| Abstract: | This paper introduces the signal characteristics and the observed characteristics of continuous tremor waves in continent seismic observations. On the basis of identifying and extracting principles of tremor wave signals, improving the signal to noise ratio, reducing the analysis time scale, referencing international intermittent tremor positioning methods, improving the methods of signal identification, processing and positioning methods, we propose technological approaches and processes for positioning these kinds of signals. Further, we apply it to several tremor wave signals caused by typhoons in mainland Chinese seismic observation for positioning and effect testing. Results show that these technological approaches and processes are viable and that the positioning results are reasonable and believable. |
