From Yahoo News:
Hundreds had gathered in the pews of the San Clemente church on Wednesday — the day Roman Catholics celebrate the Virgin Mary's rise into heaven — for a special Mass marking one month since the death of a Pisco man.
With minutes left in the Mass, the church's ceiling began to break apart. The shaking lasted for an agonizing two minutes, burying 200 people, according to the town's mayor. On Thursday, only two stone columns and the church's dome rose from a giant pile of stone, bricks, wood and dust.
