KALAOA, Hawaii — Scientists say a weekend earthquake that struck Hawaii was not related to volcanic activity.
Researchers at the Hawaiian Volcano Observatory say the 5.3-magnitude earthquake Saturday was not caused by magma moving underground.
The scientists say the earthquake around 5 p.m. about 14 kilometres (more than 8 miles) northwest of Kalaoa was due to movement of the crust under the Big Island.
The observatory says the quake was located at a depth of about 15 kilometres (more than 9 miles), which is far deeper than a quake that might be caused by moving magma.
The U.S. Geological Survey says it received reports from residents who felt the earthquake across the island from Hilo to Kailua-Kona.
The observatory says 15 aftershocks were reported by Monday.
