Two strong earthquakes that struck eastern Indonesia overnight killed at least one person and injured 45 other people, a senior health ministry official said Monday. Dozens of buildings were reportedly destroyed or damaged. The first quake, with a magnitude of 6.4 struck late Sunday, just off Sumbawa island. Several hours later, a powerful aftershock hit the same region. "Everyone panicked, they were running from their houses, some to the hills," said Agung Prasetyo, a local police officer, adding that the ground shook violently for around 30 seconds.
