The disasters crippled communications and damaged roads — problems that are also complicating efforts to bring aid to the city of Palu and other affected areas.
Communications are still down to some of the hardest-hit regions on the island of Sulawesi. "This is already a tragedy, but it could get much worse," says one aid official.
Relief agencies are having trouble reaching stricken areas, setting off looting of stores and aid supplies. The death toll from the tsunami and quake could rise further, officials warn.
The 7.5 magnitude quake, with an epicenter about 50 miles north of Palu, was just six miles deep. A tsunami later caused damage in two cities, according to Indonesian officials.
Damaging aftershocks continue to shake the island of Lombak, which suffered a deadly earthquake on Sunday. Rescue workers are struggling to reach the injured in some remote areas.
At least 82 people are dead after a 7.0 magnitude earthquake struck the northern part of the island on Sunday. It's the second powerful quake in a week to hit the region.
Following the funeral of a local resident killed by a crocodile after apparently straying into a local wildlife sanctuary, the mob slaughtered nearly 300 of the reptiles.
Rescuers say only 18 survivors have been found so far. The boat capsized late Monday afternoon during Eid al-Fitr, the Muslim holiday marking the end of the holy month of Ramadan.
