Radon monitoring in Tatun volcanic areas and some mud volcanoes of Southern Taiwan for seismic and volcanic study using active and passive techniques

Integrated radon monitoring using solid state nuclear track detectors (SSNTDs) technique has been carried out at Tatun volcanic areas of northern Taiwan. The pre-calibrated radon thoron discriminators with LR films has been installed in Hsiaoyoukeng (SYK), Dayoukeng (DYK), Bayen (BY) and Gungtzeping (GTP) of Tatun Volcanic area in a hole (about 50 cm depths) having different temperatures for a defined period (bi-weekly to monthly). The preliminary results have shown that our monitoring stations in TVG area are sensitive to the events with in distance 60 kms. We have kept integrated monitoring at TVG area to test and verify the hypothesis mentioned above. Furthermore, we are also working on some selected mud volcanoes of southern Taiwan i.e. Mai-Tao-San and Wan-dan. We are carrying out integrated radon monitoring with passive (SSNTDs) and active (RAD7) detector in soil and radon monitoring in water with active (RAD7) detector. The results of this integrated radon monitoring in water and soil at Mai-Tao-San areas and Wan-dan areas of Taiwan for seismic and volcanic study will also be discuss in detail
