How This San Mateo Tracker Works
The live explorer starts with M2.0+ events within 100 km during the past 30 days. Changing a filter requests a new result set from the USGS Event Web Service; it does not estimate or invent seismic activity.
An epicenter may be outside the city boundary. Magnitude measures energy released at the source, while felt shaking also depends on distance, depth, local geology and construction. “No matching events” means none met the displayed catalog filters.
