This dataset contains distributed acoustic sensing (DAS) microseismic event triggers (waveforms) recorded during the 16A-16B circulation tests conducted at the Utah FORGE site in July 2023 as part of the FOGMORE R&D project (Utah FORGE Project 3-2417). Data were acquired using Silixa Carina and Silixa iDAS v2 systems on fiber optic cables installed in Well 16B(78)-32, with further details available in the Utah FORGE fiber-optic cable installation report linked below. The dataset consists of raw waveform data provided in nanostrain rate units, accompanied by channel coordinate information and a README.
