Vernon, TX: what USGS's seismic model says

Vernon carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Vernon sits at the 46th percentile for seismic hazard among 4,875 US cities.

How Vernon compares

USGS's underlying values for Vernon: 0.071g peak ground acceleration, 0.141g at short period, 0.055g at 1 second. Within Texas alone, Vernon ranks 23 of 384 cities by seismic hazard - the 94th percentile in-state. Vernon has a population of about 9,728.

Bracing and bolting: the actual cost

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 Vernon home

A Vernon 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.
