Taitung earthquakes in Taiwan
نویسندگان
چکیده
Contrary to the normally observed increase in groundwater radon that occurs prior to earthquakes, we have measured anomalous decreases in radon concentration prior to the 2003 MW1⁄4 6.8 Chengkung and 2006 MW1⁄4 6.1 Taitung earthquakes that occurred within a 55 km radius from the Antung D1 monitoring well in eastern Taiwan. The v-shaped pattern of radon anomalies recognized at Antung is valuable for detecting the aseismic strain precursory to potentially disastrous earthquakes in a fractured aquifer surrounded by ductile aquitard in seismotectonic environments in this area. 2009 Elsevier Ltd.

متن کاملThe neotectonic architecture of Taiwan and its implications for future large earthquakes
The disastrous effects of the 1999 Chi-Chi earthquake in Taiwan demonstrated an urgent need for better knowledge of the island’s potential earthquake sources. Toward this end, we have prepared a neotectonic map of Taiwan. The map and related cross-sections are based upon structural and geomorphic expression of active faults and folds both in the field and on shaded-relief maps prepared from a 4...
