On April 1st, 2014, an earthquake with moment magnitude Mw 8.2 occurred off the coast of northern Chile, generating a tsunami that prompted evacuation along the Chilean coast.
Here, tsunami characteristics are analyzed through a combination of fi...


A study on vehicle traffic demand during a post-disaster recovery period for planning Emergency Relief Logistics
Kentaro Kumagai and Kenji Ono
Proceedings of Infrastructure Planning   60    2019
Emergency Relief Logistics, ERL, is performed during a post-disaster recovery period after a large-scale earthquake. In order to deliver relief supplies to evacuation sites appropriately, it is required to per-form traffic simulation in advance an...
