New Martinsville, WV: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places New Martinsville in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, New Martinsville ranks above 28% of the 4,875 cities in this dataset for seismic hazard - the 28th percentile.

New Martinsville by the numbers

USGS's underlying values for New Martinsville: 0.048g peak ground acceleration, 0.099g at short period, 0.051g at 1 second. Within West Virginia alone, New Martinsville ranks 21 of 26 cities by seismic hazard - the 20th percentile in-state. New Martinsville has a population of about 5,038.

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 West Virginia 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 West Virginia.

Insuring against this, not just retrofitting

A New Martinsville 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 New Martinsville's figures come from

New Martinsville's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about New Martinsville.
