On-Site Estimation of Peak Ground Acceleration Using the S/P Amplitude Ratio for MEMS-Based Earthquake Early Warning Systems in Iași, Romania

This study presents a site-specific calibration of the ratio between S-wave and P-wave peak ground acceleration (PGA) for use in low-cost, on-site earthquake early warning (EEWS) systems in Iași, Romania. A dataset of 25 intermediate-depth Vrancea earthquakes (Mw 4.1–5.7; epicentral distances 150–21...
