Tremors shake Alaska volcano as state awaits eruption

Mount Redoubt experienced "high-intensity" volcanic tremors this morning but has not erupted, scientists at the Alaska Volcano Observatory report.

The first tremor event was recorded from 2:44 through 2:50 a.m., volcanologists said. A second, short burst occurred at 8:47 a.m. (1:47 p.m. EST).

"Since then a series of small, repeating earthquakes is ongoing," the observatory reports.

The 10,197-foot mountain 106 miles southwest of Anchorage has been under close observation for several days due to elevated seismic activity and the release of steam and gases near the summit.
