ANCHORAGE - The swarm of small shallow earthquakes that began April 5 at the Redoubt volcano has ended, and the shaking returned to background levels.

Eruptions from the 10,197-foot volcano early last year disrupted air travel, dusted Anchorage with ash and sent a mudflow that partially flooded the Drift River Oil Terminal.
