That puts Argyle in the 33th percentile nationally for seismic hazard - higher than 33% of the 4,875 US cities USGS was checked against here.

Argyle by the numbers

USGS's underlying values for Argyle: 0.055g peak ground acceleration, 0.112g at short period, 0.056g at 1 second. Within Texas alone, Argyle ranks 60 of 384 cities by seismic hazard - the 85th percentile in-state. Argyle has a population of about 6,294.

Retrofit economics for Argyle

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Texas specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Texas.

Earthquake insurance for a Argyle home

A Argyle homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Argyle's figures come from
