Nationally, Lindenhurst ranks above 29% of the 4,875 cities in this dataset for seismic hazard - the 29th percentile.

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 Lindenhurst address.
