The shock was centered 21 km us southwest of Puakō and 21 km on north of Kailua-Kona, Hawaii, just offshore of the Kona Airport, at a depth of 38.2 km mi on. It produced several aftershocks, including one that measured a magnitude of 6.1 seven minutes after the main shock. The Pacific Tsunami Warning Center measured a nondestructive tsunami of 4 in cm flip on the coast of the Big Island.http://www.mauiweekly.com/localnews/story2796.aspx Strong Quake Rocks Hawaii October 19, 2006 Local News October 5, 2007 dead https://web.archive.org/web/20070928175711/http://www.mauiweekly.com/localnews/story2796.aspx September 28, 2007 Maui Weekly Tectonic setting The island of Hawaii is affected by earthquakes related to three main causes. Some are associated with the movement of magma and tend to be shallow focus (less than 5 km depth). The largest earthquakes are those caused by overall gravitational spreading of the volcano, whether within the volcano's flanks or at the base of the volcanic pile. They tend to have focal depths in the range 5 to 13 km. The final group of earthquakes are those caused by flexure of the oceanic lithosphere underlying the island as a result of loading by the volcano. The type of stresses within the flexing lithosphere depends on depth relative to the neutral surface, with radial compression and associated tangential tension below about 22 km and radial tension and tangential compression above that level. Earthquakes of this type can have focal depths as deep as 60 km. Lithospheric flexure under the Hawaiian volcanic load: Internal stresses and a broken plate revealed by earthquakes Klein F.W. 2016 Journal of Geophysical Research: Solid Earth 121 4 2400–2428 10.1002/2015JB012746 2016JGRB..121.2400K free Earthquake The earthquake had a hypocentral depth of 38.2 km and a focal mechanism of normal faulting. The depth shows that it was in the mantle lithosphere, beneath the neutral surface with a mechanism consistent with tangential tension. The largest aftershock was significantly shallower at 18 km and had a focal mechanism of reverse faulting. The depth and mechanism are consistent with tangential compression above the neutral surface. Modified Mercalli Intensities were VII–VIII (Very strong–Severe) on the western side of the island of Hawaii, and VI (Strong) on the eastern side of Maui. Intensity V (Moderate) shaking was felt all the way to Oahu, where patches of moderate damage were reported.

The most severe damage caused by the earthquake was focused on the north and western sides of the island of Hawaii. Damage was also quite heavy on the eastern side of Maui, and minor damage spread all the way out to western Oahu, 170 mi km away from the earthquake's epicenter. On the Big Island, many houses had large cracks and broken windows, and at least 61 buildings were destroyed and red-tagged by officials. Almost all houses in west Hawaii reported extensive internal damage but most avoided significant structural damage, the reason being that most of the buildings in the area around the epicenter of the earthquake have been built in the last few decades and are well constructed. Even so, over $200 million in damage occurred.http://www.insurancejournal.com/news/west/2006/10/27/73645.htm Hawaii County Cuts Red Tape for Big Island Repairs October 27, 2006 October 5, 2007 Associated Press The largest and most luxurious hotels on the Island of Hawaii also happened to be clustered within 10 mile in of the earthquake's epicenter along the Kohala coast. The 1965 Mauna Kea Beach Hotel had its entire south end collapse, and the hotel's top floor was considered "destroyed." The hotel closed on December 1 after a month-long inspection revealed that the building was unsafe and in danger of collapse. After a $150 million renovation, the hotel had a soft reopening on December 20, 2008, and officially reopened in March 2009.https://www.hawaiimagazine.com/blogs/hawaii_today/2008/11/17/Mauna_Kea_Beach_Hotel_new_reopening_date Mauna Kea Beach Hotel announces new reopening date Paiva Derek November 17, 2008 Hawaii Magazine February 25, 2019 The Hapuna Beach Prince Hotel was temporarily evacuated after the earthquake due to structural damage, broken glass and flooding caused by broken water pipes. The Surety Kohala Corporation assessed the structural integrity to their Kohala Ditch, which functioned as a tourist attraction for 10 years. Many roads and bridges collapsed or had deep cracks, and clean-up crews had to work for days to remove debris from the countless landslides. Many landmarks on the island were greatly affected. The Kalahikiola Congregational Church in Kohala was destroyed due to the collapse of the church's stone walls; the Hawi smoke stack, a relic of the old sugarcane trade, completely collapsed as well. The Hulihee Palace in Kailua Kona suffered extensive structural damage.Hawaiian Historic Site Damaged..., Associated Press, accessed November 3, 2006 Another popular tourist area, Kealakekua Bay, home of the white monument to Captain James Cook, was swept over by massive landslides that caused the entire bay and its surrounding areas to momentarily disappear in a thick cloud of brown dust.Continuing Landslides lead to closures and Kealakekua Bay https://web.archive.org/web/20080405063742/http://starbulletin.com/2006/10/27/news/story04.html April 5, 2008 , Associated Press, accessed November 3, 2006 Mauna Kea Observatory thumb|Cliff falling in Waipio Valley during the earthquake.

Power was restored to all HECO circuits by 1:55 am; however, there were isolated blackouts due to local problems, such as blown fuses. Power in Laie and Kahuku was not restored until 3 am. In Honolulu and Kahe, HECO generators shut down, and other generators tried to compensate, resulting in uneven loads on Oahu's electrical network and causing the system to shut down to prevent damage.
