Not useful at all. – Quakes - Earthquake Notifications Review

Unresponsive app developer. Notification of an earthquake will give magnitude and area of location but, usually, you can’t find the location in the map. Even the list of earthquakes for a U.S. state or magnitude doesn’t list an large magnitude earthquake within 65 to 90 minutes of the notification—if at all. The pins indicating earthquake epicenters change location by as much as 600 miles when shrinking or expanding maps. What looks like an earthquake in your town is likely to have occurred elsewhere. Many epicenters are mis-plotted. The maps don’t show all the earthquakes that happen in an area until you get down to a scale so small you can’t see activity overall: thus, you can’t determine trends in the seismic activity. In essence, this app is of little scientific or professional value, and thus should be considered useful for entertainment purposes only if even that.
