Robert Dziak at the NOAA/Pacific Marine Environmental Laboratory in Newport, Oregon reported that 10 Hz band-limited tremor was detected from the Volcano Islands area after a 6 month hiatus (BGVN 24:11 and 24:12). The current episode of signals began at 0800 UTC on 13 June, but were loudest at 0100-0200 UTC on 14 June. The tremor tracks to presumed submarine volcanism at an uncertain volcano.
