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.

Recent earthquakes under Loihi volcano (Hawai'i)
Since late May, the volcano hidden beneath the Pacific south of Big Island has been showing markedly increased seismic activity. Several earthquake swarms were detected under the volcano.

A magnitude 4.2 earthquake was detected at Loihi volcano on 25 November. We will wait and see if the Hawaiian Volcano Observatory has any more information on this.
mer., 12 sept. 2001, 06:00
An earthquake swarm occurred at Loihi during 10-11 September and two 13 September earthquakes may have also been part of the swarm. The two later earthquakes occurred at 0311 and 0839 and had magnitudes of 4.9 and 4.4, respectively. Most of the earthquakes from 10-13 September were ~12 km deep and located slightly S of the summit of the volcano.

On 10 September an earthquake swarm began at Loihi. The swarm began with a M 5 earthquake and was followed by M 3.5-4.5 earthquakes until at least 11 September. This was the most severe swarm at Loihi since July 1996, when the summit collapsed.
