Big Earthquake Strikes Alaskan Islands, Triggers Tsunami Warning

Tsunami Warning
© OurAmazingPlanet
A magnitude 6.8 earthquake struck Alaska's Aleutian Islands in the wee hours of the morning today (Sept. 2), prompting a tsunami warning in the Pacific Ocean that was then canceled about an hour later.

The earthquake, originally reported to be a 7.1 magnitude, was later revised down by the U.S. Geological Survey. It occurred in the Fox Islands, about 1,030 miles (1,658 kilometers) from Anchorage at 6:55 a.m. EDT (1:55 a.m. local time).

The rupture occurred about 22 miles (35 km) below the Earth's surface. The Aleutian Islands are no strangers to the Earth's rumblings, as they are part of the seismically and volcanically active Pacific Ring of Fire.

The tsunami warning was issued initially, but no tsunami waves were recorded and the warning was rescinded.

The island chain's Cleveland Volcano has recently been stirring, growing a new lava dome atop its peak.

Smoke rises from the collapsed CTV Building on February 22.
A shallow magnitude 4.9 earthquake has rocked Christchurch early this morning, GNS Science reports.

The quake struck at 3.29am, and was centred 10km east of Lyttelton, off the end of Godley Head, at a depth of 6km.

GNS Science said the quake could have caused minor damage, and had reports it was felt as far north as Hamner Springs and as south as far as Timaru.

Orion said all power had remained connected following the quake.

Christchurch residents turned to Twitter to share their experiences.

New quake: The epicentre of this latest earthquake, measuring 3.4, was just four miles from Mineral, where last week's 5.8 quake started
Central Virginia has been shaken by another aftershock from last week's earthquake that rattled the East Coast.

The U.S. Geological Survey reported a 3.4 magnitude aftershock at 5.09am this morning.

The epicentre was four miles south-southeast of Mineral, the town that was the epicentre of last Tuesday's 5.8-magnitude earthquake.

More than 20 aftershocks ranging from 4.5 to 1.8 have followed the earthquake.

US: Earthquake may have exceeded Virginia nuke plant's safeguards

The earthquake that prompted the shutdown of a Virginia nuclear power plant last week may have been more severe than the plant's reactors were designed to withstand, federal regulators said.

The revelation is likely to put increased pressure on the Nuclear Regulatory Commission (NRC) to quickly implement a series of safety recommendations intended in part to protect plants from major natural disasters like earthquakes.

NRC said Monday that its preliminary analysis indicates that the ground motion caused by the magnitude-5.8 earthquake near the North Anna Power Station in Louisa County, Va., exceeded the maximum level the two reactors at the plant were built to handle.

But the commission noted in a statement Monday that "data is still being collected and analyzed to determine the precise level of shaking that was experienced at key locations within the North Anna facility."
