A very large earthquake with a magnitude of 8.7occurred nearby Nias Island of Indonesia on March 28,2005.
Although the magnitude of the earthquake was large,the scale of the induced tsunami was very small.This may be
due to the particular sea topography and the small amplitude of the uplift of the seabed. Strong ground motions
induced heavy casualties and damages to structures.Although the magnitude of this earthquake was much smaller
than that of December 26, 2004, the induced strong ground motions were much higher. The earthquake induced
widespread liquefaction and lateral spreading.This phenomenon was the primary cause of heavy damage to bridges
and buildings in Nias Island.
