Frequency-dependent seismic radiation process of the 2024 Noto Peninsula earthquake from teleseismic P-wave back-projection
Abstract
A large devastating earthquake of Mw 7.5 struck the Noto Peninsula, Japan, on January 1st, 2024. Persistent seismic swarms have preceded the main rupture around the hypocenter since 2020, likely driven by crustal fluids migrating upward from the lower crust. In this study, we investigated the frequency-dependent seismic radiation process using multi-frequency teleseismic P-wave back projection. The resulting source process reveals complex frequency-dependent behavior, which can be divided into four episodes. The initial episode lasts 15–20 s, characterized by high-frequency energy preceding low-frequency radiation. The second episode is marked ……
