主题：【原创】驳斥所谓的“地震反思”帖子...第一天 -- 南北朝大蟑螂

We have documented Quaternary activity on a set of large northeast-striking faults that parallel the eastern margin of the Tibetan Plateau, using a combination of field observations, photo and image interpretation, and Be exposure dating of offset depositional landforms. The northeast-trending Beichuan, Pengguan, and Dayi faults,

which parallel the eastern margin of the Tibetan Plateau, have been active in the latest Quaternary with a dominantly dextral sense of slip. Apparent throw rates are highly spatially variable but are typically <1 mm yr
1. Compelling and widespread geomorphic evidence for dominant dextral strike-slip displacement suggests to us that total displacement rates may be at least several millimeters per year. The Beichuan and Pengguan faults have experienced surface

rupture during the latest Pleistocene and at some locations during the Holocene. The faults are sufficiently long to sustain a strong ground-shaking earthquake, making them

potentially serious sources of regional seismic hazard.
