Tectonic blocks and suture zones of eastern Thailand: evidence from enhanced airborne geophysical analysis

Annals of Geophysics, 2013
Airborne geophysical data were used to analyze the complex structures of eastern Thailand. For visual interpretation, the magnetic data were enhanced by the analytical signal, and we used reduction to the pole (RTP) and vertical derivative (VD) grid ...

Longer aftershocks duration in extensional tectonic settings [PDF]

Scientific Reports, 2017
AbstractAftershocks number decay through time, depending on several parameters peculiar to each seismogenic regions, including mainshock magnitude, crustal rheology, and stress changes along the fault. However, the exact role of these parameters in controlling the duration of the aftershock sequence is still unknown.
