Kama'ehuakanaloa volcano (Hawaiian Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 13 July-19 July 2022 (Continuing Activity)

10:00 AM | AUTORE: VN
An earthquake swarm began at Kama'ehuakanaloa at about 0200 on 16 July and was characterized by seismic tremor accompanied by pulses of seismic energy every 15-20 seconds. The pattern of elevated seismicity continued through at least 1453 on 17 July, the posting time of the HVO's information statement. The report also noted that around 24 earthquakes in the M 1.8-3 range were recorded during 0130-0600 on 17 July.
The Scientist-in-Charge stated that the seismicity was likely the result of magma movement beneath the seamount, but there were no show signs of an imminent eruption. The most recent swarm was recorded on 11 May 2020 and consisted of 18 events in the M 3-3.9 range. The Volcano Alert Level and the Aviation Color Code both remained at Unassigned; there are no working monitoring instruments on the volcano so information is based on and-based seismometers.
