摘要

我们提出了CrazyBeachball，一个基于matlab的图形用户界面（GUI）软件包，设计用于使用纵波第一运动极性和S/P振幅比数据进行震源机制反演。CrazyBeachball将地震波形可视化、第一运动极性提取和震源机制反演集成到一个交互平台中。不像传统的方法，涉及单独的，独立的步骤，CrazyBeachball简化了过程，消除了外部数据转换的需要。其用户友好的界面允许有效的焦点机构确定，而其人机交互有助于提高质量控制。我们通过确定2021年杨壁MS6.4地震序列的21次余震的震源机制来证明其有效性，结果与区域应力场和断裂带几何形状一致。这个开源软件包还允许用户自定义，使适应特定的研究需求。

CrazyBeachball: A MATLAB GUI-based software package for focal mechanism inversion

We present CrazyBeachball, a MATLAB-based graphical user interface (GUI) software package designed for focal mechanism inversion using P-wave first-motion polarity and S/P amplitude ratio data. CrazyBeachball integrates seismic waveform visualization, first-motion polarity picking, and focal mechanism inversion into a single, interactive platform. Unlike conventional methods that involve separate, independent steps, CrazyBeachball streamlines the process and eliminates the need for external data conversion. Its user-friendly interface allows for efficient focal mechanism determination, while its human-machine interaction facilitates enhanced quality control. We demonstrate its effectiveness by determining focal mechanisms for 21 aftershocks from the 2021 M_S6.4 Yangbi earthquake sequence, with results aligning with the regional stress field and fault zone geometry. This open-source software package also allows for user customization, enabling adaptation for specific research needs.
