Google confirmed Android Earthquake Alerts sent warnings to 11.4 million people before the recent Venezuela quake sequence, the first time the global system has issued advance notice at that scale outside of Japan or the US west coast. The Venezuelan event reset the conversation about earthquake apps on Android. The system-level alert from Google is now reliable in most countries with the right ground station data, but it is not a complete solution: it does not show post-quake intensity maps, it does not crowdsource felt reports, and it does not work for everyone in every region. We tested seven Android earthquake apps used in seismic regions to rank the ones that add genuine warning value beyond what Play Services ships by default.
The picks below cover live early-warning, post-quake feeds, citizen-science crowdsourcing, and the Google system alert that any Android user can enable in Settings without installing anything extra.
What to look for in an earthquake alert app
The category looks like seven copies of the same product until you sit with each one through a real quake. Five things matter:
- Warning time. The seconds between detection at the epicenter and shaking at your location matter more than any other feature. Apps that get this from a real seismic network beat apps that wait for a USGS feed.
- Region coverage. Most apps are strong in one or two countries and weak everywhere else. Match the app to where you actually live or travel.
- Alert reliability. False positives erode trust and quiet alerts cost lives. The best apps publish a public accuracy record.
- Post-quake reporting. The first thirty minutes after a quake is the period people are checking for damage, aftershocks, and felt reports. A clear map matters.
- Battery use. Apps that ride the phone's accelerometer drain more than apps that listen for a push notification.

The apps
1. MyShake: Best real early warning in supported regions
MyShake is the UC Berkeley Seismological Lab's app built on the same ShakeAlert backbone that powers the official US west coast warning system. In California, Oregon, and Washington it pushes alerts seconds to tens of seconds before shaking arrives, which is enough to drop and cover or stop a vehicle. The app uses your phone's accelerometer as part of a distributed sensor network when allowed, contributing to detection accuracy as more devices participate. The post-event Did You Feel It map and the educational drills are quietly the best in the category.
Where it falls short: Real early warning only works in regions where the underlying ShakeAlert sensor network operates. Outside the US west coast, the app becomes an information feed rather than a warning system.
Pricing:
- Free: full app, all features, no ads
- Paid: no
Platforms: Android, iOS
Bottom line: The default pick anywhere ShakeAlert operates. Outside that footprint, keep it as a secondary information feed.
2. Google Android Earthquake Alerts: Best system-level alert with zero install
Google Android Earthquake Alerts is the Play Services feature that delivered the Venezuela warnings. It is not a separate app: open Settings, search "earthquake," toggle Earthquake Alerts on. The system uses your phone's accelerometer to participate in a global crowdsourced network and shows a high-priority alert ahead of significant shaking when station data confirms the event. No account is required, no battery cost beyond what the system already pays.
Where it falls short: Limited to Android, no post-quake feed or aftershock follow-up, and the alert relies on having station coverage in your region. Coverage is patchy outside major seismic zones.
Pricing:
- Free: yes, bundled in Play Services
- Paid: no
Platforms: Android via Play Services
Download: Already installed on every Android phone with Play Services. Enable in Settings, search "earthquake."
Bottom line: Turn this on first, then layer a dedicated app on top for the post-quake context.
3. Earthquake Network: Best crowdsourced warnings worldwide
Earthquake Network is the longest-running crowdsourced quake warning app and the easiest way to get an early alert anywhere the Google network does not yet cover. Phones running the app form a distributed accelerometer mesh: when enough devices in one region detect shaking simultaneously, the server pushes an alert to nearby users. The map is busy but readable, and the user reports section gives you a quick sense of severity in the minutes after the event.
Where it falls short: Crowdsourcing means coverage scales with the user base. Quiet regions get fewer and less reliable warnings. Free tier ads are present.
Pricing:
- Free: full app, ad-supported
- Paid: small in-app purchase removes ads and unlocks higher-priority notifications
Platforms: Android, iOS
Bottom line: The right backup to Google's system alert in regions where Google's coverage is thin.
4. LastQuake: Best post-quake felt reports from EMSC
LastQuake is built by the European-Mediterranean Seismological Centre and is the post-quake app to keep on the home screen. The app shows confirmed events from EMSC inside the first minutes, with felt-report submission, photo upload, and a community map of where shaking was reported. The chat feature collects survivor accounts in real time, which is the closest thing on the storefront to a live ground-truth view of how big an event actually felt. The app is ad-free.
Where it falls short: Not an early-warning tool. The strength is what happens in the half-hour after a quake, not the seconds before.
Pricing:
- Free: full app, no ads
- Paid: no
Platforms: Android, iOS
Bottom line: Pair LastQuake with MyShake or Google's system alert. Early warning from one, ground truth from the other.
5. Volcanoes & Earthquakes: Best volcano context alongside seismic data
Volcanoes & Earthquakes by VolcanoDiscovery is the cross-reference app for anyone who lives near volcanic activity. The app aggregates feeds from EMSC, USGS, GFZ, and other agencies, but the killer feature is the volcano-watch overlay: every active volcano on the planet, current alert level, recent eruptions, and the seismic events around it. For travel to seismically active regions it is the most useful single map on the storefront.
Where it falls short: Information-first, not alert-first. The notification stream can be noisy if all the default filters stay on.
Pricing:
- Free: full feed with ads
- Paid: Pro tier removes ads and unlocks advanced filters
Platforms: Android, iOS
Bottom line: Worth installing for travel to Iceland, Indonesia, the Philippines, Italy, or anywhere on the Ring of Fire.
6. My Earthquake Alerts: Best customisable USGS feed
My Earthquake Alerts by J Ruston Apps is the most-installed third-party USGS-feed reader on the storefront and the easiest to filter down to exactly the events you care about. You set the minimum magnitude, the radius around your location, and additional saved locations for family or property, and the app pushes notifications inside seconds of USGS confirmation. The map is fast, the recent-events list is filterable, and the home-screen widget compresses the day's seismic activity onto a single tile.
Where it falls short: Feed-based, not early-warning. The notification arrives after USGS publishes, which means after the shaking. Ads on the free tier.
Pricing:
- Free: full feed with ads
- Paid: in-app purchase removes ads and adds extra widgets
Platforms: Android, iOS
Bottom line: The right "I want a USGS-feed reader on the home screen widget" pick.
7. Earthquake + Alerts, Map & Info: Best clean map and multi-source feed
Earthquake + Alerts, Map & Info by Briteapps is the multi-source feed app for buyers who want a single map combining USGS, GeoNet, EMSC, and Geoscience Australia data. The radius and minimum-magnitude filters are quick to set, the alert sound library lets you pick a distinctive tone, and the per-event detail page links out to the original agency report. Australians get the strongest experience because the app integrates Geoscience Australia natively.
Where it falls short: Feed-based, not early-warning. Some features sit behind a Pro unlock.
Pricing:
- Free: full feed with ads
- Paid: Pro unlock removes ads, raises filter limits
Platforms: Android, iOS
Bottom line: The right pick for buyers in Australia, New Zealand, or anywhere multi-source coverage matters more than a single agency feed.
How to choose
Start with Google Android Earthquake Alerts turned on in Settings. It is already on your phone, costs nothing, and is the only true early-warning system without an install step.
Add MyShake if you live or travel on the US west coast. Inside the ShakeAlert footprint it gives the same seconds-of-warning a dedicated network provides.
Add Earthquake Network as a crowdsourced backup in regions where Google's coverage is thin, especially Central and South America, Southeast Asia, and the Mediterranean.
Add LastQuake if EMSC's post-quake felt-report network matters to you, which it should if you care about ground-truth severity in the minutes after an event.
Pick Volcanoes & Earthquakes if your work or travel takes you near active volcanic regions.
Pick My Earthquake Alerts if a customisable USGS-only feed with a home-screen widget is the goal.
Pick Earthquake + Alerts, Map & Info if multi-agency feeds and Australian coverage matter most.
FAQ
How does Android Earthquake Alerts actually work?
Google's system uses the accelerometer in opted-in Android phones to detect shaking. When enough phones in one area report tremors at the same time, the server confirms an earthquake and pushes a high-priority alert to phones farther from the epicenter. The lag between detection and notification can be enough for several seconds of warning depending on distance.
What is the best free earthquake alert app for Android?
Google Android Earthquake Alerts via Play Services is free, built in, and the only true early-warning system available everywhere. For a feature-rich free third-party option, MyShake is the strongest pick inside the ShakeAlert footprint and LastQuake is the strongest pick outside it.
Do earthquake apps drain battery?
Feed-based apps like My Earthquake Alerts use almost no battery; they wake briefly when a push notification arrives. Crowdsourced apps like Earthquake Network and MyShake use slightly more because they sample the accelerometer in the background. Google's system alert uses the bare minimum because it shares Play Services overhead.
Can I get an earthquake alert before the shaking arrives?
Yes, sometimes. Early warning systems work because shaking travels through the ground at a few kilometres per second, slower than a notification can reach your phone. The seconds of warning depend on distance from the epicenter and on station coverage in your region.
Which earthquake app works best outside the US?
LastQuake from EMSC is the strongest pick for Europe, North Africa, and the Mediterranean. Earthquake Network has the broadest crowdsourced coverage worldwide, especially in Central and South America. Google's system alert now works in many countries Google has signed agreements with for ground station data.
