ALASKA VOLCANO ERUPTS FOUR TIMES !

Mount Redoubt volcano in the US state of Alaska has erupted, sending a cloud of ash 15km (50,000ft) into the air.
The volcano, 166km (103 miles) from Anchorage, erupted late on Sunday, with three more explosions early on Monday.
The Alaska Volcano Observatory has issued a red alert, meaning an eruption with significant amounts of ash is imminent or under way.
Forecasters at the National Weather Service said they expected fine ash to begin falling later on Monday morning.
"The ash cloud went to 50,000 feet and it's currently drifting towards the north-east," Janet Schaefer, a geologist at the Alaska Volcano Observatory told the Associated Press (AP).
It is expected the ash cloud will pass west of the city of Anchorage, moving towards Willow and Talkneetna, two communities near Mount McKinley.
Dave Stricklan from the National Weather Service told AP he expected the ash fall to be "just kind of a light dusting".
Most of the ash probably fell down the side of Mount Redoubt, he said.
The observatory warned in late January that an eruption was likely after the volcano showed signs of activity.
Mount Redoubt, which stands 3,100m (10,200ft) high, last erupted over a four-month period from 1989 to 1990.
