Magnitude-4.0 Earthquake Near Maunaloa Road Unrelated to Volcanic Activity

A magnitude-4.0 earthquake occurred near Maunaloa Road on November 30, 2023, at a depth of 13 miles, with no relation to volcanic activity, as confirmed by the Hawaiian Volcano Observatory. Approximately 130 individuals reported feeling the earthquake in various regions across East Hawaiʻi, although it had no impact on local volcanoes.

On Saturday, November 30, a magnitude-4.0 earthquake struck 11 miles west-northwest of Volcano on the Island of Hawaiʻi at a depth of 13 miles beneath the surface, prompting reports from residents in various regions. Occurring at 8:40 a.m., the earthquake was situated south of Maunaloa’s Northeast Rift Zone but was confirmed by the Hawaiian Volcano Observatory as not linked to magmatic activity. This event did not appear to affect Maunaloa or Kīlauea volcanoes.

The United States Geological Survey recorded approximately 130 reports from individuals who felt the quake during the initial hour post-event, primarily from East Hawaiʻi areas, including the Puna district, Hilo, and the Hamakua coast; as well as in North Kona and southern Kaʻū communities. Such responses highlight the earthquake’s perceptibility across a substantial area, despite the lack of significant geological implications related to volcanic activity.

The topic of earthquakes and their relation to volcanic activity is significant, particularly in regions like Hawaiʻi where the geological landscape is dominated by volcanic formations. The Hawaiian Volcano Observatory plays a crucial role in monitoring seismic activity and volcanic behavior. Understanding the distinction between tectonic earthquakes, which can occur independently of volcanic activity, and those associated with magma movement is essential in assessing potential risks to communities and the environment.

In conclusion, the magnitude-4.0 earthquake recorded near Maunaloa Road on November 30 was a tectonic event unrelated to volcanic processes, according to the Hawaiian Volcano Observatory. Despite being felt by numerous residents across various districts, the earthquake posed no threat to the nearby Maunaloa or Kīlauea volcanoes, thus reassuring the public regarding geological safety.
