Tsunami source with revised CMT solution explains amplitudes at Hilo, HI

Model: MOST propagation model in spherical coordinate (Titov & Gonzalez,1997; Titov & Synolakis, 1998). Due to coarse grid resolution, only offshore wave propagation is modeled. Solid wall boundary conditions are set at 50m depth.
Bathymetry: Derived from Smith & Sandwell 2min data. Resolution of the computational grid is variable.It is ~6min near equator and becomes finer when moving south.
Source: CMT solutions from Harvard and USGS were used
  1. Harvard source model parameters
    1. NP1: 160km X 60km, slip=5m
  2. NEIC source model parameters
    1. NP1: 180km X 80km, slip=6.5m
    2. NP2: 180km X 80km, slip=6.5m
  3. Revised Harvard CMT New!
    1. NP1: 200km X 70 km, slip = 15m
