USA, Alaska – M 5.8 – Weak and deep earthquake near Alaska’s Mount Redoubt volcano

Earthquake Report comment :
The hypocenter (depth) of this weak earthquake was measured at a comfortable 143 km.
It was well felt at the other side of the Cook Inlet, although people reported only weak to light shaking.
Most of the earthquakes in this area (Lake Clark and further north) have a deep hypocenter.
The Pacific plate subducts the North American plate at a speed of approx. 70 mm (25 in.) / year.

Lake Clark National Park and Preserve was created to protect scenic beauty (volcanoes, glaciers, wild rivers and waterfalls), populations of fish and wildlife, watersheds essential for red salmon, and the traditional lifestyle of local residents.
Iliamna and Redoubt are two active volcanoes in Lake Clark National Park. Iliamna has not erupted in historic time, but is frequently  seen steaming from its summit fumaroles. Redoubt’s most recent eruptive period occurred during the spring of 2009. Redoubt dusted the region with volcanic ash and sent lahars (mudflows) down the Drift River. Both volcanoes are continuously monitored by the Alaska Volcano Observatory.
