2018 Hawaii earthquake
6.9-magnitude earthquake in Hawaii
On May 4, 2018, an earthquake with a magnitude of Mw 6.9[5] struck Hawaii island in the Hawaii archipelago at around 12:33 p.m. local time.[6] The earthquake's epicenter was near the south flank of Kīlauea, which has been the site of seismic and volcanic activity since late April of that year.[7] According to the United States Geological Survey the quake was related to the new lava outbreaks at the volcano,[8] and it resulted in the Hilina Slump moving about two feet.[9] It was the largest earthquake to affect Hawaii since the 1975 earthquake, which affected the same region,[10] killing two people and injuring another 28.[11]
The earthquake had a maximum strength on the Mercalli intensity scale of VIII (Severe).[12] The earthquake was preceded by a smaller event, measuring 5.4, that was felt across the island and as far away as Oahu.[13]
The earthquake produced a minor tsunami that reached a maximum height of 40 cm (15.7 in.) in Kapoho, 20 cm (7.9 in.) in Hilo and 15 cm (5.9 in.) in Honuapo.[14]
