November 1, 2010 – Big Island of Hawaii
It was a seismically active weekend on Hawaii Island, and it all started with a strong jolt on Friday.
Many on the Hamakua Coast were shaken by a 4.1 magnitude temblor shortly after 3 p.m. on Friday. No injuries or damage was reported in the region.
From the USGS website:
== PRELIMINARY EARTHQUAKE REPORT ==
U.S. Geological Survey, Hawaiian Volcano Observatory
Version #2: This report supersedes any earlier reports of this event.
This event has been reviewed by a seismic analyst.
This earthquake was felt.
A light earthquake occurred at 3:09:25 PM (HST) on Friday, October 29, 2010 .
The magnitude 4.1 event occurred 8 km (5 miles) ENE of Kukuihaele.
The hypocentral depth is 35 km (22 miles).
That was only the beginning. Although the Friday shake-up was by far the most powerful, the island still had some rumbling to do. According the Hawaiian Volcano Observatory:
“Ten earthquakes were strong enough to be located beneath Kilauea volcano on south flank faults including a magnitude-3.6 earthquake that occurred just before noon yesterday. Seismic tremor levels remained elevated and variable.”
UPDATE: No sooner was this published, than another Civil Defense message reached our desk. At 11:44 p.m. on October 31st, a 3.5 magnitude earthquake occurred 8 miles South Southwest of Honoka’a. No tsunami was generated, no damage was reported, says Hawaii County Civil Defense.
