Earthquake Alerts
for iPhone
Know about earthquakes the moment USGS detects them. Set your own rules — magnitude threshold, distance from home, time of day — and let Earthquake Globe handle the rest.

How earthquake alerts work
From seismic event to your iPhone in under 2 minutes.
USGS detects the earthquake
Seismograph networks around the world detect ground motion. USGS processes the data and publishes a preliminary magnitude within 3–5 minutes.
Earthquake Globe checks your rules
Our server fetches the USGS feed every 60 seconds and evaluates each new event against your notification settings: magnitude, location, and radius.
Alert sent via Apple Push Notification Service
If the earthquake matches your criteria, a push notification is sent through APNs — the same secure system used by all iPhone apps.
You receive the alert
Your iPhone displays the notification with magnitude, location, depth, and distance from your saved location. Tap to open the event on the 3D globe.
Full control over your alerts
Magnitude Threshold
Choose the minimum magnitude for alerts. Set M3.0 for local, M5.0 for regional, M6.0+ for only major events worldwide.
Location Zones
Add multiple locations — your home, a family member's city, a place you're traveling to. Each zone has its own settings.
Radius Control
Define how close an earthquake needs to be to trigger an alert. Options: 50, 100, 250, 500, or 1,000 km from your pin.
Do Not Disturb Hours
Set quiet hours so nighttime micro-tremors don't wake you up. Only significant events (e.g., M5.5+) break through.
Worldwide or Local
Switch between global alerts (any earthquake above your magnitude threshold) and location-specific radius alerts.
No Account Required
Notification settings are stored on your device. No registration, no email, no subscription. Just configure and go.
Your location stays on your device
Earthquake Globe does not collect or store your location. Alert zones are configured locally on your iPhone. The server only receives your notification preferences — never your GPS coordinates.
Frequently asked questions
How fast are earthquake push notifications?
Most notifications arrive within 60–120 seconds of USGS publishing the event. USGS typically publishes a preliminary magnitude within 3–5 minutes of the earthquake occurring, so total latency from quake to your iPhone is usually under 7 minutes.
Can I get alerts only for earthquakes near my location?
Yes. Set a radius alert centered on your current location or any saved location (home, family members' cities). Choose from 50 km to 1,000 km radius, so you only get notified about quakes that are actually relevant to you.
Will I get spammed with notifications for small earthquakes?
No. You control the minimum magnitude threshold. Most users set M4.0 or M5.0 for worldwide alerts and M2.5 or M3.0 for their local area. The app respects your settings exactly.
Do earthquake notifications work while the app is closed?
Yes. Earthquake Globe uses Apple Push Notification Service (APNs) to deliver alerts even when the app is not open. Your iPhone receives the notification from Apple's servers without the app needing to be running.
Is there a limit on how many notification zones I can set?
You can configure multiple notification zones for different locations — useful if you have family in a seismically active region or travel frequently. There is no hard limit on zones.
