Rapid coastal change is common in the Asia-Pacific region yet an understanding of its causes, recurrence times, and impacts is not always clear through the use of conventional geological methods. It is suggested that myths (traditional [oral] tales) are underutilized sources of information about coastal change in this region. This is illustrated by consideration of myths likely to recall (early...

Liquefaction has occurred during most earthquakes, Niigata 1964, Tangshan 1976, Loma Prieta 1985, Kobe 1995, Chi-Chi Taiwan 1999, Turkey 1999, Haiti 2010, Mexicali 2010 and others. The performance of structures during the Niigata earthquake (1964) in Japan and the nature of damage suffered by them clearly brought out the fact that soil and soil foundation interaction play a significant role in ...

A finite-element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic halfspaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic deformation predictions for the 1995 Colima-Jalisco M•o=8.0 earthquake. The FEMs are used to compute a coefficient matrix relating displacements at obs...

a doublet of earthquakes with magnitudes of 6.5 and 6.2 in mw scale (global cmt) on 2010 december 20 and 2011 january 27 respectively struck the area that lies between the nehbandan and jiroft fault systems, southeast of iran. these earthquakes occurred in correspondence of the southwestern termination of the kahourak right lateral strike slip fault. the focal mechanisms of both the mainshocks ...

[1] Earthquakes are accompanied with mass redistributions and cause changes in gravity field and shape of geoid, an equipotential surface coincident with the mean sea surface. Such coseismic changes were detected by satellite gravimetry after the 2004 Sumatra-Andaman Earthquake, but little has been known on what happens on geoid after the earthquake. Here we report slow postseismic recovery of ...

This archeoseismologic study focuses on the Leukos settlement that thrived west coast of forearc island Karpathos in 4th−6th centuries CE. The onshore site occupies eastern rim offshore Basin, deepest Aegean basin, a sector Hellenic typically regarded as seismically insignificant. Investigations faulting, sedimentary processes, and secondary earthquake effects (hydraulic fracturing, liquefactio...

We use horizontal and vertical crustal displacements derived from GPS measurements at 26 sites in western Mexico to study the coseismic and post-seismic kinematics and dynamics of the 1995 October 9 (Mw=8.0) Colima–Jalisco earthquake along the Middle America Trench. The measurements bracket the entire landward edge of the approximately 150 km long rupture zone and span a 4 yr period for most si...

Liquefaction of sand is not a rare geological phenomenon. When it happens, causes great damage to people. However, 1 District, Ho Chi Minh city where despite being leading economic and political zone city, many buildings with different loads metro lines have been will be rebuilt, but liquefaction potential has assessed. This paper presents study on belonging the Pleistocene lithological complex...
