Mass graves were being readied Monday for hundreds of victims of an Indonesian quake-tsunami as authorities battled to stave off disease and reach desperate people still trapped under shattered buildings.
With the death toll already at over 830 and expected to rise further on the devastated island of Sulawesi, there were growing questions about why an early tsunami-warning system had notbeen working for years.
The strong 7.5-magnitude quake struck Friday, toppling buildings and sending walls of seawater crashing into Palu, a city of about 350,000.
Exhausted survivors scoured make-shift morgues for loved ones, and authorities struggled to dig out the living or assess the scale of the devastation in more remote regions beyond Palu.
