    Description
    Recent technological advances in computer and communication technology, as well as developments in seismic networks in the United States, have allowed seismologists to rapidly respond to earthquakes in revolutionary ways. Rather than limiting post-earthquake information to simply epicenter and magnitude, we can now rapidly provide maps of the intensity of shaking over the region affected by a damaging earthquake. One system, called “ShakeMap”, relies on shaking levels recorded at seismic stations to map out the distribution of shaking, pointing to the areas most shaking and likely to have experienced damage. These maps now provide the basis for emergency response coordination, estimation of damage and losses, and information for the public and the media. The second system, the Community Internet Intensity Maps (more commonly referred to as "Did You Feel it?") is a unique approach to Citizen Science. By collecting reports of what was felt and observed earthquake effects through the World Wide Web immediately after the shaking subsides, we can rapidly map out the extent and distribution of shaking and damage in any area of the country. Remarkably, the public has taken kindly to “Did You Feel it?”. In fact to date, we have logged over 350,000 individual entries to our questionnaire nationwide. This includes entries from all 50 states, plus the US Territories, indicating that the earthquake problem is indeed nationwide! In this lecture Dr. Wald will describe the science and technology behind these two new systems, including the complex nature of ground shaking and its effects on people and the built environment.
