“…Muço (1995) noted the tendency of Albanian earthquakes to occur in the wet part of the year, with a strong correlation between precipitation and earthquakes. He found a better correlation between rainfall and earthquakes for the inner zones of the country than for the coastal regions.…”

Most natural crustal earthquakes fall into one of two categories:(1) those associated with the dynamics of plate tectonics, or (2) those associated with the elements of the hydrologic cycle. This paper presents a comprehensive listing of published examples of hydroseismicity, a hypothesis that attributes most intraplate and near-intraplate earthquakes to the dynamics of the hydrologic cycle, which includes hurricanes and typhoons. Results from 30 worldwide studies of earthquake-rainfall correlations published during the past 22 years are referenced. These investigations were conducted in both intraplate and plate marginal environments on five continents. Collectively, they provide strong support for the hydroseismicity hypothesis as a viable explanation via pore-fluid-pressure diffusion for the occurrence of many earthquakes, regardless of the host tectonic regime. Signatures of pore-fluid-pressure diffusion in the Earth's crust are ubiquitous. Slow earthquakes result from crack development driven by pore-fluid-pressure diffusion. These earthquakes, also called silent earthquakes, take days, weeks, or even months to release energy instead of seconds or minutes as in normal earthquakes. Typhoons can trigger slow earthquakes in some areas. Hurricanes are believed to have triggered earthquakes in the eastern United States. Their explanation is provided for the most part by Biot's theory for wave propagation and pore-fluid-pressure diffusion in poroelastic media.

“…A less-known source of hydroseismicity is rainfall, which leads to pore-pressure changes in the crust due to the infiltration of water in the ground. While previous evidence came mainly from positive statistical correlations between rainfall and seismicity (Muco 1995;Svejdar et al 2011), Hainzl et al (2006Hainzl et al ( , 2013b performed a quantitative physical analysis of this triggering process for the case study of the seismicity occurring below Mt Hochstaufen, SW Germany. Based on Coulomb stress calculations and the assumption of rate-and state-dependent frictional nucleation they could show that rainfall seems to be the dominant triggering process in this specific location.…”

“…Earthquake seasonality (i.e., a bias favoring seismicity in one season) was documented three decades ago along the PNA plate boundary (McClellan, 1984) and has since been reported in almost every other type of plate tectonic setting, including convergence zones in the western Pacific (Matsumura, 1986;Ohtake and Nakahara, 1999;Heki, 2003), the Himalaya (Tiwari et al, 2005;Bettinelli et al, 2008), and the Mediterranean region (Pedrami, 1985;Muço, 1995;Hainzl et al, 2006); transforms in New Zealand and offshore of Oregon (Matsumura, 1986); the Gorda ridge (Matsumura, 1986) and mid-Atlantic spreading zones (Jónsdóttir et al, 2007); and oceanic and continental intraplate areas (Jiménez and García-Fernández, 2000;Costain, 2008).…”

“…Explanations for the seasonality are typically ad hoc and local, invoking seasonal fluctuations in ambient atmospheric pressure (Ohtake and Nakahara, 1999;Gao et al, 2000) or temperature (Ebel and Ben-Zion, 2007), ocean-bottom hydrostatic pressure (Heki and Kataoka, 2006), glacial melt (Jóns-dóttir et al, 2007), montane snow loading (Heki, 2003), rainfall (Matsumura, 1986;Muço, 1995;Jiménez and García-Fernández, 2000;Hainzl et al, 2006;Costain, 2008), river discharge (Bettinelli et al, 2008), surface reservoir (Tiwari et al, 2005) or groundwater storage (Hainzl et al, 2006;Bettinelli et al, 2008), and sedimentation rate (Westaway, 2002).…”

Large mainshocks in the Uniform California Earthquake Rupture Forecast (UCERF) catalog appear to have been nonrandom in time in the northern California region. Magnitude M ≥ 6:4 earthquakes clustered significantly in the halfyearly solar declination cycle. The most likely explanation appears to be natural earthquake periodicity, because the semiannual bias (1) persists in historical and instrumental catalog subsets, regardless of foreshocks or aftershocks, (2) is not contradicted by pre-1850 data for northern California, and (3) is replicated in southern California subregions, other plate-tectonic settings, and global seismicity. Alternatively, the UCERF catalog has overlooked many M ≥ 6:4 mainshocks that occurred outside of the observed semiannual clustering phase or contains systematic errors that bias the distribution of large earthquakes in the semiannual cycle. The semiannual clustering in northern California shifted abruptly after the great 1906 earthquake from a phase during the month after equinox to a phase near solstice, with large earthquakes returning to the postequinox phase since about 1980. In some other regions where semiannual clustering is evident, a similar phase shift occurred after a great earthquake. Correspondence between the semiannual phase and the tectonic regime of the clustered earthquakes suggests those two parameters may be related. I speculate that the apparent periodicity is a response of the regional fault network to the semiannual solid-earth tide and explore possible explanations for the shift in its net phase after a great earthquake.
