SAN JOSE MINE, Chile -

Florencio Avalos, the first of 33 miners to be rescued, has surfaced after 69 days underground.

He stepped out of a rescue capsule amid sobs from his young son and received a bracing bear hug from Chilean President Sebastian Pinera.

Avalos smiled widely as he hugged rescuers, then Pinera, as his wife, two sons and father looked on. His seven-year-old son Bairo sobbed, as did Chile's first lady, Cecilia Morel.

Then Avalos was escorted into a medical triage centre for the first of a battery of tests.
