Latrobe, PA: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Latrobe in Seismic Design Category B: 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 Latrobe sits at the 22th percentile for seismic hazard among 4,875 US cities.

Where Latrobe sits in Pennsylvania

USGS's underlying values for Latrobe: 0.042g peak ground acceleration, 0.088g at short period, 0.044g at 1 second. Within Pennsylvania alone, Latrobe ranks 155 of 193 cities by seismic hazard - the 20th percentile in-state. Latrobe has a population of about 7,906.

Retrofit economics for Latrobe

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 Pennsylvania 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 Pennsylvania.

Insuring against this, not just retrofitting

A Latrobe 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 Latrobe's figures come from

Latrobe'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 Latrobe.
