Check out Britannica's new site for parents! The occurrence of geomagnetic storms (Kp>4) appears to have a depressive effect on earthquakes during the peak of the storms.
This map shows Blot echoes (M4+ and >70km deep); the colored areas denote the location of deep earthquakes along subduction areas. The Earthquake Prediction Center at QuakeWatch.net is a division of SpaceWeatherNews and is supported by a collective of more than 400,000 people.

Earthquake forecasting: a review of radon as seismic precursor. The intention of EFS is to reduce damage and casualties caused by earthquakes.
Multiple events expand the ‘red-zone’ and colors fade over 72 hours. A strong anomaly gradient, within 10 degrees (map hash marks), over a fault line, is a strong atmospheric signal. The Earthquake Prediction Center at QuakeWatch.net is the home of the study of pre-seismic signals, and the practice of earthquake forecasting. Professor Emeritus of Earth and Planetary Science, University of California, Berkeley. ... First, techniques for the definition of the anomalies are described. Login This report, prepared for the National Earthquake Prediction Evaluation Council (NEPEC), is intended as a step toward improving communications about earthquake hazards between information providers and users who coordinate emergency-response activities in the Cascadia region of the Pacific Northwest. The model has been successfully predicting the location of M7+ earthquakes, within that 10 to 15%, approximately +80% of the time.The 48hr SDO/AIA 211 solar video shows coronal holes (CHs), the The Kp index (below) shows the level of geomagnetic activity resulting from space weather. Below, you can find the weekly and monthly anomalies, which tend to favor positive anomalies only.The Earthquake Prediction Center at QuakeWatch.net is the home of the study of pre-seismic signals, and the practice of earthquake forecasting. Of these, approximately 100 are of sufficient size to produce substantial damage if their centres are near areas of habitation. Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. The magnitude-7.0 earthquake struck the region the day before.Crowds watching the fires set off by the earthquake in San Francisco in 1906, photo by Arnold Genthe.
