iSGTW Image of the week - Earth-quaking science in Hollywood

Image of the week - Earth-quaking science in Hollywood These images show results from simulations of a 4.2 local magnitude earthquake striking Hollywood, California, U.S. The left-hand column compares the effect of two different wave propagation codes when they both use the same velocity model. The top row shows results from one wave propagation code using two different velocity models. The bottom right image is a topographical map showing the epicenter of the event.

Now researchers with the Southern California Earthquake Center can find out.The SCEC have developed several seismological modeling codes that simulate earthquake processes, including earthquake wave propagation. These codes allow researchers to study the impact of the different earthquake source models, velocity models and modeling codes.Each simulation involves multiple computational stages, including preparation of input pa
