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)

125 injuries in Peru after quake
Update 21:15UTC: 125 people are reported to be injured (108 from the province of Ica (of which 73 from Dist. Ica, 6 from the Dist. Ocucaje, 10 from Dist. Parcona, 1 from Dist. Santiago, 6 from Dist. Tinguina, 10 from Dist. Guadalupe); 12 from the province of Pisco; 7 from the province of Chincha).

140 people are homeless of which 115 are in the Province of Ica and 25 from the Province of Pisco.

28 houses are uninhabitable (23 in Ica, 5 in Pisco) and 27 additional houses are damaged.

The 125 injured have been serviced and taken care of at local hospitals and health centers.

Earthquake-report.com commends INDECI for their speedy and also intensive and detailed work in collecting the damage statistics. A lot of much more developed nations could learn much from the Peruvian press reporting of disasters.

At least 13 killed in 6.8 quake
MANILA, Philippines (AP) -- A strong earthquake in the central Philippines killed at least 13 people Monday as it destroyed buildings and triggered landslides that buried dozens of houses, trapping residents. At least 29 people were missing.

The 6.8-magnitude quake, in a narrow strait just off Negros Island, caused a landslide in Guihulngan, a city of about 180,000 people in Negros Oriental province. As many as 30 houses were buried and at least 29 people were missing, Mayor Ernesto Reyes said.

"Their situation is bad because if you are covered by landslide for one hour, two hours, how can you breathe?" he said. "But we just hope for the best, that there are still survivors."

Rescuers were using picks and shovels to dig for survivors, he said.

Reyes said at least 10 people were confirmed dead in his town, including students at a college and an elementary school and others in a market that collapsed. About 100 were injured.

The quake, which hit at 11:49 a.m. (0349 GMT), triggered another landslide in the mountain village of Solongon in La Libertad town, also in Negros Oriental. An unknown number of people were trapped, said La Libertad police chief inspector Eric Arrol Besario.

"We're now getting shovels and chain saws to start a rescue because there were people trapped inside. Some of them were yelling for help earlier," Besario told The Associated Press by phone. Three key bridges in the town suffered cracks and were no longer passable, he said.

Philippine seismologists briefly issued a tsunami alert for the central islands. Five bamboo and wooden cottages were washed out from a beach resort in La Libertad by huge waves, but there were no reports of injuries, said police Superintendent Ernesto Tagle. Elsewhere along the coast, people rushed out of schools, malls and offices.

The epicenter was closest to Tayasan, a coastal town of about 32,000 people flanked by mountains in Negros Oriental province. Two died there, including a child when a concrete fence of a house collapsed, said Benito Ramos, head of the Office of Civil Defense.

Another child was killed in a church when a wall collapsed during a funeral in Negros Oriental's Jimalalud town, Mayor Reynaldo Tuanda said.

Tayasan police officer Alfred Vicente Silvosa told The AP by phone that aftershocks were preventing people from returning to their homes. Seismologists recorded nearly 45 aftershocks.

"We are outside, at the town plaza. We cannot inspect buildings yet because it's dangerous," Silvosa said. "I felt the building shaking, so I rushed out of the building. Our computers, shelves, plates, the cupboards, water dispenser all fell."

A three-story office building also collapsed in La Libertad, but occupants managed to run out.

Negros Oriental police chief Edward Carranza said the temblor damaged many houses in Guihulngan and he ordered his men to help displaced residents find shelter.

Officials in some areas suspended work and canceled classes. Power and telecommunications were knocked out in several places.

Carranza said police rushed out of his building when the quake struck. "All my personnel ran out fearing our building would collapse," he said.

"Now it's shaking again," he said as an aftershock hit. "My keychain is dancing."

The U.S. Geological Survey said the quake was centered 44 miles (72 kilometers) north of Dumaguete city on Negros and hit at a depth of 29 miles (46 kilometers). The area is about 400 miles (650 kilometers) southeast of the capital, Manila.

The Philippines is located in the Pacific "Ring of Fire" where earthquakes and volcanic activity are common. A 7.7-magnitude quake killed nearly 2,000 people in Luzon in 1990.
