<p>In this paper is observed a correlation between the Earth tide and earthquake occurrence that is closely related to the regional tectonic stress. It is investigated the direction of the tidal compressional stress using shallow earthquakes occurring in 100 ...

Tidal stresses beneath the oceans can be up to an order of magnitude higher than those found in the continents because of the eects of loading by ocean tides. I have analyzed 1899 microearthquakes recorded during a 55-day experiment on the Endeavour segment ...
