PORTLAND -- The American Red Cross has released an Earthquake App that offers tools to help prepare people for emergencies and alert them when a quake hits.

In addition to quake alerts and readiness plans, the app can also send a one-touch I m safe message to family and friends if your area has been affected.

Since the 1870s, Oregon has experienced two to three measurable earthquakes each decade, said Paula Fasano Negele of the Oregon Red Cross. In 1962, Portland was struck by a magnitude 5.5 quake and geophysicists say the area is vulnerable to even larger earthquakes.

The Earthquake App also offers epicenter, magnitude and intensity maps and directions to the nearest available Red Cross locations.

The earthquake app is free in the Apple and Google Play stores.
