Simulating 800,000 Years of California Earthquake History To Pinpoint Risks
aarondubrow shares a report from the Texas Advanced Computing Center: A new study in the Bulletin of the Seismological Society of America presents results from a new earthquake simulator, RSQSim, that simulates hundreds of thousands of years of seism.....»»
Simulating 800,000 years of California earthquake history to pinpoint risks
Massive earthquakes are, fortunately, rare events. But that scarcity of information blinds us in some ways to their risks, especially when it comes to determining the risk for a specific location or structure......»»
Simulating evolution to understand a hidden switch
Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changing some of their characteristics. Maintaining this "hidden" switch is on.....»»
