June 23 2014 - 8.0-Magnitude Alaska Earthquake prompts tsunami advisory for Pacific Coast -

7.9 hits Alaska’s Aleutian Islands, 6.9 strikes Kermadec Islands

Posted on June 23, 2014 by The Extinction Protocol

June 2014 – ALASKA – Authorities have downgraded the tsunami warning that was issued for parts of Alaska’s Aleutian Islands after a magnitude-8.0 earthquake. The earthquake was later downgraded to a 7.9 by the USGS. Monday’s quake generated small tsunamis, with waves of less than 7 inches, prompting the National Tsunami Warning Center to downgrade the warning to an advisory. Small waves are still expected along parts of the Aleutian Islands stretching from Unimak Pass to Attu, and officials advised people to stay off the beaches. The earthquake recorded at 12:53 p.m. Alaska Daylight Time was centered about 13 miles southeast of Little Sitkin Island or 25 miles north Amchitka Island, an area prone to earthquakes located about 1,300 miles southwest of Anchorage. There were several strong aftershocks, but no immediate reports of damage. The largest city near the epicenter is Adak, which has about 300 residents. –ABC News

6.9 magnitude strikes north of NZ: A magnitude 6.9 earthquake hit the Kermadec Islands, the northernmost group of islands in New Zealand territory, just after 7am this morning. It was followed by a 6.3 two minutes later and a 6.2 just after 8am. The quakes struck around 90km off the coast of Raoul Island, or just under 1000km from Whangarei, the US Geological Survey reports. The Pacific Tsunami Warning Centre says there is currently no risk of a tsunami from the earthquakes. Raoul Island is the northernmost inhabited outpost of New Zealand and is permanently manned. The island is no stranger to large earthquakes; a magnitude 7.6 hit in July 2011 and generated a small tsunami. A 7.4 hit later that same year in October. -TVNZ

8.0-Magnitude Alaska earthquake prompts tsunami advisory for Pacific Coast

The ABC7 Quake Cam shows an 8.0-magnitude earthquake that struck Alaska on Monday, June 23, 2014.

An 8.0-magnitude earthquake struck at 1:53 p.m. in Alaska, prompting a tsunami warning for the U.S. Pacific coast. A preliminary report indicated the quake was a 7.1 magnitude. That was revised minutes later to 8.0 by the U.S. Geological Survey.

The warning for Southern California was downgraded to a tsunami advisory by the National Weather Service.

The NWS reported that water was leaving the harbor of the city of Adak, Alaska, at 3:23 p.m. The Adak city manager confirmed to ABC News that water in the harbor was receding and people in that area were heading for higher ground.

The earthquake struck 244 miles southeast of Attu Station in Alaska, about 15 miles off Little Sitkin Island.

The earthquake occurred at a depth of 71.1 miles, according to the USGS.

Comment: The Aleutian volcanoes in Alaska are waking up and showing more activity than has been seen for decades in an already volatile region. The Pacific Ring of Fire has been quite active this year and will certainly be something to watch.
