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.
- Local time
- The local time at the epicenter is not shown because the area spans more than one time zone or is offshore.

After an earthquake
Expect aftershocks. If you are near the coast and feel strong or long shaking, move to high ground right away without waiting for an official warning. Check on neighbors and follow instructions from local emergency officials.
