HONOLULU (HawaiiNewsNow) - A 5.7-magnitude earthquake struck Hawaii Island on Friday morning, producing strong shaking felt across the state. The Hawaii Department of Education investigated reports of structural damage at two Hawaii Island schools, but determined the cracks were not due to the quake. Residents on the Big Island say the quake shook items from shelves and threw pictures from walls. “I was sitting in my truck and I thought there was something wrong with my truck,” said Hawaii Island community leader Ikaika Marzo. “My family on Kauai said they felt it, too.”The quake comes amid a period of increased seismicity on Hawaii Island linked to Kilauea.
