Apr. 4—A 4.3-magnitude earthquake was recorded beneath Mauna Loa on Hawaii island this morning, according to the U.S. Geological Survey, and could be felt as far away as Kauai.

The earthquake occurred at 11 :15 a.m. today in the vicinity of the southeastern flank of Mauna Loa but was not large enough to generate a tsunami.

Its epicenter was three miles northwest of Pahala near Wood Valley at a depth of five miles below sea level.

A second temblor, which registered 3.9 magnitude in the same area, preceded the larger one at 11 :02 a.m.

The USGS received more than 130 reports from people saying they felt weak to light shaking within the first hour of the larger quake across the islands and one report from Kauai.

"At this time, we have not observed any changes in activity at Mauna Loa or Kilauea as a result of this earthquake. Please be aware that aftershocks are possible and may be felt. HVO continues to monitor Kilauea and other Hawaiian volcanoes for any changes, " said Hawaiian Volcanoes Observatory scientist-in-charge Ken Hon in a statement.

A swarm of earthquakes was previously recorded on March 29 beneath the northwest flank of Mauna Loa.
