Johnson R H, 1976. Possible submarine volcanic eruption off southern California. Deep-Sea Res, 23: 265-267.

One hundred explosions over a period of about 40 minutes, possibly originating from a submarine eruption 400 km SW of Point Conception, California, were detected by hydrophones on October 7, 1972. Two seamounts, about 6 km south and 32 km east of the site, are within the position uncertainty and were considered the most likely sources of the signals (Johnson, 1976). The seamounts are at depths of 2825 and 2533 m, respectively.
