(REUTERS) — A powerful 7.6-magnitude earthquake rocked Costa Rica on Wednesday, rattling buildings, cutting power in areas of the capital and triggering a tsunami warning.

Residents of San Jose said phones went down, electricity poles rattled on the streets and water flowed out of pools during the quake, but the Red Cross said no casualties had been reported so far.

“It was terrible. I was on the third floor, I had never felt anything like it,” said Stephanie Gonzalez, a 25-year-old masters student in the capital.
