HULHULE-MALE’ BRIDGE PROJECT

EIA for the proposed Hulhule-Male’ Bridge Project
and the only land area includes the project site Maldives islands consist of 26 natural atolls and
more than 1,000 coral islands.
Looking from a regional perspective, the region is located in the mid-oceanic ridge of Carlsberg
and oceanic ridges of Ninety East. The mid-oceanic ridge of Carlsberg is the main seismogenic
structure within the region, with the structural condition that may cause earthquake of magnitude
7.5 and the fracture (Figure 4.51) stretching along NS direction within the region is predicted
that it may cause the earthquake of magnitude 7.5. It should be considered in the seismic hazard
analysis. The earthquakes in the mid-oceanic ridge of Carlsberg almost all distribute along its
direction over the ridge axis, and most are shallow ones. So, it should be outlined along the midoceanic
ridge of Carlsberg when dividing potential earthquake source region.

Coral islands in near-field region basically are covered by calcareous sands, calcareous sand
containing coral debris, loose coral rock mixed with sands and other loose materials, with
uneven thickness that is various from a few to several tens meters. Underlying them are loose
