Lawrence, KS: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Lawrence is Category B. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Nationally, Lawrence ranks above 27% of the 4,875 cities in this dataset for seismic hazard - the 27th percentile.

Where Lawrence sits in Kansas

The raw figures: peak ground acceleration 0.046g, short-period spectral response 0.096g, 1-second spectral response 0.065g. Among 63 Kansas cities in this dataset, Lawrence ranks 10 for seismic hazard, the 85th percentile within the state. About 97,271 people live in Lawrence, Kansas.

Retrofit economics for Lawrence

Outside California, no state-level retrofit grant equivalent to Brace + Bolt could be found for Kansas. A typical retrofit still runs $5,000-$10,000 nationally, about $7,000 for a common single-family job.

Earthquake insurance for a Lawrence home

Outside California, earthquake coverage is typically sold as an endorsement added to a standard homeowners policy, not a separate product - worth asking about directly when getting a home-insurance quote for a Lawrence address.
