Ibiza
Earthquake data (USGS): t0: 18:44:19 GMT, 21 may 2003
USGS: epicenter 36.96°N, 3.63°E, M=6.9, hf=12 km
Borerro: epicenter 36.90°N, 3.71°E, M=6.8, hf=10 km, strike=56°

3. Euristic formula for the run-up used by Pelinovsky and Ivanov: but no proofs available!

4. Ellipsoidal deformation
hf = 12 km a
56° b
(Pelinovsky et al., 2001)
a = 34 km
b = 12 km
Coordinates: model gridpoints

5. Gaussian*cosine deformation
a1= km-1
a2 = km-1
b1 = km-2
b2 = km-2
= 0
= 56°
Coordinates: model gridpoints
