Abstract

With 299 fatalities, the 2024 New Year’s Day earthquake and subsequent tsunami that struck the Noto Peninsula was the deadliest since the 2011 Tohoku earthquake and tsunami. • Resolving the coseismic slip using a combination of tsunami, SAR-derived deformation and GNSS data can paint a more comprehensive picture of the rupture of the mainshock. • Obtaining a more complete catalog of seismicity to analyze its spatiotemporal evolution can better illuminate the physical drivers of this earthquake.

With 299 fatalities, the 2024 New Year’s Day earthquake and subsequent tsunami that struck the Noto Peninsula was the deadliest since the 2011 Tohoku earthquake and tsunami. • Resolving the coseismic slip using a combination of tsunami, SAR-derived deformation and GNSS data can paint a more comprehensive picture of the rupture of the mainshock. • Obtaining a more complete catalog of seismicity to analyze its spatiotemporal evolution can better illuminate the physical drivers of this earthquake.
The mainshock ruptured multiple fault segments along the Noto Peninsula, including a deeper offshore fault with a dip angle of 70°. • Adjoint inversion of tsunami data suggests a submarine landslide occurred in Toyama Bay. • Template matching and earthquake relocation reveal afterslip along both strike and dip. Fluid diffusion along dip seems to follow a healing front as opposed to the typical expansion associated with swarm activity.
