Earthquake Alerts
Stay informed about seismic activity around the world. WeatherAI monitors public earthquake feeds and can notify you when an event is reported near you or anywhere you care about.
Monitoring, not early warning.
These are informational notifications about earthquakes that have already been detected and reported. WeatherAI is not an earthquake early warning system such as ShakeAlert, and it does not issue tsunami warnings. It cannot alert you before shaking arrives. Notifications depend on feed publication time, network connectivity, your notification permissions and thresholds, and iOS delivery, so never rely on them as your only source. Follow your national seismological agency and local emergency management for official information.
Know When the Ground Shakes
Whether you live in earthquake-prone California, have family in Japan, or just want to stay informed about global seismic events, WeatherAI surfaces reported events as the feeds publish them.
Illustrative examples, not current seismic activity
Nearby Earthquake Detected
M4.2 earthquake 23 miles from your location in San Francisco, CA. Depth: 8.2 km. No tsunami warning.
Significant Global Event
M6.8 earthquake in southern Japan. Initial reports indicate moderate shaking in coastal areas.
Customizable Thresholds
Set your own magnitude thresholds: M2.0+ for nearby events, M5.0+ for significant global earthquakes.

Comprehensive Earthquake Monitoring
Multi-Source Data
Data from USGS (US Geological Survey) and EMSC (European Mediterranean Seismological Centre) for global coverage.
Nearby Detection
Automatic alerts for nearby earthquakes, with a minimum magnitude you choose so smaller events can be included or filtered out.
Customizable Thresholds
Set different magnitude thresholds for nearby earthquakes (default M2.0+) vs global significant events (default M5.0+).
Detailed Event Info
Magnitude, depth, distance, location, and time for each reported event. Early solutions are preliminary and agencies routinely revise them as more data arrives.
Depth View
Explore ten years of USGS earthquakes in cross-section. Compare their depths and magnitudes, and adjust the region and radius to investigate patterns below the surface.
Home Screen Widget
Add an earthquake widget to your iPhone home screen for at-a-glance seismic activity updates.
Who Benefits from Earthquake Alerts?
West Coast Residents
Challenge: Living along the San Andreas fault means earthquakes are a fact of life.
Set a low magnitude threshold for your own area and get notified as events are reported, from minor tremors to significant ones, with magnitude, depth, and distance.
International Families
Challenge: Loved ones in earthquake-prone regions like Japan, Chile, or Turkey.
Monitor significant global earthquakes (M5.0+) so you get a notification when something happens in regions you care about.
Emergency Preparedness
Challenge: Being ready for the next big one means staying informed.
Track seismic patterns over time. Understand local fault activity. Be informed, not surprised.
Travelers
Challenge: Visiting unfamiliar regions without knowing the seismic risks.
Automatic nearby detection works wherever you travel. Get alerts based on your current location, not just your home address.
Why People Turn These On
Local awareness
A low magnitude threshold surfaces the small nearby events that never make the news. A higher one keeps only what is worth reacting to. Both the threshold and the source, USGS or EMSC, are yours to choose.
Watching somewhere else
Global alerts cover events far from your saved locations, which is the usual reason people install an earthquake app at all: family in another country, a second home, a region they travel to. The earthquake widget keeps recent activity on the Home Screen.
Frequently Asked Questions
How quickly do earthquake alerts arrive?
Notifications go out once the USGS or EMSC feed publishes an event, which for larger earthquakes is usually within several minutes of detection. Actual arrival depends on feed publication time, network connectivity, your notification settings, and iOS delivery, so no specific timing is guaranteed.
What magnitude earthquakes are reported?
WeatherAI tracks earthquakes of all magnitudes from USGS and EMSC. You can customize alert thresholds to only receive notifications for earthquakes above your preferred magnitude.
Does the app show global earthquakes?
Yes, WeatherAI displays earthquakes worldwide using data from both the USGS and the European-Mediterranean Seismological Centre (EMSC).
