Disaster Alert is a free, mobile app that provides individuals, families, and their loved ones with the information they need to stay safe anywhere in the world. Built on PDC’s DisasterAWARE® platform, Disaster Alert™ offers near real-time updates about 18 different types of active hazards as they are unfolding around the globe.

With Disaster Alert, you can customize early warning alerts, view situational analysis reports, and access modeled hazard impacts for select hazards in a single, easy-to-use map interface. Disaster Alert’s continuous stream of new information is automatically derived from only scientifically verified sources. When no official source is available, alerts are updated manually, presenting a small lag in time.

Hazard updates provided with Disaster Alert include only active hazards. “Active Hazards” are part of a collection of recent incidents that have been designated as potentially hazardous to people, property, or assets by PDC.

Global events (Automated): Hurricanes (tropical cyclones / typhoons), earthquakes, tsunamis, volcanos, floods, wildfires. Also included for the U.S. only are tornados and winter storms.
Other Major events (Manual): Marine hazards, storms, droughts, and manmade incidents.Also included for Hawaii only are high surf advisories, high winds, and flash floods.

*Additional hazards will be included as new sources and algorithms are identified and verified.
*NEW: Free, customizable hazard alerts based on location and severity, with automatic updates as each new advisory is released
*NEW: Animated Layers (rainfall, clouds, winds, more…)
*NEW: Layers for tropical storm tracks and 20 other various incidents (including smaller earthquakes, etc.)
*NEW: Improved navigation and user experience, including user preferences for look and feel
*NEW: Support for select international languages (other languages are added over time)

This is a fantastic app I’d like to see being used worldwide! Using a system of communication with government disaster alerts and social media to communicate with the public in the line of fire, what others may not, we can all be quickly informed of local disasters to drive around, like CA fires, or when an earthquake across the world will or will not produce a tsunami threat! Great resource! Thank you to the dedicated staff working all ours to give us the latest weather & disaster related information like hurricanes, flooding, earthquakes, fires & more! Most current, local info at your fingertips!

So many problems

First off wouldn’t recognize my login information, had to create a new account. Not too much of a big deal but then I tried using the app..... horrible. The interface is real buggy, you have to tap on a location 30 times before it will actually register that you tapped it. Im sure the information from this app is great since it’s from the PDC, but it doesn’t help if you can’t even select the items you want the information from. Trying to change user preferences is basically impossible, I tried something as simple as changing the time zone. Wouldn’t recognize Tokyo as a time zone, then tried to select it by country but wouldn’t even let me select japan. Already given up, if the app can’t handle the basic things, then I don’t trust it to do anything else. From what I’ve been reading, it was great before a major update. My suggestion go back.

Eye Opening App

I don't know about other people but sometimes I get "tunnel vision" and tend to focus more on what is going on in my little corner of the world. This app has been an eye opener for me in terms of the bigger picture about calamities occurring all over our world. It is sobering to see so many disasters and makes me much more appreciative of each day. The app is easy to navigate and very informative. It's definitely a keeper.
