2011年9月3日至4日，台风塔拉斯经过日本西部的奈良县、和歌山县和三叶县时，该地区发生了大规模的深层山体滑坡。世界各地的地震台网记录了大型山体滑坡的信号，以前使用长周期波确定了大型山体滑坡的总力估计。本文研究了2011年塔拉斯台风引发的18个滑坡的高频波形和信号。滑坡的位置可以通过地震学反投影技术确定，这些位置与观测到的地表特征相关。我们发现滑坡的体积与从地震记录中提取的能量参数相关。
Large deep‐seated landslides occurred in Nara, Wakayama, and Mie prefectures of western Japan when Typhoon Talas passed through the region on September 3–4, 2011. Signals of large landslides have been recorded by seismic networks around the world, and overall force estimates have been previously determined for large landslides using long‐period waves. This study focuses on the high‐frequency waveforms and presents signals of 18 landslides caused by Typhoon Talas (2011). The location of the landslides can be determined by a seismological back‐projection technique and these locations correlate with the observed surface features. We have found that the volumes of the landslide correlated with an energy parameter derived from the seismic records.
