How to Predict an Earthquake

Energy Transfer Energy Transfer Map

Take 2 quakes that struck on a plate fault line any distance apart and a quake can be predicted between these quakes on the fulcrum point. 

Fulcrum Point

When a quake strikes the Mid Atlantic Ridge say a M 5.0 within 24 hours a quake of the same magnitude will strike on the opposite side of the Earth. 
The Mid Atlantic Ridge is a wall for earthquakes to travel beyond. Energy cannot travel through this wall. 

Below is a picture of the North American Craton Plate.  A large earthquake that strikes the West Coast will sent energy East and follow the Craton in a counter clockwise direction around the Craton setting off more earthquakes.  Along the border of the Craton is where earthquakes occur

For earthquake reports go to USGS recent earthquakes for the last 24 hours

Given all the information above predicting the next earthquake is all about the energy transfer flow. Follow downstream along the fault line of the last quake is the focus. The United States, other then Alaska, California, and Oklahoma that get daily quakes, has fewer earthquakes then many other locations on the Earth. As an example, when an earthquake over M 4.0 strikes on the West Coast in the United States the pressure pushes East. The energy flow follows the fault line of the North American Craton that runs through Montana and in a counter clockwise direction through Yellowstone to Colorado to New Mexico to Texas to Oklahoma to Missouri to the New Madrid Seismic Zone to Tennessee and up the East Coast following the Appalachian Mountains. The Craton has many areas where oil fracking is going on like Colorado, Texas, and Oklahoma. One of these locations should get an earthquake that will make local news or national news. A sizable quake on the West Coast pushes pressure to the East. An earthquake striking on the Craton will transfer energy downstream.
