For 100 days, they combed more than 2,500 square miles of ocean.

Emergency workers are continuing to comb through underground car parks and tunnels in the hope of finding survivors and recovering bodies.

Efforts have been made to collect unexploded weapons - like in Gorero, a small village off the side of the main road to Adwa, where officials have combed farms and fields.
