Cobb–Eickelberg Seamount chain : ウィキペディア英語版 | Cobb–Eickelberg Seamount chain The Cobb–Eickelberg Seamount chain is a seamount chain stretching from the Aleutian Trench in the north to Axial Seamount, the youngest volcano in the chain, which lies approximately 480 kilometres (300 miles) west of Cannon Beach, Oregon. The chain was created by the Cobb hotspot as the Pacific Plate drifted in a northwesterly direction, leaving a trail of seamounts in its wake. The most recent volcanic activity in the chain was at Axial Seamount on January 28, 1998, when a magnitude 4.7 earthquake was recorded in the area.〔(VolcanoWorld: Axial Seamount ) Retrieved 2007-09-14〕 Some features in the chain: *Cobb hotspot *Axial Seamount *Brown Bear Seamount *Cobb Seamount *Patton Seamount ==References==
