(CNN) -- Officials will remove oil from two massive storage tanks near the base of erupting Mount Redoubt in Alaska, a spokesman said Friday.
As the volcano continues to spew ash across Alaska's Cook Inlet, U.S. Coast Guard officials said they will begin to transfer oil from the Drift River facility to get to a "safe" level.
Coast Guard Officer Sara Francis said the oil is being reduced to protect against "the potential threat by the volcanic activity" and the potential effect on the environment near the storage locations.
Francis said the workers will remove about 75 percent of the 6.3 million gallons of oil in the tanks.
Small, shallow repeating volcanic earthquakes indicative of lava dome growth are continuing at the rate of 3-4/minute. These earthquakes are most prominent on station REF.
Cloudy conditions currently preclude views of the volcano in the AVO webcam.

The eruption of Redoubt Volcano continues. Over the past several days, the intensity of ash-production has decreased. Current observations indicate a lava dome is growing in the summit crater. Therefore, we are lowering the alert level and aviation color code.
The 2009 eruption is now characterized by continuous emission of steam, volcanic gas, and variable amounts of ash. These processes are occurring as effusion of lava in the summit crater produces a lava dome. While at this level of activity, trace amounts of ash and a perceptible volcanic haze layer may be intermittently present throughout south-central Alaska.
A growing lava dome is inherently unstable; a sudden dome collapse or explosion can occur with no warning and produce a more voluminous ash cloud that rises to elevations above 25,000 feet. If such an event is detected, AVO would issue appropriate warnings.

Another significant explosive event occurred at Redoubt Volcano at approximately 5:58 am AKDT (13:58 UTC). At this time, the cloud height is estimated to be 50,000 feet based on National Weather Service radar. The cloud is drifting to the southeast of the volcano. AVO seismometers indicate a lahar has developed in the Drift River Valley.

The eruption of Redoubt continues with varying intensity of ash and lava production from the summit crater. Additional significant explosive events with accompanying ash clouds, ash fall, and mudflows are possible and can occur with little or no warning. Visual, satellite, and seismic observations indicate that a lava dome is again forming in the summit crater.
The character of current seismicity suggests that a sudden explosive eruption is not imminent. Present levels of activity are emitting only a very minor amount of ash that poses a hazard of limited aerial extent. Consequently, AVO is lowering the Aviation Color Code to ORANGE and the Alert Level to WATCH. AVO will maintain 24/7 operations in order to quickly detect renewed significant explosive activity and other hazardous phenomena.
Intermittent views by the AVO web camera earlier today show a continuous plume composed primarily of water vapor and gas rising above the summit to less than 15,000 feet and drifting northeast.
