The 2006 Kīholo Bay earthquake occurred on October 15 at 07:07:49 local time with a magnitude of 6.7 and a maximum Mercalli intensity of VIII (Severe).The shock was centered 21 kilometers (13 mi) southwest of Puakō and 21 km (13 mi) north of Kailua-Kona, Hawaiʻi, just offshore of the Kona Airport, at a depth of 38.2 km (23.7 mi).
The 1868 Hawaiʻi earthquake was the largest recorded in the history of Hawaiʻi island, [3] with an estimated magnitude of 7.9 M fa [1] and a maximum Mercalli intensity of X (Extreme). The earthquake occurred at 4 p.m. local time on April 2, 1868, and caused a landslide and tsunami that led to 77 deaths.
At each collapse event the floor of the caldera dropped several meters and there was a magnitude 5.2 to 5.4 earthquake. Between each collapse event, an escalating swarm of earthquakes would occur. Notably, more than 700 earthquakes of a magnitude 4.0 or higher occurred each day during the collapse period. [28]
Today, earthquakes are monitored by the Hawaiian Volcano Observatory run by the USGS. Hawaii accounted for 7.3% of the United States' reported earthquakes with a magnitude 3.5 or greater from 1974 to 2003, with a total 1533 earthquakes. Hawaii ranked as the state with the third most earthquakes over this time period, after Alaska and California ...
The earthquake caused severe damage to roads and buildings on Adak including a crack 4.5 m (15 ft) in size, [6] however there were no deaths. [14] Two bridges and some oil and fuel-related structures at a dock were also destroyed there. [ 14 ]
