March 2, 2011: Open-source risk vs. Proprietary risk models, a talk presented by Charles Scawthorn as part of a Distance Learning Seminar Series on Disaster Risk Management in East Asia and the Pacific, sponsored by the World Bank. Dr. Scawthorn spoke in favor of Open Source Risk Models to an audience at many places around the world, including Indonesia (Jakarta), Lao PDR (Vientiane), Thailand (Bangkok), Vietnam (Hanoi), Cambodia (Phnom Penh), China (Beijing), Mongolia (Ulaanbaatar), Philippines (Manila), Singapore (Singapore), Japan (Tokyo) and Fiji (Suva). View the 33 minute presentation here.
October 2010: ARkStorm, the Other Big One, a talk presented by Keith Porter to the Engineers' Forum, a seminar series sponsored by the East Bay Municipal Utilities District. Dr Porter gave an overview of an emergency planning scenario describing a hypothetical but realistic severe winter storm in California, and its impacts on the state's infrastructure, population, and economy.
