Simple and Informative

This app is very simple to use, and its very easy to interpret the results for earthquake probabilities and risk

Great app

The only mobile app available to my knowledge that actually lets you know your risk with excellent science.

First of its kind with sound science basis

This app is based on the OpenHazards earthquake forecasting methodology, based on years of development and testing. The interface is clean and easy to use.

Add this feature

This is a nice app but what it really needs is the ability to utilize the iPhone accelerometer to detect earthquakes and automatically share that data to the cloud and/or the USGS. Only when enough similar readings are detected from a certain region within a narrow timeframe would the data be considered legitimate and then be pushed back out to the map for all users to view. The app could also be active only at certain times of the day/night that the user defines. As well as only be active when connected to pre-defined wifi networks. Such as Home or work. Another option would be to only take accelerometer reading when it is plugged into power (such as when on your night stand or connected to a computer USB). The app could also use the iPhone GPS to disable sensor reading when moving. As well as only record seismic data when the app detects the iPhone is laying flat on its back. Another option would be to disable the seismic sensor data output when a face is detected with the front facing camera. Requiring the app to be running in the foreground would also further prevent false readings. This could easily, quickly, and cheaply create a huge network of seismographs around the world.
