Geologists in Alaska say the Mount Redoubt volcano may be getting ready to awaken after being relatively quiet for more than a month.
Scientists at the Alaska Volcano Observatory say activity at the volcano about 100 miles southwest of Anchorage suggests a significant explosive event is likely with days — although that's not certain.
Mount Redoubt's last explosive event was April 4, when it blew a plume of gritty volcanic ash more than 8 miles into the air.
Geophysicist John Power says shallow earthquake activity has been increasing at the volcano since Saturday.
Similar seismic activity was observed before eruptions this year and during the volcano's last major active period in 1989-90.
