Great California fault map without having to spend lots of time web-crawling and trying to navigate the convoluted USGS sites. Would like to have more backup data, though, such as type of fault, history of related earthquakes, and brief, non-scientific narrative of relative likelihood for future EQ's. if you can add hazard overlays (e.g. Liquefaction zones, tsunami threat, unstable soils, etc.), I know MANY of us living in the zones will be quick to subscribe and tell our friends and neighbors. This is a good start - keep up the good work!
Perfect tool for a realtor.
Pretty basic information every California resident should know. Wish it covered more than just California.
Very informative and easy to use!
In California everyone wants to know how far they and their relatives are from an earthquake fault. Will also be helpful when we feel the next quake.
With Family Sharing set up, up to six family members can use this app.
