| 英文摘要 |
A system, including seismic monitoring, crustal deformation, volcanic gas analyses, and geothermal measurement, has been established to monitor the volcanic activity of the Tatun Volcano Group. The real-time monitoring data will be useful in understanding the mechanism and behavior of volcanic eruptions, thereby alerting the public to possible volcanic activity and reducing the subsequent volcanic hazards. In general, seismic monitoring provides critical information for the evaluation of the possibility of volcanic eruption. Prior to volcanic eruptions, the hydrothermal system or magma becomes active, accompanied by many micro-earthquakes. Therefore, through the high-density seismic network, the temporal or spatial variations of seismicity in the Tatun volcano area will provide evidence of possible volcanism. |
