Abstract The 2019 Ridgecrest, California, earthquake sequence included Mw 6.4 and 7.1 earthquakes that occurred on successive days beginning 4 July 2019. These two largest of the orthogonal faults ruptured Earth’s surface. To better evaluate 3D subsurface fault structure, (P- S-wave) velocity, temporal variations in seismicity, other important aspects sequence, we recorded aftershocks ambient noise using up to 461 three-component nodal seismographs for about months, one day after mainshock. ∼30,000Mw≥1 were dense arrays provide an unusually large volume data with which sequence. This report describes recording is intended metadata researchers interested evaluating various Ridgecrest set.
