After several weeks of tremors and steam, Alaska's Mount Redoubt volcano has erupted -- sending ashes more than 9 miles into the sky.

These photos were taken before the 10,000 plus foot volcano first erupted late Sunday.

The volcano -- located about 100 miles southwest of Anchorage -- had been showing signs of a pending eruption for about two months. So far Anchorage has been untouched by harmful volcanic ash.

John Power of the Alaska Volcano Observatory:

(SOUNDBITE) (English) JOHN POWER, SENIOR SEISMOLOGIST FOR THE ALASKA VOLCANO OBSERVATORY SAYING:

"What we've seen at Redoubt over the past few days is a marked build up in earthquake activity, earthquake center directly beneath the summit of the volcano. Beginning at 10.38 pm last night we began to have explosive activity. At this time we've recorded four separate explosive events."

Officials at the observatory say the volcano is still unstable -- and further eruptions are likely
