Each QuakeFinder system consists of a 3-axes induction magnetometer, an air conductivity sensor, a geophone, and temperature/relative humidity sensors. There are no obvious charges in the positive/negative ions, the temperature, and the humidity, while the magnetometer, the geophone, and infrasound data detect clear co-seismic signatures, similar to seismic waves recorded by seismometers. The magnetometers register high-frequency pulsations, like seismic waves, and superimpose with low-frequency variations, which could be caused by the magnetometer shaking/tilting and/or the underground water level change, respectively, upon the arrival of seismic waves. The spectrum centering around 2.0 Hz of the co-seismic geophone fluctuations is similar to that of the seismic waves. However, the energy of co-seismic geophone fluctuations (also magnetometer pulsations) yields an exponential decay to the distance of a station to the epicenter, while the energy of the seismic waves is inversely proportional to the square of the distance. This suggests that the mechanisms for detecting seismic waves of the QuakeFinder system and seismometers are different. In general, the geophone and magnetometer/infrasound system are useful to record high- and low-frequency seismic waves, respectively."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004239384616072","@type":"Researcher","foaf:name":[{"@value":"Jann-Yenq Liu"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616071","@type":"Researcher","foaf:name":[{"@value":"Chieh-Hung Chen"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616069","@type":"Researcher","foaf:name":[{"@value":"Tsung-Yu Wu"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616068","@type":"Researcher","foaf:name":[{"@value":"Hsiao-Ching Chen"}]},{"@id":"https://cir.nii.ac.jp/crid/1420282801188048256","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60244513"},{"@type":"NRID","@value":"1000060244513"},{"@type":"NRID","@value":"9000002036916"},{"@type":"NRID","@value":"9000002249666"},{"@type":"NRID","@value":"9000410658026"},{"@type":"NRID","@value":"9000017743086"},{"@type":"NRID","@value":"9000415198426"},{"@type":"NRID","@value":"9000415150903"},{"@type":"NRID","@value":"9000001853812"},{"@type":"NRID","@value":"9000338691033"},{"@type":"NRID","@value":"9000338691034"},{"@type":"NRID","@value":"9000001570917"},{"@type":"NRID","@value":"9000005464254"},{"@type":"NRID","@value":"9000319050095"},{"@type":"NRID","@value":"9000001401220"},{"@type":"NRID","@value":"9000259324345"},{"@type":"NRID","@value":"9000283397887"},{"@type":"NRID","@value":"9000326645811"},{"@type":"NRID","@value":"9000001102459"},{"@type":"NRID","@value":"9000014540456"},{"@type":"NRID","@value":"9000297499699"},{"@type":"NRID","@value":"9000408791291"},{"@type":"NRID","@value":"9000001570865"},{"@type":"NRID","@value":"9000322102417"},{"@type":"NRID","@value":"9000259324290"},{"@type":"NRID","@value":"9000245917796"},{"@type":"NRID","@value":"9000271160317"},{"@type":"NRID","@value":"9000415220571"},{"@type":"NRID","@value":"9000259324271"},{"@type":"NRID","@value":"9000410350392"},{"@type":"NRID","@value":"9000259324296"},{"@type":"NRID","@value":"9000014663171"},{"@type":"NRID","@value":"9000408857904"},{"@type":"NRID","@value":"9000259324551"},{"@type":"NRID","@value":"9000415178470"},{"@type":"NRID","@value":"9000259324280"},{"@type":"NRID","@value":"9000338691027"},{"@type":"NRID","@value":"9000322102357"},{"@type":"NRID","@value":"9000415214414"},{"@type":"NRID","@value":"9000415175059"},{"@type":"NRID","@value":"9000415184979"},{"@type":"NRID","@value":"9000415193469"},{"@type":"NRID","@value":"9000345337981"},{"@type":"NRID","@value":"9000259324285"},{"@type":"NRID","@value":"9000259324303"},{"@type":"NRID","@value":"9000322102426"},{"@type":"NRID","@value":"9000002249720"},{"@type":"NRID","@value":"9000414562224"},{"@type":"NRID","@value":"9000415215394"},{"@type":"NRID","@value":"9000415170874"},{"@type":"NRID","@value":"9000398120757"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0071179"}],"foaf:name":[{"@value":"Katsumi Hattori"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616067","@type":"Researcher","foaf:name":[{"@value":"I-Ching Yang"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616073","@type":"Researcher","foaf:name":[{"@value":"Tom Bleier"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616064","@type":"Researcher","foaf:name":[{"@value":"Karl Kappler"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616065","@type":"Researcher","foaf:name":[{"@value":"Yaqin Xia"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616066","@type":"Researcher","foaf:name":[{"@value":"Weisheng Chen"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004239384616070","@type":"Researcher","foaf:name":[{"@value":"Zhengyan Liu"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"10170839"}],"prism:publicationName":[{"@value":"Terrestrial, Atmospheric and Oceanic Sciences"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2017","prism:volume":"28","prism:number":"5","prism:startingPage":"683","prism:endingPage":"692"},"reviewed":"false","url":[{"@id":"http://tao.cgu.org.tw/media/k2/attachments/v285p683.pdf"}],"createdAt":"2017-10-25","modifiedAt":"2021-12-31","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=QE1-996.5","dc:title":"QE1-996.5"},{"@id":"https://cir.nii.ac.jp/all?q=QC801-809","dc:title":"QC801-809"},{"@id":"https://cir.nii.ac.jp/all?q=Geophysics.%20Cosmic%20physics","dc:title":"Geophysics.
