2 large earthquakes at Kilauea felt as far away as Oahu

PUNA, BIG ISLAND (HawaiiNewsNow) - Two large earthquakes shook the Big Island on Friday as Kilauea eruptions continued.

While the quakes were centered on Kilauea south flank, they were felt as far away as Hilo and Oahu.

The second quake was a monster 6.9-magnitude that happened about 12:37 p.m.

The temblor was the largest in Hawaii since 1975, and did generate small tsunami waves around the Big Island, triggering sea fluctuations that ranged from 8 inches in Hilo to 16 inches at Kapoho, Hawaii County Civil Defense said.

Dr. Charles McCreery, director of the Pacific Tsunami Warning Center, said the small tsunami waves did not pose any threat but underscore the importance of vigilance as the Kilauea eruptions continue.

Dramatic video shows people fleeing from buildings during the quake and screaming as they felt the ground shaking.

Talmadge Magno, administrator of Hawaii County Civil Defense, said there were no immediate reports injuries from the quakes. Damage appeared to be limited, but Magno said there were several landslides on the Hamakua Coast.

The quake came an hour after a slightly weaker quake — a 5.4 magnitude — rocked the Big Island about 18 kilometers southwest of Leilani Estates, the U.S. Geological Survey reported.

Residents across the Big Island and as far away as Oahu said they felt shaking.

Doris Matsumoto lives on the 10th floor of a highrise on Aala Street. She was sitting on her sofa reading a book when the first quake hit.

"I was holding my book and my hand and my book was shaking," she said.

Dorothy Suchar was in her apartment on Young Street.

"I was laying on my bed talking to my friend and all of a sudden my bed started moving just slightly. When the tremors got even stronger it got even stronger," she said.

People also took to social media to document their experiences.

"Things fell off our shelves in Hilo," Merle Gornick posted on Facebook. "My heart is still pounding!"

Axel Kratel also wrote, "Massive Earthquake, we have broken glass in the house, and we are in lower Hamakua, must have been much worse in Puna."

And on Twitter, Andrew Buttrey said, "Felt some shaking on the other side of the island in Kalaoa also."
