Fault length (log L = 100 Km)
Fault width (log W = 50 Km)
Displacement (log D = 1 mt)
Strike angle (Parallel to Trench – Worst Case)
Dip angle (45 deg – Worst Case)
Slip angle (90 deg – Worst Case)
Models Cannot be run during the event due to large computing time and non-availability of Fault Parameters in real-time from Seismic Wave Form Data
Hence for Tsunami Forecasting, database of pre-run scenarios is essential
