... that caused severe damage in Sumbawa and Sumba Islands in Indonesia. The tsunami was also observed at tide gauges in Australia. We numerically computed a far-field tsunami, and we compared the observed tsunami waveforms on three tide gauges with the computed waveforms. We also numerically computed the tsunami...

...Donald L. Reed; Eli A. Silver; Hardi Prasetyo; Audrey W. Meyer Abstract The collision of the eastern Sunda arc with northwest Australia has resulted in the development of a suture between the Sumba ridge and Sawu-Timor terrenes along a zone of intraforearc convergence. The developing suture varies...
