Grandfather of Baby Girl Trapped for Hours in Rubble After Japan Quake Says He Wept After Her Rescue

She was trapped during the 1st of 2 deadly quakes in Japan this week.

Baby Miku was rescued six hours after the first quake hit Thursday. She was plucked out of the wreckage and gingerly cradled from rescuer to rescuer, surviving unscathed.

The baby's grandfather told ABC News' Matt Gutman he knew she was alive because he reached in and touched her, and she grabbed his hand. He said she wept when she was rescued.

Miku's family told ABC News they lost everything in the quake, but they also said they have everything -- their family.

Miku's family is one of many who are now homeless in southern Japan after two powerful earthquakes killed at least 41 people Thursday and Saturday.

The Associated Press said today that 180,000 people are seeking shelter and at least 90 buildings were destroyed.

The epicenter of Saturday's earthquake was about 8 miles northwest of Thursday's quake.
