Over 840 people are now confirmed to have died in Friday’s Indonesian earthquake and tsunami, and nearly 50,000 more have been displaced in the disaster’s aftermath. The death toll is expected to rise as many coastal towns remain inaccessible and rescuers have been unable to assess the damage. The 7.5-magnitude quake hit Friday night, creating a tsunami that swept terrifying 20-feet waves onto parts of the coastline. Many buildings collapsed and rescuers are still working to free survivors. President Joko Widodo urged a “day and night” effort to rescue them. Volunteers have begun burying victims in a mass grave.
