Okmok Volcano in Alaska continues to produce explosions and ash plumes through a newly created vent and poses hazards to air travel in the area. Scientists are using a combination of seismic and GPS instruments on the ground and weather and radar satellites in space to track the progress of the eruption. Human visual observations are limited because airborne ash obscures a view of what is happening inside the volcano's 6-mile-diameter caldera and the area is too hazardous to enter.
