Weer kleine aardbeving in Groningen.
In de omgeving van Garsthuizen (Groningen) heeft zich vrijdagavond een kleine aardbeving voorgedaan. Volgens een medewerkster van het KNMI ging het om een beving van 2,2 op de schaal van Richter.

Ze zegt dat de beving waarschijnlijk niets te maken heeft met de aardschok van een week geleden bij Westeremden.

Over schade in Garsthuizen is nog niets bekend.

TOKYO — A 6.1-magnitude earthquake struck off the coast of northern Japan on Thursday, the Meteorological Agency said. There were no immediate reports of damage or casualties.

The quake hit Thursday morning off the coast of Miyagi, about 180 miles north of Tokyo, the agency said. It struck at a depth of about six miles.

The agency said there was no danger of a tsunami from the earthquake.

Masakazu Murakami, an official in charge of disaster management in Miyagi, said the quake caused no damage to utilities such as water, electricity, gas and telephone lines.

"I was in the office when the quake hit this morning. But I did not feel any tremors," Murakami said.

A police official in Miyagi said authorities there had not received any reports of damage or casualties. The official spoke on condition of anonymity, citing department policy.

Japan is one of the world's most earthquake-prone countries.

The most recent major quake in Japan killed more than 6,400 people in the western port city of Kobe in January 1995.

Experts believe Tokyo has a 90 percent chance of being hit by a major quake over the next 50 years.

Reuzengolven treffen Papoea-Nieuw-Guinea
09-12-2008 15:22

PORT MORESBY (ANP) – De noordelijke kust van Papoea–Nieuw–Guinea is dinsdag getroffen door enorme golven. Sommige eilanden voor de kust van het land zouden volledig onder water staan.

Volgens ooggetuigen hielden de golven zes uur aan. Het is nog niet bekend of er slachtoffers zijn gevallen, meldden media uit het ten zuiden van Papoea-Nieuw-Guinea gelegen Australië.

Honderden huizen, hotels en scholen zijn ondergelopen. Meer dan 1500 mensen zijn ontheemd. Het zwaarst getroffen zijn de provincies Oost-Sepik en Nieuw-Ierland. Reddingswerkers zeggen nog geen goed beeld van de omvang van de schade te hebben, omdat sommige afgelegen gebieden nog niet zijn bereikt.

Eerder dinsdag was Papoea-Nieuw-Guinea getroffen door twee aardbevingen, elk met een kracht van iets meer dan 5 op de schaal van Richter. Bij de nabijgelegen Kermadec-eilanden was een aardbeving van 6,8 op de schaal van Richter. Of de golven zijn veroorzaakt door de bevingen is niet duidelijk.

In juli 1998 werd het noorden van Papoea-Nieuw-Guinea getroffen door een zware tsunami. Golven van meer dan 10 meter hoog zaaiden tot honderden meters landinwaarts dood en verderf. Meer dan 1600 mensen kwamen om.

Aardbeving schudt Zweden wakker

AMSTERDAM - Het zuiden van Zweden en delen van Denemarken en noord-Duitsland zijn vanmorgen wakker geworden met een aardbeving met een kracht van circa 4.8 op de schaal van Richter.

Volgens de seismologische instituten in Kopenhagen en Uppsala gaat het om de zwaartse aardschok in de regio in ruim honderd jaar. Om 6.20 uur schudde de aarde gedurende vijf seconden. Meubilair stond te wiebelen in de woonkamers, maar veel schade werd niet aangericht. Omdat aardbevingen in Scandinavië maar zelden voorkomen, dachten veel inwoners dat er een zwaar ongeval had plaatsgevonden.

Volgens Reynir Bödvarsson van het seismologisch instituut in Uppsala zijn naschokken niet uitgesloten

De watervallen zijn niet ver van de 2704 meter hoge vulkaan Poas, waar de beving aardverschuivingen ten gevolg had. De aardbeving had een kracht van 6,1 op de schaal van Richter.

Het epicentrum lag op ongeveer 30 kilometer ten noordwesten van de hoofdstad San José.

quote:

In the early morning hours of January 4, 2009, a pair of powerful earthquakes rattled Papua, Indonesia. The first earthquake, a magnitude 7.6 event, hit at 4:43 a.m., local time. The second, a 7.4 magnitude quake, followed at 7:33 a.m. The earthquakes damaged more than 800 buildings in Manokwari, the city nearest their epicenters, said the United Nations Office for the Coordination of Humanitarian Affairs on January 5. Five people died and approximately 250 were injured during the quakes, reported the UN.
The locations of the two earthquakes and the cluster of smaller associated quakes are illustrated in this image, which shows the topography of the island and the nearby seafloor. The region is geologically complex, says the U.S. Geological Survey (USGS), and that complexity is reflected in the image. On a large scale, the slab of Earth’s crust that contains the Pacific Ocean is moving southwest into the plate that carries Australia and Papua at a rate of about 112 millimeters per year, says the USGS. The Pacific plate slips under the Australia plate, creating a series of deep trenches on the sea floor where the plates meet.
The January 4 earthquakes, said the USGS, occurred in the region where the Pacific plate sinks below the Australia plate—a subduction zone. The subduction zone in this region is defined by the deep New Guinea trench north of Papua. The trench is the line of dark blue north of the earthquakes’ epicenters, where the depth of the ocean plummets. Though the earthquakes did not occur on the trench fault, they were likely associated with the large-scale motion of the Pacific plate sinking beneath the Australia plate, said the USGS.
More of the geologic complexity of the region is illustrated by the transform fault immediately south of the earthquake zone. A transform fault is a fracture in the Earth’s surface that forms along the edge of two plates moving horizontally past one another. The San Andres fault in California is probably the most famous transform fault. Papua’s transform fault is visible in the topography of the island. Since one side of the fault is higher than the other, a ridge line defines the fault.
If the Pacific plate is moving under the Australia plate, why is there a transform fault? In reality, the boundary between the two plates consists of a number of smaller plates that accommodate the motion of the larger plates. The smaller plates move more or less in concert with the larger plates, but create a messy mishmash of geologic structures associated with a variety of tectonic motions. The Papua region is a jigsaw of underwater trenches, ridges, and fault lines.

6.1 quake in Costa Rica on january 8th
A strong magnitude 6.1 earthquake caused at least 20 deaths in Costa Rica on January 8, 2009, said the U.S. Geological Survey (USGS). The earthquake was centered 30 kilometers north of San Jose (the country’s capital) and just 4.5 kilometers (2.8 miles) below the surface, a depth shallow enough to ensure strong shaking at the surface. The quake damaged buildings and sent earth tumbling in the mountainous Central American country. Landslides caused the majority of the deaths, said the USGS.
Costa Rica is prone to geologic hazards. As this image shows, active volcanoes dot the small country, and faults, both active and ancient, weave through the country. The January 8 earthquake was centered near two very active volcanoes, Poás and Irazú. Several faults also line the land near the epicenter. The darker colored faults have caused earthquakes during the historic record. The lighter colored faults have not been recently active. Further evidence of geologic activity lies in the high mountain range, the Cordillera de Talamanca, that runs parallel to the coast.
All of this geologic activity, the January 8 earthquake included, can be attributed to plate tectonics. The Cocos plate, a small portion of Earth’s surface beneath part of the eastern Pacific Ocean, is slipping beneath the portion of Earth’s surface that includes Costa Rica, the Caribbean plate. As the Cocas plate moves under the Caribbean plate at a rate of about 75 millimeters per year, it exerts pressure on the Caribbean plate. That pressure formed the mountains and the volcanoes. To ease the pressure, the earth near the edge of the plate shifts from time to time along weak points or faults. The January 8 earthquake did not occur along any known fault, but was caused by the build up of pressure from the subduction of the Cocas plate under the Caribbean plate, said the USGS.

Arkansas can be struck by 7.0 quake
LITTLE ROCK, Ark. — A previously unknown fault in eastern Arkansas could trigger a magnitude 7 earthquake with an epicenter near a major natural gas pipeline, a scientist said Wednesday.

Haydar Al-Shukri, the director of the Arkansas Earthquake Center at the University of Arkansas at Little Rock, said the fault is separate from the New Madrid fault responsible for a series of quakes in 1811-12 that caused the Mississippi River to flow backward.

Acres of cotton fields cover the fault west of Marianna, about 100 miles east of Little Rock, but stretches of fine sand mixed with fertile soil gave away the fault's location, Al-Shukri said. Liquefied sand bubbled up through cracks in the earth, while ground radar and digs showed vents that let the sand reach the surface, he said.

The fault, likely created in the last 5,000 years, sparked at least one magnitude 7 earthquake in its history. Such temblors cause massive destruction in their wake.

"This is a very, very dangerous (area) at risk of earthquake," Al-Shukri said. "When you talk about (magnitude) 7 and plus, this is going to be a major disaster."

Al-Shukri did not identify a time frame for the potential earthquake.

Such a quake would affect Little Rock and neighboring states such as Tennessee and Mississippi, Al-Shukri said.

The researcher has said a gas pipeline crossed the newly discovered fault. He declined to name the company that owned the pipeline. Al-Shukri had said in a speech at the University of Arkansas' Clinton School of Public Service that the company was building a large line through the area, mirroring the old one's path.

A map made by the Arkansas Public Service Commission shows an Arkla Energy Resources pipe in the area. A spokeswoman for CenterPoint Energy Inc., which owns Arkla, said Wednesday that the company worked closely with public officials to prepare response plans for earthquakes and other natural disasters.

Pipes are "all over the place," spokeswoman Rebecca Virden said. "We, CenterPoint Energy, or someone else has a pipeline everywhere."

Carl Weimer, executive director of the Pipeline Safety Trust in Bellingham, Wash., said companies with lines running through earthquake-prone Southern California have extra safety features including "more valves and different types of valves in case something happens and the pipeline can be shut off quicker."

Clint Stephens, the chief of pipeline safety at the commission, said the federal government would oversee any interstate lines. The U.S. Department of Transportation's Office of Pipeline Safety did not immediately respond to a request for comment.

Hundreds of earthquakes occur each year, including several in Arkansas. Most Arkansas earthquakes occur in the state's northeast corner in the New Madrid Seismic Zone, but Al-Shukri said the Marianna fault was not connected because it was too far from the temblors caused by that zone.

During the winter of 1811 and 1812, a series of three earthquakes with magnitudes of around 8 struck the zone and much smaller temblors continue to hit today.

Quake 'shakes Melbourne'

BREAKING NEWS: RESIDENTS across Melbourne have reported feeling the earth tremble as a quake appears to shakes the city.

Melburnians contacted the Herald Sun to report feeling the trembler from Carlton to Frankston.

The intesity of the tremor is not yet known.

MORE TO COME

Aardbeving treft Melbourne

De verwoestende bosbranden in het zuidoosten van Australië zijn nog maar nauwelijks onder controle, maar Moeder Natuur heeft opnieuw toegeslagen in het gebied. De miljoenenstad Melbourne werd vrijdag getroffen door een aardbeving, meldden Australische media.

De beving was niet al te groot, ongeveer 4,5 op de schaal van Richter, en richtte nauwelijks schade aan.

Toch kwam het hard aan in het rampgebied. De inwoners van de staat Victoria zijn na wekenlange bosbranden nog altijd aan het eind van hun Latijn. ,,We zitten zo dicht bij de vuurzee en we zijn de laatste twee drie, weken op onze hoede geweest. Onze enige gedachte was: mijn God, wat nu?'', zei een bewoonster tegen de zender ABC.

En de problemen in Australië zijn nog niet over. De staat Queensland, die vorige maand al werd getroffen door een overstroming, zet zich nu schrap voor de cycloon Hamish. De tropische storm komt vermoedelijk zondag aan land. De autoriteiten in de staat bereiden zich voor op een nieuwe watersnood.

More quakes will strike Victoria?
Seismologists say it is impossible to know whether further earthquakes will strike in Victoria, following the region's second quake in 11 days this afternoon.

A tremor that measured 4.6 on the Richter scale struck near Korumburra in Gippsland, 100 kilometres east of Melbourne, shortly after 4:00pm AEDT.

Residents reported their houses shaking for up to 10 seconds and experienced as many as three aftershocks.

Spiro Spiliopolous from Geoscience Australia says he cannot say when further quakes might occur.

"The answer is that we don't know. It's not possible to predict when earthquakes will occur," he said.

"It's unusual to see two earthquakes the same size occur in the same location, although it's not rare, not unheard of."

Seismologist John Schnieder of Geoscience Australia says the latest earthquake was probably in response to the last one.

"This earthquake undoubtedly occurred at least partially in response to the other one," he said.

"It would've occurred on the same fault and fracturing just a slightly different piece of turf."

There have been no reports of injuries but the State Emergency Service says anyone who has experienced damage should turn their power, water and gas off.

Many residents are saying this tremor was much stronger than the last one.

Peter Sutton of Warragul says he could feel his whole house moving.

"Sitting in the chair about to put the TV on; there was a giant crack and everything began to shake for about five or six seconds," he said.

"It felt like the whole house was shaking the whole house was moving from side to side."

ABC Online contributor Bruce says the quake was felt in Abbotsford in Melbourne's north-east.

"At first I heard the roof rattle and thought it was the cat jumping about," he said.

"Then the floor and walls started to shake for about seven seconds.

"Didn't feel the first one but definitely felt it today."

ABC Online contributor Helen S from Neerim North also felt the tremor.

"I heard the rumble, just before I felt two distinct jolts, like something hitting my cottage," she said.

"My roof made a horrible noise so I moved to the doorway.

"As I held the frame, I could feel the shudder through the post.

"The rumble continued and my crockery, an ornament with beads on it and a couple of other things, tinkled and made noises for about eight to 10 seconds."

CNN) -- A tsunami warning was issued and then canceled Friday shortly after a major earthquake struck early Friday off the coast of Tonga.

The earthquake "generated a small tsunami," but there is "no evidence of destructive waves," said Stewart Weinstein, assistant director of the Pacific Tsunami Warning Center in Hawaii.

Robert Cessaro, a geophysicist with the center, said: "There's a tsunami in the water, but it's not gonna do much."

On the largest island in the Tonga chain, Tongatapu, in the capital city of Nukualofa, a clerk at the International Dateline Hotel said the earthquake was felt but caused no damage.

At the Fafa Island Resort, off Nukualofa, Joseph Sanladerer told CNN that the earthquake woke up guests and shook wine glasses from racks, but caused no significant damage.

The tsunami center issued the regional tsunami warning for parts of the Pacific near the quake's epicenter, about 213 kilometers (132 miles) south-southeast of Nuku'alofa, Tonga. The quake struck at 6:17 a.m. local time (6:17 p.m. GMT).

At a depth of just 6.2 miles (10 km), it is considered a shallow earthquake. Typically, the shallower the quake, the more destructive potential it carries. But that is not always the case.

The USGS recorded the quake as 7.9 magnitude; the Pacific Tsunami Warning Center said it was 7.7. There were no immediate reports of damage or death.

The earthquake struck a few hours after a volcano erupted off Tongatapu, Tonga, about 200 km away.

Doden bij aardbeving Italië

Een krachtige aardbeving vanochtend in het midden van Italië heeft aan zeker twee personen het leven gekost. Talrijke mensen raakten gewond, meldde de Italiaanse zender Sky TG24.

Het epicentrum lag in de regio Abruzzen ten noorden van de provinciale hoofdstad L'Aquila. De beving was voelbaar in de Italiaanse hoofdstad Rome, die bijna 100 kilometer van L'Aquila ligt. Meldingen over de kracht lopen uiteen van 5,8 tot 6,7 op de schaal van Richter. Het Amerikaanse USGS houdt het op 6.3.

In L'Aquila renden mensen in paniek de straat op. Meerdere gebouwen in het historisch centrum stortten in. Reddingswerkers zochten onder het puin naar eventuele slachtoffers. Ook elders in de Abruzzen zouden huizen zijn beschadigd. Een deel van de autosnelweg naar Rome moest worden afgesloten.

Gisterenavond had zich in de streek rond het ruim tweehonderd kilometer noordelijker gelegen Ravenna een aardbeving voorgedaan met een kracht van 4,6 op de schaal van Richter. De schok werd tot in L'Aquila gevoeld.
