Highland, IN: what USGS's seismic model says
USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Highland in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Highland ranks above 35% of the 4,875 cities in this dataset for seismic hazard - the 35th percentile.
How Highland compares
USGS's underlying values for Highland: 0.058g peak ground acceleration, 0.119g at short period, 0.066g at 1 second. Within Indiana alone, Highland ranks 101 of 126 cities by seismic hazard - the 20th percentile in-state. Highland has a population of about 23,497.
What a retrofit costs in Highland
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 Indiana 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 Indiana.
What this means for insurance
A Highland 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 Highland's figures come from
Highland'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 Highland.
