Ilion, NY: what USGS's seismic model says

USGS's ASCE 7-16 seismic design model - the same standard building codes use - places Ilion in Seismic Design Category B: Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Ilion ranks above 55% of the 4,875 cities in this dataset for seismic hazard - the 55th percentile.

Where Ilion sits in New York

USGS's underlying values for Ilion: 0.096g peak ground acceleration, 0.182g at short period, 0.058g at 1 second. Within New York alone, Ilion ranks 117 of 170 cities by seismic hazard - the 31th percentile in-state. Ilion has a population of about 7,559.

Retrofit economics for Ilion

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 New York 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 New York.

Insuring against this, not just retrofitting

A Ilion 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 Ilion's figures come from

Ilion'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 Ilion.
