Earthquake Alert Not on My Phone — How to Enable Real-Time Seismic Notifications on iPhone, Android, and Every Major App

Cracked ground after an earthquake — how to enable earthquake alerts on iPhone and Android

An earthquake happened and your phone never alerted you — or you heard about it on the news before your device made a sound. Earthquake early warning systems exist on both iPhone and Android, but they're disabled by default on many devices and require specific settings to activate. Here's exactly how to turn them on for every platform.

iPhone (iOS 15 and later)

Step 1: Enable Emergency Earthquake Alerts

iPhone receives earthquake alerts through the Wireless Emergency Alert (WEA) system — the same system used for Amber Alerts and flash flood warnings. It's turned off by default on some devices after an iOS restore.

  1. Go to Settings → Notifications → scroll all the way to the bottom.
  2. Under Government Alerts, confirm Emergency Alerts is toggled ON.
  3. Also enable Public Safety Alerts — earthquake warnings are sometimes distributed through this channel depending on your region.
  4. Confirm "Always Deliver" appears — this means alerts override Silent mode and Do Not Disturb.

Step 2: ShakeAlert Integration (US West Coast Only)

If you're in California, Oregon, or Washington, iPhone integrates with the USGS ShakeAlert early warning system — but only on iPhone 14 Pro and later models running iOS 17+.

  1. Go to Settings → Emergency SOS.
  2. Look for Earthquake Warnings — toggle it on if available for your region.
  3. If the option doesn't appear: your device or iOS version doesn't support ShakeAlert integration. Use a third-party app (see below).

Step 3: Add a Dedicated Earthquake App

For notifications beyond the WEA system, install one of these:

  • MyShake (UC Berkeley): Free, iPhone and Android. Provides early warning alerts for the US West Coast and global earthquake reports. Search "MyShake" in the App Store.
  • QuakeAlertUSA: Free, US-focused, integrates with ShakeAlert. Covers CA, OR, WA.
  • USGS Earthquake Hazards: Not a real-time alert app, but provides the most accurate post-event data at earthquake.usgs.gov.

Android

Android phone with emergency alert notification — how to enable earthquake warning on Android Google

Step 1: Enable Android Earthquake Alerts (Built-In)

Android has built-in earthquake detection and alerting powered by Google's seismometer network — using your phone's accelerometer to detect shaking. This is separate from the WEA system and can provide earlier warnings.

  1. Go to Settings → Safety & Emergency (stock Android/Pixel) or Settings → Advanced Features → Emergency SOS (Samsung).
  2. Tap Earthquake alerts — toggle it ON.
  3. If you don't see "Earthquake alerts" in Safety & Emergency: go to Settings → search "earthquake" in the settings search bar — it may be nested differently depending on your Android version.

Step 2: Enable Wireless Emergency Alerts (WEA)

  1. Open the Phone app → three-dot menu → Settings → Emergency alerts.
  2. Or: Settings → Notifications → Advanced → Emergency broadcasts.
  3. Enable Extreme threats and Severe threats — these categories cover earthquake warnings distributed through the government WEA system.
  4. Also enable Alert sound and Alert vibration — without these, alerts arrive silently.

Step 3: Samsung-Specific Path

  1. Go to Settings → Safety & Emergency → Wireless Emergency Alerts.
  2. Enable all threat categories.
  3. Also check: Settings → Advanced Features → Send SOS messages — Samsung's emergency settings are sometimes split across multiple menus.

Third-Party Earthquake Apps: Which One to Use

The best app depends on your location:

  • MyShake (US, global): Best overall. Combines ShakeAlert early warning (US West Coast) with global earthquake reports. Sends alerts before shaking arrives — the earlier the warning, the more useful it is. Available iPhone and Android.
  • Earthquake Network: Crowdsourced early warning using phone accelerometers. Works globally including in countries without government early warning systems. Useful for international travel.
  • LastQuake (EMSC): European-Mediterranean Seismological Centre app. Best for Europe, Middle East, and North Africa coverage. Also covers global major events.
  • Colombia/Latin America specifically: The SGC (Servicio Geológico Colombiano) provides official earthquake information at sgc.gov.co — sign up for their alert list directly for Colombian seismic activity.

Why You Might Not Have Received an Alert Even With Everything Enabled

  • Earthquake was too far away: WEA earthquake alerts are geo-targeted — if the epicenter was in a different region, your phone may not have been in the alert zone even if you felt the shaking.
  • Earthquake was below alert threshold: Most systems only send alerts for earthquakes M4.5 or larger — smaller earthquakes are reported but don't trigger push alerts.
  • No early warning system exists in that region: ShakeAlert only covers the US West Coast. Most of the world doesn't have a functional early warning system yet — real-time reports from USGS or EMSC are the closest alternative.
  • Alert arrived after shaking started: This is normal for earthquakes close to your location — the P-wave (first wave) travels faster than the warning system can process and transmit. Early warning systems provide seconds to tens of seconds of advance notice, not minutes.

Bottom Line

Earthquake alerts on iPhone come through the WEA system (Settings → Notifications → Emergency Alerts → ON) and, on newer US West Coast iPhones, through ShakeAlert (Settings → Emergency SOS → Earthquake Warnings). On Android, the built-in Google earthquake alert system (Settings → Safety & Emergency → Earthquake alerts) provides the fastest notification — enable it alongside WEA Emergency Alerts for maximum coverage. For global coverage or regions without government early warning systems, the MyShake app (free, iPhone and Android) is the most reliable supplemental tool. If you didn't receive an alert for a specific earthquake, check the USGS event page at earthquake.usgs.gov — it will show the magnitude, location, and which alert zones were triggered.

Which region are you in, and which device are you using? Drop it in the comments and we'll confirm which alert system covers your area.

YouTube Keeps Logging Me Out on Samsung Smart TV After the 2026 Update

If you've recently updated your Samsung Smart TV and now find yourself getting signed out of YouTube every few minutes, you're not alone. This issue spiked noticeably after the latest firmware rollout, and it's frustrating enough to make you want to throw the remote across the room. Here's what's actually going on, and how to fix it without resetting your entire TV.   Why This Is Happening The short version: the 2026 Tizen firmware update changed how Samsung TVs handle cached authentication tokens for third-party apps. YouTube relies on a locally stored session token to keep you logged in, and the update appears to be clearing or corrupting that token faster than it should — sometimes within minutes of signing in. This isn't a YouTube-side bug. It's a conflict between Samsung's updated app sandboxing and YouTube's token refresh cycle.   Common Fixes (Try These First) Restart the TV — Hold the power button for 5 seconds, not just a quick press.

Amazon Order Stuck on "Preparing for Shipment" for Over a Week? Here's What's Really Happening

Your order says "Preparing for Shipment" and it hasn't moved in days. You've refreshed the tracking page a dozen times, maybe even called support and gotten a generic script read back to you. So what's actually going on, and is there anything you can do besides wait? Let's break it down. What "Preparing for Shipment" Actually Means This status doesn't mean your package is sitting untouched. It means Amazon's fulfillment center has confirmed your order but hasn't yet handed it off to a carrier for scanning. The label may already be printed. The item may already be boxed. It's the handoff step — between warehouse and shipping carrier — that's stalling. There are three common reasons this drags on past 2-3 days: Inventory mismatch — the system shows stock available, but the physical item isn't where it's expected to be in the warehouse, triggering a manual recount Carrier capacity issues — especially common arou...

Paid for YouTube Premium but Still Seeing Ads? Here's the Real Fix

You upgraded to YouTube Premium specifically to get rid of ads, and now they're still showing up. Before you contact support and sit through a generic troubleshooting script, here's what's actually causing this — and the fix that works when the obvious steps don't. The Three Most Common Reasons Premium Isn't Blocking Ads Not all ad situations are the same. Which one you're dealing with changes what you need to do. 1. Your account isn't signed in on the device showing ads This is the most common cause and the easiest to miss. YouTube Premium is tied to your Google account, not to the app or device. If you're watching while signed out — or signed into a different Google account — YouTube has no way of knowing you're a Premium subscriber. Check the account icon in the top-right corner of the YouTube app and confirm it shows your correct profile. 2. Your Premium subscription lapsed without warning YouTube sometimes fails to send a renewal failu...
