Tsunamialarm Alaska en Hawaï na aardbeving
Tsunamialarm Alaska en Hawaï na aardbeving.
Een krachtige aardbeving met een kracht van 7,2 heeft woensdag het weesten de Aleoeteneilanden getroffen en heeft voor een tsunamialarm gezorgd voor sommige kustgebieden van Alaska, zo heeft het Amerikaans Geofysisch Instituut (USGS) gemeld.
Het epicentrum van de om 12.30 uur Alaska-tijd gemeten beving lag op 200 km ten westen van Adak en op 2.098 km ten zuidwesten van Achorage. Er werd een tsunamialarm afgekondigd voor het deel van de westkust van Alaska tussen Nikolski en Attu. De inwoners werd gevraagd om weg te blijven van de kust en te wachten op instructies van de lokale autoriteiten.
Volgens CNN werd het tsunamialarm snel weer opgeheven. Nog volgens CNN was er geen onmiddellijke schade door de aardbeving. Luidens het Amerikaanse televisiestation MSNBC is er ook tsunamialarm voor Hawaï afgekondigd.

Powerful Magnitude 7 Quake Rocks Aleutian Islands.
ANCHORAGE, Alaska — A large earthquake rattled Alaska's seismically active Aleutian Islands, but there were no immediate reports of any damages or injuries.
The magnitude-7.2 quake struck at 11:30 p.m. Tuesday and was centered about 125 miles west of Adak in the island chain, according to a preliminary report by the U.S. Geological Survey.
A dispatcher with the Anchorage Police Department said he didn't feel the quake, some 1,300 miles away, and there were no reports of any injuries or damages.
The Aleutian Islands are a chain of more than 300 islands that extend southwestward from Alaska into the northern Pacific Ocean.
A tsunami warning was canceled early Wednesday for Alaska's coasts after officials determined waves from the earthquake posed no widespread destructive threat.
The earth's most active seismic feature, the circum-Pacific seismic belt, brushes Alaska and the Aleutian Islands, where more earthquakes occur than in the other 49 States combined.
The Andreanof Island sustained a magnitude 8.8 earthquake in March 1957 that caused very severe damage on Adak and Unimak Islands. A damaging tsunami was generated, and a wall of water 40 feet high smashed the coastline of Scotch Cap on Unimak Island. Sand Bay, near Adak, reported 26-foot waves inundated its shores.

Nieuwe aardbeving treft Aleoeteneilanden bij Alaska.
De Aleoeteneilanden voor de kust van de Amerikaanse staat Alaska zijn opnieuw getroffen door een aardbeving. Deze keer had de beving een kracht van 6,1 Mw. Twee dagen geleden was er al een krachtige aardbeving met een kracht van 7,2 Mw.
Het epicentrum van de aardbeving, die om 8.24 uur Belgische tijd plaats vond, was op 175 kilometer van Adak en op 2.098 kilometer van Anchorage gelegen op een diepte van 35 kilometer. Het Amerikaans instituut becijfert aardbevingen volgens de de schaal "moment magnitude (Mw)". Op deze schaal wordt een aardbeving met een kracht van 6,1 Mw beschouwd als krachtig.

Four quakes hit Alaska’s Aleutian Islands
Seismic activity begs closer look; aftershocks follow 7.2 temblor
ANCHORAGE, Alaska - Two significant earthquakes that shook Alaska's remote Aleutian Islands were followed Friday morning by two smaller quakes, but there were no reports of damage or injuries. The temblors probably were aftershocks of a magnitude-7.2 quake that hit the seismically active but sparsely populated island chain Tuesday along a dynamic fault line, said geophysicist Guy Urban of the West Coast and Alaska Tsunami Warning Center. "Maybe things are still moving around out there," he said. "The area is still settling." The magnitude-5.9 and 6.1 quakes struck about one minute apart Thursday. They were centered about 100 miles west of Adak in the island chain, according to a preliminary report by the U.S. Geological Survey.
'Unusual' activity
"There were two tonight and that was very unusual," said geophysicist Paul Huang of the tsunami warning center. "We're going to study this a little more closely." No tsunami warning was expected, he and Urban said. Magnitude 4.8 and 4.6 quakes struck 14 minutes apart Friday morning, Urban said. He said there have been no reports that any of the quakes this week were felt by people there.
The Aleutian Islands are a chain of more than 300 islands that extend southwestward from mainland Alaska into the northern Pacific Ocean. The earth's most active seismic feature, the circum-Pacific seismic belt, brushes Alaska and the Aleutian Islands, where more earthquakes occur than in the other 49 U.S. states combined.
