A Preliminary Study on Crustal Anisotropy in Chia-Nan Area of Taiwan

臺灣嘉南地區地殼剪波非均性初步研究

並列摘要


The instrumental observation of earthquakes in Taiwan has been initiatedsince 1898.Up to 1997,about 170,000 earthquakes have been accumulatedin the earthquake catalog.It is interesting to review this 100 yearseismicity at the end of this century.In this paper,we illustrate the distributionsof these earthquakes using different plotting techniques,under differentcategories to exhibit the nature of their occurrences.Some interestingearthquake distribution patterns are discovered,which may not be noticedbefore.It is no doubt that Taiwan earthquakes are stimulated by tectonicmovement around the island.By ultilizing earthquake distributionfigures,we attempt to relate the seismicity to the tectonics.Four seismicsystems which may be drived from different tectonic interactions are takento describe their particular seismicity patterns.Many interesting featuresof the tectonic movement can be explained by a careful examination of theseismicity distributions.Besides,we also hope that these well documentedearthquake figures will be useful for other purposes or simply for generalscience education.
