Shallow Dynamic Overshoot and Energetic Deep Rupture in the 2011 Mw 9.0 Tohoku-Oki Earthquake
TL;DR: Finite-source imaging reveals that the rupture consisted of a small initial phase, deep rupture for up to 40 seconds, extensive shallow rupture at 60 to 70 seconds, and continuing deep rupture lasting more than 100 seconds, which may have enabled large shallow slip near the trench.

TL;DR: The NGA-West2 project is a large multidisciplinary, multi-year research program on the Next Generation Attenuation (NGA) models for shallow crustal earthquakes in active tectonic regions as discussed by the authors.
Journal ArticleDOI
Variability in earthquake stress drop and apparent stress
TL;DR: In this article, the authors apply empirical Green's function coda-based analysis to four earthquake sequences in Japan that span a magnitude range of 1.8 to 6.9, to measure radiated energy, corner frequency and stress drop.
Journal ArticleDOI
The limits of earthquake early warning: Timeliness of ground motion estimates
TL;DR: This work considers a zero-latency EEW system to determine possible warning times a user could receive in an ideal case, and finds that users who wish to be alerted at lower ground motion thresholds will receive more robust warnings with longer average warning times than users who receive warnings for higher groundMotion thresholds.
Journal ArticleDOI
Radiated seismic energy from coda measurements and no scaling in apparent stress with seismic moment
TL;DR: In this paper, an empirical Green's function (EGF) method was applied to the seismic coda in order to investigate scaling of the radiated seismic energy, which is consistent with independent measurements, where available.
