Mae Chan Fault
Mae Chan Fault is an active 118 km long west-southwest–east-northeast trending left lateral strike-slip fault in Northern Thailand that extends into western Laos. It was responsible for a 6.3 magnitude quake in Laos on May 16, 2007, that caused property damage as far as Chiang Rai in Thailand. A part of it stretches from Mae Chan to Mae Ai for 40 km along the highway, then goes through Fang, Chiang Dao, Mae Rim and San Kamphaeng districts of Chiang Mai, to Mae Tha district of Lamphun. Tectonic setting It lies within the complex zone of collision between the Indian Plate and the Eurasian Plate. The orientation of this plate boundary is highly oblique to the direction of movement of the two plates. This has resulted in an area of dominantly strike-slip tectonics with the north–south trending right lateral Sagaing Fault and the northwest–southeast trending right lateral Red River Fault being the largest structures. The block between these two major fault zones is ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Fault
An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. * Active faulting is considered to be a geologic hazard - one related to earthquakes as a cause. Effects of movement on an active fault include strong ground motion, surface faulting, tectonic deformation, landslides and rockfalls, liquefaction, tsunamis, and seiches. Quaternary faults are those active faults that have been recognized at the surface and which have evidence of movement during the Quaternary Period. Related geological disciplines for ''active-fault'' studies include geomorphology, seismology, reflection seismology, plate tectonics, geodetics and remote sensing, risk analysis, and others. Location Active faults tend to occur in the vicinity of tectonic plate boundaries, and active fault research has foc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
