In August 1989, an earthquake sequence including ten events with 6.3≥M≥5.5 in the first two days produced widespread ground deformation in the Dôbi graben of central Afar. Numerous surface breaks with complex geometry, including fresh scarplets with vertical throws up to 30 cm high and open fissures...
