So far, at least 420 people are confirmed dead and 1,400 injured after a tsunami hit Indonesia on Saturday.
As of Tuesday afternoon, 154 people were also reported missing.
Adding to the human cost of the disaster is the property damage: More than 16,000 people are displaced and over 800 homes destroyed, according to the country's National Disaster Mitigation Agency.
Officials believe a volcanic eruption triggered an underwater landslide during a high tide, which then caused the tsunami's monster wave.
Authorities have warned residents more tsunamis could soon strike because of the undersea volcano's high activity.
