Aftershock Forecast
- The data below are the most preferred data available
- The data below have NOT been reviewed by a scientist.
- Damaging earthquakes can occur in the future, so remember to: Drop, Cover, and Hold on.
- More earthquakes than usual (called aftershocks) will continue to occur near the mainshock. The mainshock is the largest earthquake in a sequence (a series of earthquakes related to each other).
- When there are more earthquakes, the chance of a large earthquake is greater which means that the chance of damage is greater.
- No one can predict the exact time or place of any earthquake, including aftershocks. Our aftershock forecasts give us an understanding of the chances of having more earthquakes within a given time period in the affected area.
Because this earthquake sequence is about 150 km (100 miles) from shore, only magnitude 5 events are likely to be felt by some people onshore and only a much larger, and unlikely, event would pose any hazard to buildings or people. This earthquake sequence affects both the U.S.A. and Canada. For information about this earthquake from our Canadian colleagues, please go to the Overview page in the left column and then look for the "For More Information" list and use the link to "Natural Resources Canada event page."
Aftershock Locations
This forecast applies to the area where the earthquake and aftershocks are already occurring, shown by the circle in the map below.
- hour
- day
- week
- month
- older than one month
- mainshock epicenter
Aftershock rates will decrease over time, but may remain elevated over the following year or longer.
This forecast will be updated as the sequence progresses and more information becomes available.
