The Earthquake Notification Service (ENS) sends free automated notification emails when earthquakes happen in your area or anywhere in the world.

You customize ENS to report based on where and how large the earthquake is. That might be:

Large earthquakes anywhere in the world,
Moderate earthquakes in the U.S., or
Earthquakes of any size near you.

Users can have multiple email addresses. ENS can also text your cell phone if your carrier supports email-to-text functionality.

All ENS notifications give a short text summary plus a link to the full product. List of available products.

News and Notifications

Your Earthquake Notification Service account can now deliver new message types - PAGER, ShakeMap, ShakeAlert®, and OAF. For more information or to sign up, log in to your account and choose messages of interest.
ENS can send any or all of four new message types:
- PAGER - Summary of estimated earthquake impact on people and property.
- Operational Aftershock Forecast (OAF) - Description of aftershock expectations following earthquakes in the U.S. and Territories.
- ShakeMap - Notifies when a ShakeMap has been made for an earthquake.
- ShakeAlert® - Reports that a new ShakeAlert® Earthquake Early Warning System report is available.
Each message is sent separately, so one earthquake can generate up to five notifications. Current users will continue to receive Event messages that fit their current magnitude and region settings.

Inactive users: Some ENS account holders have no method on file to send notifications. We have no way to contact you! To keep your ENS account, please log in and add your email or SMS information. Accounts with no contact information will be removed.
