Asteroid Impact Tsunami: A Probabilistic Hazard Assessment
We investigate the generation, propagation, and probabilistic hazard of tsunami spawned by oceanic asteroid impacts. The process first links the depth and diameter of parabolic impact cavities to asteroid density, radius, and impact velocity by means of elementary energy arguments and crater scaling rules. Then, linear tsunami theory illustrates how these transient cavities evolve into vertical...
متن کاملMass transport events and their tsunami hazard
Mass transport events, such as those from submarine landslides, volcanic flank collapse at convergent margins and on oceanic islands, and subaerial failure are reviewed and found to be all potential tsunami sources. The intensity and frequency of the tsunamis resulting is dependent upon the source. Most historical records are of devastating tsunamis from volcanic collapse at convergent margins....

متن کاملThe earthquake and tsunami of 1865 November 17: evidence for far-field tsunami hazard from Tonga
S U M M A R Y Historical reports of an earthquake in Tonga in 1865 November identify it as the only event from that subduction zone which generated a far-field tsunami observable without instruments. Run-up heights reached 2 m in Rarotonga and 80 cm in the Marquesas Islands. Hydrodynamic simulations require a moment of 4 × 1028 dyn cm, a value significantly larger than previous estimates of the...
متن کاملContribution of Asteroid Generated Tsunami to the Impact Hazard
The long-standing uncertainty about the importance of asteroid-generated tsunami was addressed at a workshop in August 2016, co-sponsored by NASA and NOAA. Experts from NASA (Ames, JPL), NOAA, DoE (LLNL, SNL, LANL), DHS, FEMA, and academia addressed the hazard of tsunami created by asteroid impacts, focusing primarily on impacting NEAs with diameter <250m. Participants jointly identified key is...
