Shape Dynamic Time Warping for Seismic Waveform Inversion

We illustrate shape dynamic time warping (ShapeDTW) for 1D structure waveform inversion with examples from Tanzania, East Africa, and Northeastern Oklahoma. Seismograms of the Mw 5.9 Lake Rukwa, Tanzania earthquake (18 August, 1994) were recorded by 14 regional broadband seismographic stations. Seismograms of the Mw5.7 Prague, Oklahoma earthquake (6 November, 2011) were recorded by 8 regional broadband seismographic stations.

This dataset includes seismograms and solved velocity models.
In two examples, observed and synthetic seismograms are saved as SAC files in 'SAC_FILES' folders. The station numbers are listed in 'stationlist.txt' files. The 1D velocity models are saved as 'model.txt'.

我们以东非坦桑尼亚与美国俄克拉荷马州东北部的案例为例，展示了适用于一维结构波形反演的形状动态时间规整（ShapeDTW）方法。1994年8月18日坦桑尼亚鲁夸湖Mw5.9级地震的地震记录，由14个区域宽频带地震台站采集得到；2011年11月6日俄克拉荷马州布拉格Mw5.7级地震的地震记录，由8个区域宽频带地震台站记录。本数据集包含地震记录与反演得到的速度模型。在两个案例中，观测地震图与合成地震图均以SAC格式文件存储于'SAC_FILES'文件夹内；台站编号信息存储于'stationlist.txt'文件中；一维速度模型存储于'model.txt'文件内。
