Tarpon Springs, FL: what USGS's seismic model says

Under the seismic model IBC and ASCE 7 use for new construction, Tarpon Springs is Category A. Lowest seismic design category. Building code requires no seismic-specific detailing here beyond ordinary construction practice. That puts Tarpon Springs in the 7th percentile nationally for seismic hazard - higher than 7% of the 4,875 US cities USGS was checked against here.
