Cosmic rays and earthquakes

Recommended Posts

In this study the authors found a significant correlation: global strong seismic activity followed about two weeks after detection of variations in cosmic rays. Causal connection is not clear, but the authors suggest either effects of massive movements of the liquid iron in the Earth core, or some effects of the Sun. They have noticed some additional correlations and periodicity, but these need more data.

I did geography. Earthquakes occur in the crust and upper mantle, only a maximum of 500miles deep. You then have to travel through the mesosphere, which is 1800 miles of rigid material. Before reaching the liquid core.

Would it effect the field. Maybe. It has to be a pretty big quake.

Theres you free geography lesson.

Their picture is that movements in the core cause changes in both the gravitational field and the geomagnetic field. The changes in geomagnetic field affect the cosmic rays behavior very fast. The changes in gravitational field affect the movements in the crust, but this takes time, thus the two weeks delay.
