What this map shows
Explore worldwide USGS earthquakes reported in the past 24 hours, with felt reports and measured shaking where available. Circle size represents magnitude; reports and impact indicators are separate signals.
How to read this map
Magnitude measures earthquake size. USGS MMI is instrumental shaking intensity where available; DYFI felt count is the number of public responses reported with the event. The impact layer highlights observed evidence, not a MitchellCo damage prediction. Missing MMI or felt reports remain missing rather than being treated as zero. Ranking uses available evidence only and is a display heuristic, not an official risk score.
