Potential for stronger seismic activity in or near the purple band 1-4 days. This is an estimate. Other regions are not excluded.

There is no scientific basis for earthquake predictions. There is always a chance for earthquakes in places with active faults, but specific forecasts perform no better than random when tested. Claims of correlation with planetary alignment have been disproven.
