17 aardbevingen in 18 uur tijd voor Christchurch
De Nieuw-Zeelandse stad Christchurch is op 18 uur tijd 17 keer door elkaar geschud door aardbevingen. Er is voorlopig geen sprake van grote schade.

Christchurch, de grootste stad van het zuidereiland, wordt al sinds september 2010 geteisterd door aardbevingen. Bij de beving in februari vorig jaar vielen nog 181 doden.

Onder de bevingen van vandaag waren er twee sterker dan 5 op de schaal van Richter.

De stad vraagt in een mededeling aan de inwoners om "te zorgen voor vrienden, buren en familie in deze moeilijke tijden". Burgemeester Bob Parker verzekerde dat de stad er alles aan doet om de belangrijkste diensten operationeel te houden. (dpa/adha)

Update 05/01 15:22 UTC
- A very curious pattern in GPS deformation patterns (the data which are published are probably 2 days old). The deformation at HI02, HI03 and HI04 climbed strongly ! La Palma deformation stayed approx. the same, but Tenerife and La Gomera GPS data decreased the strongest since the beginning of El Hierro activity. The current earthquakes at Tenerife may have an origin in this strong deflation (tension). The smoking lava Yesterday and Today also. @ IGN to solve the clue here. Hopefully they will explain in their report later today.

There seems to be moving in the Border GPS station in the last two days, in every season reflects a movement that has similar characteristics and should be monitored to see if it continues the next day.

Comparing the data of IGN compared to other stations of Frontera, it's like Frontera station was moving to the east, as there is no relative motion with respect to NS Palma and a movement of approach compared to the Tenerife. HI02, HI03 and HI04 seem to have the same pattern of separation.

As for the vertical deformation .... will have to wait to see part of IGN happens, but if some do not move and goes to the East border, depart hence, it is conceivable that there should be an inflation (Enrique) .

4,5 quake rattles Christchurch
At 1:21 a.m. local time (7:21 a.m. Eastern), a 4.5-magnitude earthquake struck New Zealand, roughly 25 kilometers east of Cristchurch. It originated from approximately 6.2 miles below the surface.

The area is not a stranger to earthquakes, as they were hit by a 5.8-magnitude tremor just two days before Christmas. There were thousands of recorded aftershocks following a 7.0-magnitude quake that struck on Sept. 4, 2010. Amazingly, no deaths resulted from that earthquake.

There have been no reports of injuries or damage from this earthquake, but we will keep you updated as details roll in.

6.6 Quake strikes off the Santa Cruz Islands
LATA, SOLOMON ISLANDS (BNO NEWS) -- A strong earthquake struck off the Santa Cruz Islands in the Pacific Ocean on late Monday afternoon, seismologists said, but there were no immediate reports of damage or casualties.

The 6.6-magnitude earthquake at 3:07 p.m. local time (0407 GMT) was centered about 75 kilometers (46 miles) west-northwest of Lata, the provincial capital of Temotu Province on Nendo island, which is part of the Santa Cruz Islands in the Solomon Islands. It struck about 38.9 kilometers (24.2 miles) deep, making it a shallow earthquake, according to the United States Geological Survey (USGS).

The USGS estimated that approximately 14,000 people on islands in the region may have felt strong shaking, which would be unlikely to result in serious damage or casualties. Tens of thousands more may have felt weak to moderate shaking, but there were no initial reports of damage.

Both the Pacific Tsunami Warning Center (PTWC) and the Joint Australian Tsunami Warning Center (JATWC) said there was no threat of a tsunami. "No destructive widespread tsunami threat exists based on historical earthquake and tsunami data," PTWC said in a bulletin.

The Solomon Islands are on the so-called 'Pacific Ring of Fire', an arc of fault lines circling the Pacific Basin that is prone to frequent and large earthquakes. Volcanic eruptions also occur frequently in the region.

The Solomon Islands arc as a whole experiences a very high level of earthquake activity, and many tremors of magnitude 7 and larger have been recorded since the early decades of the twentieth century.

On April 2, 2007, a massive 8.1-magnitude earthquake struck close to the New Georgia Islands of the Solomon Islands. It unleashed a regional tsunami, killing 52 people and destroying more than 300 homes, schools and a hospital at Sasamunga. Two people were killed as a result of landslides, which were triggered by the earthquake

EVALUATION

A DESTRUCTIVE WIDESPREAD TSUNAMI THREAT DOES NOT EXIST BASED ON
HISTORICAL EARTHQUAKE AND TSUNAMI DATA.

HOWEVER - THERE IS A VERY SMALL POSSIBILITY OF A LOCAL TSUNAMI
THAT COULD AFFECT COASTS LOCATED USUALLY NO MORE THAN A HUNDRED
KILOMETERS FROM THE EARTHQUAKE EPICENTER. AUTHORITIES IN THE
REGION NEAR THE EPICENTER SHOULD BE MADE AWARE OF THIS
POSSIBILITY.

Series of quakes strike North Island
A flurry of small earthquakes has rattled the North Island this morning.

Two early-morning quakes rumbled under Taupo in the wee hours, both at relatively shallow depths.

The first, at 3.07am, measured magnitude 2.9 and hit at a depth of 5km, 10km west of Taupo.

The second, in the same place but at a depth of 2km and measuring 2.4, hit at 4.55am.

Both were felt by Taupo residents, Geonet reported.

Two slightly larger quakes hit Napier and Hastings later in the morning, with the largest measuring 4.3.

The quake was centred 30km southeast of Hastings at a depth of 30km, and hit at 8.49am.

Geonet reported the quake was felt as far south as Waipakurau.

A 3.3 quake was reported just two minutes earlier, at a depth of 20 km, 20km south of Hastings.

There were no reports of damage.

Christchurch rumbled by series of quakes
A 24-hour period without earthquakes ended for Christchurch residents with a 3.7, a 4.5 and then a 4.0-magnitude tremor this morning.

The 3.7-magnitude quake, which struck shortly before 3am, was centred 10 kilometres east of Christchurch at a depth of 10km.

The 4.5-magnitude quake struck at 6.46am, centred 20km east of Christchurch at a depth of 12km, while the 4.0-magnitude shake struck just after 8.30am, centred 20km west of Christchurch and 9km deep.

The continued shaking comes as the city's business leaders call for urgent decisions to be made on the siting of Christchurch's new convention centre and the future of AMI Stadium.

Canterbury Employers' Chamber of Commerce chief executive Peter Townsend said authorities could not afford to dally over positioning of infrastructure assets such as the convention centre because it was critical to determining where other developments would go.

"The centre's siting and AMI Stadium are key decisions required immediately," he said.

"They are critical to what will happen in a lot of the rest of the city."

Demolition of the city's quake-damaged convention centre started last week.

The city council plans to build a $200 million replacement but has yet to confirm where it will be built.

75% chance of a 7+ quake hitting Tokyo within 4 years
A big earthquake is much more likely to hit the Japanese capital, Tokyo, in the next few years than the government has predicted, researchers say.

The team, from the University of Tokyo, said there was a 75% probability that a magnitude 7 quake would strike the region in the next four years.

The government says the chances of such an event are 70% in the next 30 years.

The warning comes less than a year after a massive earthquake and tsunami devastated Japan's north-eastern coast.

The last time Tokyo was hit by a big earthquake was in 1923, when a 7.9 magnitude quake killed more than 100,000 people, many of them in fires.

Researchers at the University of Tokyo's earthquake research institute based their figures on data from the growing number of tremors in the capital since the 11 March 2011 quake.

They say that compared with normal years, there has been a five-fold increase in the number of quakes in the Tokyo metropolitan area since the March disaster.

They based their calculations on data from Japan's Meteorological Agency, They said their results show that seismic activity had increased in the area around the capital, which in turn leads to a higher probability of a major quake.

The researchers say that while it is "hard to predict" the casualty impact of a major quake on Tokyo, the government and individuals should be prepared for it.

Correspondents say that while the university calculations take account of greater seismic activity since March, government calculations may use different or less up-to-date data and different modelling techniques.

The 9.0 magnitude earthquake last year aksi crippled the cooling systems at the Fukushima nuclear power station, causing meltdowns in some of its reactors.

Japan is located on a tectonic crossroads dubbed the "Pacific Ring of Fire" which is why its is commonly regarded as one of the world's most quake-prone countries, with Tokyo located in one of the most dangerous areas.

Noord-italie opgeschrikt door aardbeving
Het noorden van Italië is vanmorgen opgeschrikt door een aardbeving. In Milaan liepen veel mensen ongerust de straat op. In gebouwen vielen allerlei voorwerpen, maar er zijn geen berichten over doden of gewonden. Dat hebben Italiaanse media gemeld.

De krachtigste aardbeving - 4,9 op de schaal van Richter - vond volgens het nationaal geofysisch instituut rond 9 uur plaats. Het epicentrum van die beving bevond zich nabij de stad Reggio Emilia, in de regio Emilia-Romagna. Ook in Milaan, de op een na grootste stad van het land, was de schok voelbaar. De aardschokken zijn gevoeld in de regio's Lombardije, Emilia-Romagna, Veneto en Piemonte.

Vannacht had zich al een aardbeving met een kracht van 4,2 op de schaal van Richter voorgedaan in de buurt van Verona, gevold door een naschok met een magnitude van 2,9.

Grote delen van Italië zijn seismisch actief gebied. Bij de aardbeving in L'Aquila in 2009 vielen meer dan 300 doden. In december 1908 vielen in Sicilië en Calabrië ongeveer 100.000 doden door verwoestende aardschokken. (belga/adha/sg)
