Jackson Ridge volcano

Updated: Dec 9, 2022 19:57 GMT -
submarine volcano -3100 m / -10171 ft
North Gorda Ridge, NE Pacific, 42.15°N / -127.05°W
Current status: normal or dormant (1 out of 5)
Last update: 12 Dec 2021 (Smithsonian / USGS Weekly Volcanic Activity Report)

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.

Background

The 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.

Jackson Segment volcano (Gorda Ridge) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 April-17 April 2001 (New Activity / Unrest)

Scientists from NOAA used the T-phase Monitoring System to search for megaplumes from a possible eruption of the Jackson Segment of the Gorda Ridge that began on 3 April. They did not find evidence of a plume after collecting 25 vertical hydrographic casts during 11-16 April. Two bottom camera tows were also collected, but the film had not been developed at the time of this report. ... Read all

Jackson Segment volcano (Gorda Ridge) - Smithsonian / USGS Weekly Volcanic Activity Report for 4 April-10 April 2001 (New Activity / Unrest)

At about 1800 on 3 April an underwater eruption may have occurred at the Gorda Ridge. Volcanic seismicity in the form of T-waves was detected coming from the Gorda Ridge ~200 m W of the S coast of Oregon. The signals were detected at seismometers maintained by NOAA's Pacific Marine Environmental Laboratory (PMEL). ... Read all
