Bulletin of the Seismological Society of America (1983) 73 (4): 979–1003.
...Brian W. Stump abstract A source characterization of bermed surface bursts utilizing vertical and horizontal point sources has been developed. The equivalence of this formulation with a radial force couple and vertical point force is shown. This representation is formulated so that with analytic...

The tsunami water together with underground water brought to the surface by soil liquefaction spread gasoline and other oils in the urban area, resulting in an extensive fire owing to oil ignition. The gasoline leaked from a 1,000-m 3 tank that was damaged by strong ground motions. The 1964 Niigata case...
