It was hit by the earthquake in the form of groundshaking and surface rupture. The slopes around this city failed catastrophically. On one side, a rick avalanche buried the Beichuan middle school (700 casualties), and on the other side another large landslide covered a large part of the city (1600 casual- ties). Further downstream, a major landslide caused the damming of the river, resulting in the city centre being flooded. After several months, the destabilised slopes around the city were reactivated during a rainstorm event, and debris flows covered the ruins of A rick avalanche buried the Beichuan middle school (700 casualties) part of the city.
