USGS HVO Press Release — Magnitude-5.0 Aftershock Occurred on Northwest Side of Hawai‘i Island
A magnitude-5.0 earthquake was recorded by the U.S. Geological Survey's Hawaiian Volcano Observatory on November 23, 2006 at 9:20 a.m. HST.
It was located 6 km (4 miles) offshore and northwest of Kīholo Bay or 18 km (11 miles) southwest of Waikoloa Village at a depth of 38 km (23 miles).
The latest rupture was very close to the same region as the magnitude-6.7 earthquake that occurred on October 15, 2006 that caused an estimated $200 million in damages. The Hawaiian Volcano Observatory's seismic network has recorded nearly 160 aftershocks from the magnitude-6.7 October 15 earthquake; the aftershocks continue.
The earthquake was felt as far away as O‘ahu. The U.S. Geological Survey's Community Internet Intensity Map (http://pasadena.wr.usgs.gov/shake/STORE/X21672_06/ciim_display.html) displays the highest shaking intensities again on the northwest part of the Big Island.
Today's aftershock had no immediate effect on the continuing eruption of Kīlauea Volcano or on Mauna Loa or Hualālai.
Daily updates about ongoing eruptions, recent images and videos of summit and East Rift Zone volcanic activity, maps, and data about recent earthquakes in Hawaii are posted on the HVO website at https://volcanoes.usgs.gov/observatories/hvo.
