Tidal waves are furiously fast; stay informed with these tools

If you need help with other types of natural disasters, there are lots of other emergency alert apps on the Play Store. Always listen to emergency officials in your area to be certain you have the very latest information for your location and situation.

Best Tsunami Text Alert System:

SMS Tsunami sample customization and alert screens
What We Like
  • Super simple concept.

  • Works with hundreds of carriers worldwide.

  • Monitors up to 5 locations.

What We Don't Like
  • Only email alerts are free.

  • No free trial period. provides a text messaging earthquake and tsunami warning platform interfaced with real-time data on global seismic activity sourced from official seismic research centers from around the world. This warning system differs from a standard application in that it's actually a GMS texting service that can work with more than 800 phone carriers.

Their system uses a sophisticated algorithm that estimates the level of risk associated with individual members based on several earthquake parameters such as quake location, magnitude, depth, type, and the location of the individual.

You can sign up for email alerts free with a combo of email, text, and voice alerts starting at $12.95 annually. Couple and family plans are available as well. The system allows you to customize your alerts, monitors up to 5 locations of your choice, and includes a test alert to ensure your phone works correctly with the service. The list of countries and carriers served is updated regularly; you're guaranteed text alerts when traveling to any of these locations and using these carriers.

Best Tsunami Evacuation App for Pacific Northwest Residents: NVS Tsunami Evacuation

NVS Tsunami Evacuation screens
What We Like
  • Clearly shows areas of risk.

  • Backed by NOAA.

What We Don't Like
  • Doesn't offer tsunami tracking information.

  • Only available for two states.

If you live in or travel to Oregon or Washington, you'll like this free app. It's a product of the Northwest Association of Networked Ocean Observing Systems (NANOOS) and sponsored by the National Oceanic and Atmospheric Administration (NOAA); you can use it to see if your current location is in a tsunami hazard zone.

It tells you if you are in a tsunami impact area that is likely to need immediate evacuation (10-20 minutes) after you feel an earthquake; if you have more time to prepare for evacuation (up to four hours); or if you're in a location that is considered safe from killer waves.

This app does not technically offer a tracking system, so it should be used in conjunction with one that actively tracks tsunamis in real time. However, it's an important app to have on hand if you are near the coastal regions of either state and feel the familiar shake of an earthquake.

What We Like
  • 18 types of hazard alerts.

  • Animated mapping.

What We Don't Like
  • Excessively slow load times.

This app is an all-around disaster app that offers information on disasters worldwide that have the highest potential to impact large populations. Built by the Pacific Disaster Center, Disaster Alert provides free alerts for 18 different types of hazards and covers the globe with its information.

Extras from this app include animated map layers, tropical storm tracking, and customizable hazard alerts based on location and severity. One word of caution: This app can have very slow loading times, bordering on unresponsive, due to the data it downloads from around the world. If you experience this issue, move on to another app; this one won't properly work on your device.

Best Real-time Tsunami Simulation: IH-Tsunami System

Screenshots from the IH Tsunami app.
What We Like
  • Simple, clear details.

  • Tsunami simulation and probability information.

  • Multiple filtering options.

What We Don't Like
  • Cannot customize to specific locations.

  • Not very intuitive to use.

  • Only available for Android devices.

When an earthquake occurs, this app notes earthquake location, size, and depth and calculates the probability of a resulting tsunami occurring. It also shows simulations of expected tsunamis, including sea surface height and travel time of the monster waves.

It does offer the ability to search earthquakes by magnitude or date, and you can check for those by day, week, or month, too. The geological information is provided via U.S. Geological Survey real-time information. Overall, this is a good app that can provide useful information if you are in an impacted area. However, it doesn't notify you of specific problems in your area; you'll need to monitor the app manually if you feel the earth move where you are.
