Stress-tensor components at SHZ following the 2025-07-30 Mw 8.8 Kamchatka earthquake (0–88 h)

Overview — This dataset contains time-series stress-tensor components recorded by the SHZ four-component borehole strainmeter following the Mw 8.8 Kamchatka Peninsula earthquake on 2025-07-30 (0–88 h, sampling rate 10 Hz). Columns: time, σxx, σyy, τxy, σm=0.5(σxx+σyy), τmax, etc. Units in Pascal. Times are in UTC+8 [state if converted from UTC]. Conventions — Tension is positive; compression negative; Channel-1 azimuth 25°; Young’s modulus = 7×10^10 Pa (70 GPa); Poisson’s ratio = 0.25; zero-stress reference time = 07:24 on 30 July 2025 (UTC+8).
