Quake that shook Big Island was biggest in Hawaii since 1975

PUNA, BIG ISLAND (HawaiiNewsNow) - The 6.9-magnitude that shook the Big Island on Friday and was felt as far away as Oahu was the strongest tremor in Hawaii in 43 years.

The Friday quake happened about 12:30 p.m. and was centered on the south flank of Kilauea, which has been erupting into Leilani Estates since Thursday.

Chip McCreery, director of the Pacific Tsunami Warning Center, said the quake was the largest to strike the Big Island since November 1975, when a tremor centered two miles off Kalapana Beach was measured at a magnitude 7.2.

That quake caused a local tsunami that killed two people and injured several others.

Another pair of quakes in 2006 — the largest of which was a magnitude 6.7 — were centered off the northwest coast of Hawaii island and caused an island-wide power outage on Oahu that lasted 19 hours.

The strongest quake ever to hit Hawaii was a 7.9-magnitude. It was recorded on April 4, 1868.
