Rumor has it: The role of social ties and misinformation in evacuation to nearby shelters after disaster

Climate Risk Management, 2021
When crisis strikes, why do some communities utilize evacuation shelters more than others? This mixed methods study draws on a new dataset of almost-daily tallies of evacuees at 660 local shelters following Japan’s 2018 Eastern Iburi Earthquake in ...

Estimation of the source process and forward simulation of long-period ground motion of the 2018 Hokkaido Eastern Iburi, Japan, earthquake

Earth, Planets and Space, 2020
In this study, we investigate the source rupture process of the 2018 Hokkaido Eastern Iburi earthquake in Japan (M JMA 6.7) and how the ground motion can be reproduced using available source and velocity models.

GRAPES: Earthquake Early Warning by Passing Seismic Vectors Through the Grapevine

Geophysical Research Letters, Volume 51, Issue 9, 16 May 2024.
Abstract Estimating an earthquake's magnitude and location may not be necessary to predict shaking in real time; instead, wavefield‐based approaches predict shaking with few assumptions about the seismic source. Here, we introduce GRAph Prediction of Earthquake Shaking (GRAPES), a deep learning model trained to characterize and propagate earthquake ...
