How rainfall variation can trigger earthquakes

Summary:
A new review article explores natural crustal earthquakes associated with the elements of the hydrologic cycle, which describes the continuous movement of water on, above and below the surface of the Earth, including hurricanes and typhoons. The theory of hydroseismicity, first articulated in 1987, attributes most intraplate and near-intraplate earthquakes, to the dynamics of the hydrological cycle.

The Hydroseismicity hypothesis suggests variations in rainfall affect pore-fluid pressure at depth and can trigger earthquakes in areas already under stress and near failure. This report cites documentation of metrological events -- rainfall, stream flow, hurricanes -- and observed seismic activity by more than 20 research teams across five continents, providing thorough testing and support of the Hydroseismicity hypothesis.

The authors suggest that the reported correlations between meteorological events and seismicity indicate the need for more local and regional earthquake monitoring networks as well as additional stream gauging stations. In the future it should be possible to discover and quantify causal relationships between earthquakes and meteorological parameters when better focal depths and more stream gauging stations become available. Groundwater hydrology measurements and earthquake monitoring and forecasting might eventually complement each other.
