estimated as 51-64 m (based on Fitchen, 1997,

about 64-80

Maldives
(after Belopolsky & Droxler, 2004):
Miocene unit M2 is estimated to represent
0.9-3.4 Myr of time; based on thickness pro-
portions, the FST is assumed to represent 25%
of this time, i.e. 0.22-0.85 Myr. Range of fall is
50 ms two-way travel time; estimated inter-
val velocity at this level is 2000 m s

, which
yields a range of fall of 50 m and rates of fall of
60-230

Shu'aiba of Safah

(after Boote & Mou, 2003,

FST of Upper Shu'aiba is estimated to occupy
0.57-1.28 Myr of time; the range of fall is
11.5-30 m. This translates into rates of fall of
9-53
