摘要 设计并实现了同震地表破裂空间分布形态的无损测量方法和基于Python平台的自动测量工具,可获得与原数据同等精细程度的地表破裂带空间分布形态及宽度的测量值。以2021年青海玛多MW7.4地震和1983年Idaho Lost River MW6.9地震数据进行性能测试,结果表明,该方法可自动、精细、灵活地测量并绘制地表破裂的空间分布形态。
Abstract:We design and implement a nondestructive measurement method for the spatial distribution of coseismic surface rupture and an automatic measurement tool based on the Python platform; the method can obtain the spatial distribution and width of surface fractures with the same degree of precision as the original data. We take the Maduo MW7.4 earthquake in 2021 and the Idaho Lost River MW6.9 earthquake in 1983 as examples. The results show that this method can measure and map the spatial distribution of surface rupture automatically and flexibly.
