assess risk in various counties.

Irma Press Releases

CoreLogic® (NYSE: CLGX), a leading global property information, analytics and data-enabled solutions provider, today released data analysis which shows that an estimated 8,456,455 residential and commercial properties in Florida are at either “Extreme,” “Very High” or “High” risk of wind damage from Hurricane Irma.

According to the data analysis, total insured and uninsured loss for both residential and commercial properties, including damage from both flood and wind, is estimated to be between $42.5 billion and $65 billion.* Of this, an estimated $13.5 billion to $19 billion in insured loss is attributed to damage from wind for both residential and commercial properties.

Harvey Press Releases

Hazard HQ

According to the data analysis, insured flood loss for homes in the 70-county area in Texas and Louisiana affected by the storm is estimated to be between $6.5 billion and $9.5 billion, which includes inland, flash and storm surge flooding…

Hazard HQ

This analysis shows that 52 percent of residential and commercial properties in the Houston metro are at “High” or “Moderate” risk of flooding, but are not in a Special Flood Hazard Area (SFHA) as identified by the Federal Emergency Management Agency (FEMA).

Hazard HQ

CoreLogic® (NYSE: CLGX), a leading global property information, analytics and data-enabled solutions provider, has conducted an analysis which shows that insured property losses for both residential and commercial properties from Hurricane Harvey are estimated to be between $1 billion and $2 billion from wind and storm surge damage.

Hazard HQ

According to CoreLogic data analysis, 232,721 homes along the Texas coast with a reconstruction cost value (RCV) of approximately $39.6 billion are at potential risk of hurricane-driven storm surge damage from Hurricane Harvey, based on Category 3 predictions. Current projections do not expect Hurricane Harvey to exceed a Category 3 storm.

Colorado Hail

During rush hour on May 8, a severe thunderstorm dropped up to baseball-sized hail across the Denver, Colorado, metropolitan area. The Rock Mountain Insurance Information Association (RMIIA) estimated losses to be an astonishing $1.4 billion.

With use of the CoreLogic Hail Verification data, we can assess that the severity of hail in 2017 was similar to the prior 3 years but still well below the 2011 high.
