Conclusions

We are currently generating an animated AlertMap for the first 60 seconds of each event of $M \geq 3$ in northern California. These AlertMaps allow us to assess simply and quickly the performance of ElarmS for each of these events. The information presented in these maps is organized in an intuitive geospatial manner which is immediately familiar to users of ShakeMap, allowing for easy direct comparison between ElarmS predicted ground motions and actual observed ground motions represented in the regular ShakeMap product.
