Ge 263 HWK 3: Finite-Difference Tsunami Example with a Rupture Source

February 3, 2005

Given problem
Modify your code from HWK 2 to implement a rupture source that starts from lon = 95.66E, lat = 2.61N and ends at lon = 93.07E, lat = 5.70N with a rupture speed of 2 km/s. Compare snapshots of the wave-field in the Bay of Bengal and the Andaman Sea to compare the timing of the tsunami in Thailand, Sri Lanka and India.

Table: Locations and tsunami arrival times for finite source

Location	lat (deg)	lon (deg)	arrival time (min)
Chennei(India)	$13.0$	$80.5$	$160$
Phuket(Thailand)	$7.5$	$98.0$	$90$
east-coast Sri Lanka	$7.0$	$82.0$	$115$

Table: Locations and tsunami arrival times for a point source

Location	lat (deg)	lon (deg)	arrival time (min)
Chennei(India)	$13.0$	$80.5$	$200$
Phuket(Thailand)	$7.5$	$98.0$	$125$
east-coast Sri Lanka	$7.0$	$82.0$	$150$
