About these reports & download the data
These are public USGS geographic aggregates, not individual questionnaires. Community intensity describes the combined responses for an area; it does not measure shaking at every building. Small groups and USGS-flagged areas deserve extra care. ShakeMap estimates and community reports are separate products.
