Jackson Ridge volcano
North Gorda Ridge, NE Pacific, 42.15°N / -127.05°W
Current status: normal or dormant (1 out of 5)
The Jackson Segment is one of 5 principal submarine volcanic centers (or segments) that together form the Gorda Ridge spreading center, where extension is taking place to produce new oceanic crust. It is located more than 200 km off the coast of Oregon.
There are no confirmed eruptions in historic times, but it is likely that it has had activity during the past few thousands of years.

BackgroundThe first recorded activity took place in April 2001, when volcanic seismicity was detected by hydroacoustic monitoring. The seismicity indicated possible dike propagation to the south and was similar to that which was documented at the time of the eruption of a submarine lava flow from the adjacent North Gorda Ridge segment in 1996. The 2001 activity originated from the central axial valley of the Jackson Segment, near the "narrowgate" on the southern part of the segment. Later surveys, however, revealed no evidence for submarine eruptive activity in April 2001.
