Within eleven minutes on 11 August 2012, twin earthquakes measured 6.3 and 6.4 on the Richter scale jolted Ahar and Varzaqan in northwestern Iran, claiming 300 lives and leaving thousands of injured in rural villages.12 The magnitude of the earthquakes was so immense that more than a hundred villages were 70-90% destroyed, while 20 being totally flattened. The primary estimations were suggestiv...

We study the one-loop radiative corrections to the SU(2) breaking mass splittings between sfermions in SU(2) doublets in the Minimal Supersymmetric Standard Model. At tree-level, the differences of mass squared m f̃1L −m f̃2L of SU(2) doublet sfermions (f̃1, f̃2)L in the first two generations are determined by tanβ, and are universal to sleptons and squarks. The radiative correction, however, break...

Compressional waves of an earthquake doublet (two events occurring in the South Sandwich Islands on 1 December 1993 and 6 September 2003), recorded at three seismic stations in Russia and Kyrgyzstan and reflected off Earth's inner core boundary, arrived at least from 39 to 70 milliseconds earlier in the 2003 event than in the 1993 event. Such changes indicate that Earth's inner core radius enla...

[1] We quantitatively map relative rate changes for the aftershock sequence following the second mainshock of the 1997 earthquake doublet (MW = 6.1, MW = 6.0) in the Kagoshima province (Japan). Using the spatial distribution of the modified Omori law parameters for aftershocks that occurred during the 47.8 days between the two mainshocks, we forecast the aftershock activity in the next 50 days ...

On December 7, 2012, a pair of large Mw 7.2 intraplate earthquakes occurred near the Japan Trench axis off Miyagi, northeast Japan. This doublet consisted of a deep reverse-faulting event followed by a shallow normal-faulting event. Aftershock observations using conventional and newly developed ultra-deep ocean bottom seismographs in the trench axis area showed that the shallow normal-faulting ...

Abstract Tsunami resonance excitation induces tsunami amplification, persistent oscillation, and strong current velocities, which may enlarge coastal hazards in tsunamigenic areas. Historically, the 2006 Pingtung earthquake doublet triggered tsunamis that affected south Taiwan coast. Studying features based on past is important for assessing obtaining critical disaster mitigation information. H...

Differential inner core rotation was first detected from time-dependent observations of differential travel times between PKP(DF) waves (which go through the inner core) and PKP(BC) waves (which turn at the bottom of the outer core) (Song and Richards, 1996). Criticisms concerning the reported detection have been raised, the most significant one being the possible bias from potential systematic...
