NH13E:
Advances in Tsunami Observation, Modeling, and Forecasting I


Session ID#: 10926

Session Description:
Recent improvements in tsunami observation platforms have led to the availability of an unprecedented amount of high-quality tsunami data. These include the deployment of ocean bottom pressure recorders throughout the Pacific basin, GPS buoys along tsunami-prone coastlines, seafloor GPS in subduction zones, and satellite measurements of open-ocean tsunamis. In this session we seek contributions from researchers that demonstrate how these data can be used to study the physics of tsunami generation, propagation and inundation, as well as how they can by utilized in next-generation tsunami warning and forecasting systems. Also welcome are presentations on new approaches to sea level measurements, as well as novel ways of using conventional measurements that yield new insight into tsunami physics, and new approaches to tsunami forecasting.
