What the numbers mean
- Tsunami flag
- The USGS sets this flag for large events in oceanic regions. It does not mean a tsunami happened or will happen. Official tsunami warnings come from the NOAA Tsunami Warning Centers at tsunami.gov.
- PAGER alert
- An automatic USGS estimate of likely fatalities and economic losses: green (little or none), yellow, orange, or red (highest). It can change as more data arrives.
- Felt reports
- People who felt shaking can describe it through the USGS "Did You Feel It?" survey on the event page. The count grows for hours or days after an event.
