Hazel Park, MI: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Hazel Park is 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 Hazel Park sits at the 29th percentile for seismic hazard among 4,875 US cities.

Hazel Park by the numbers

The raw figures: peak ground acceleration 0.048g, short-period spectral response 0.097g, 1-second spectral response 0.045g. Among 153 Michigan cities in this dataset, Hazel Park ranks 63 for seismic hazard, the 59th percentile within the state. About 15,064 people live in Hazel Park, Michigan.

Earthquake insurance for a Hazel Park 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 Hazel Park address.
