Officials in China have warned that the death toll from this week's devastating earthquake could hit 50,000. State media say that all 58 counties and townships damaged by Monday's quake now have been reached.
Host Renee Montagne talks about rescue operations with NPR's Louisa Lim, who is in a hard-hit area about 50 miles from the provincial capital of Chengdu.
Lim says every building there has been flattened — not one is in tact — and a "particularly intense rescue operation" is under way at a chemical factory. The five-story factory collapsed and buried a hundred workers, and this morning there were signs of life inside.
