00:00A powerful earthquake just rocked Alaska's Aleutian Islands,
00:03and fears of a tsunami are rising fast.
00:06At 1 a.m. local time, a 5.2-magnitude quake hit near Nikolsky.

00:21Reports say people are on edge, watching the waves and waiting for updates.
00:25The shaking came from the Aleutian megathrust.

00:50But each new quake reminds everyone how powerful nature really is.
