Περίληψη: 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 MS6.4 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. [ABSTRACT FROM AUTHOR]
