| Description | The Earth Observatory of Singapore–Myanmar (EOS–Myanmar) seismic array consisted of 30 broadband seismic stations that operated between May 2017 and December 2020. In this study, we use stations located on or near the rupture trace of the 2025 earthquake and apply the receiver function (RF) technique to investigate fault zone structures. For the RF analysis, we selected three‐component waveforms from earthquakes with magnitudes greater than 5.5 and epicentral distances between 30° and 90°. The seismograms were rotated into radial, transverse, and vertical components; windowed from −50 s to +100 s relative to the theoretical first P arrival; and bandpass‐filtered between 0.05 and 2.0 Hz. RFs were computed by deconvolving the vertical component from the radial/transverse components using a time‐domain iterative deconvolution technique with a Gaussian low‐pass filter (a = 3.0, approximately corresponding to a corner frequency of 1.5 Hz). Data quality control was applied to remove low‐quality RF traces. |

| Type | Raw teleseismic waveform data and processed receiver function (RF) waveforms. EOS-Myanmar.sta.txt – Station information, including network code, station name, latitude, and longitude. RAW – Raw teleseismic waveform data from the EOS–Myanmar seismic array, stored in SAC (Seismic Analysis Code) format. Deconv-3.0 – RF waveforms obtained via iterative time‐domain deconvolution with a Gaussian low‐pass filter (a = 3.0, ~1.5 Hz corner frequency), stored in SAC format. See the README file for further details. |
