A powerful magnitude 7.7 earthquake struck off the coast of Indonesia's Flores region on Saturday, killing at least 20 people and causing severe damage to buildings and homes. The quake was followed by a tsunami warning that was later lifted after monitoring showed no significant sea-level changes.
