• A 4.9 magnitude earthquake, the strongest in Louisiana’s onshore history, struck near Shreveport.
• Standard homeowner’s insurance policies typically do not cover earthquake damage.
• Property owners can purchase add-on earthquake coverage, which is generally inexpensive in low-risk areas like Louisiana.
• Despite the low cost, the deductible for earthquake insurance is usually high.

Thursday’s earthquake that shook furniture and rattled pipes in the Shreveport region may have some property owners wondering whether they should consider buying insurance to cover them from potential stronger movement in the future.

The 4.9 magnitude earthquake that struck just north of Coushatta at 5:30 a.m. March 5 was the strongest onshore event in Louisiana history.

No structural damage has been reported from Thursday’s earthquake so far, but the strength of the movement may have been enough to raise concern.

“If people are concerned they should call their insurance agent and explore pricing and options,” Louisiana Insurance Commissioner Tim Temple said in an interview with USA Today Network.

“It’s not an issue that has come up often in Louisiana, but if coverage can alleviate anxiety and risk it’s absolutely something homeowners and property owners should consult their agent about,” he said.

Earth movement or subsidence insurance is generally excluded from homeowners’ policies, as is flood insurance, but property owners can secure the coverage through their insurers as an add-on, called an endorsement.

Eugene Montgomery, owner of Community Financial Insurance Center in northern Louisiana, said a subsidence endorsement to cover earthquake damage would generally be inexpensive in Louisiana because of the low risk.

“The coverage itself is inexpensive, but the deductible would be high,” Montgomery told USA Today Network.

That’s the case for one Shreveport homeowner who asked not to be identified. The homeowner secured a subsidence endorsement following Thursday’s earthquake that cost $120 per year after discounts with a 10% deductible.

Republican state Sen. Adam Bass, who also operates an Allstate agency in Bossier, said most people won’t buy an add-on that’s not required by their mortgage holders no matter how inexpensive it is.

Bass said he hasn’t had any inquiries about earth movement insurance during his career.

But Montgomery said he remembers a temporary spike in those policies in 1990 when climatologist Iben Brown predicted a major earthquake would strike the New Madrid Fault in Missouri on Dec. 3 of that year, a forecast that flopped.

“It really created a little bit of a panic,” Montgomery said. “Everybody wanted insurance for a short period of time.”

Montgomery doesn’t expect a similar run on earthquake after Thursday’s event, but said he won’t be surprised if some level of interest increases.

“When people can actually feel the earth moving it gets their attention,” he said.
