A good correlation is obtained between earthquake occurrence in the northern Jordan Rift Valley of Israel, the lowest seasonal Lake Kinnereth levels and the start of the rainy season. It is suggested that the start of the rainy season and the following recharge of aquifers increase the confined hydrodynamic pressures and flows along the boundary faults which also act as groundwater conduits. This in turn increases lubrication and decreases the friction along the faults; as a result, earthquakes which would have occurred at some later time, are triggered.
