Quake rattles New Zealand's Christchurch

Dec 31 (Reuters) - An earthquake with a magnitude of 5.3 struck close to the New Zealand city of Christchurch on Saturday, the U.S. Geological Survey reported, but there were no immediate reports of damage or casualties.

The quake was measured only about 14 km (9 miles) northeast of the city. It was another in a series of quakes that have rattled the city since a major earthquake killed almost 200 people there 10 months ago.

There were no immediate reports of a tsunami warning.

A quake of a similar magnitude was felt in the area on Dec. 23, sending terrified residents from their houses but causing no casualties or major damage.

Christchurch, the largest city in New Zealand's South Island, is still recovering from a quake measuring 6.3 that killed 182 people in February and caused up to NZ$20 billion ($15.5 billion) in damage.

Large areas of Christchurch's business district are still off limits after the February quake, which toppled the city's famous cathedral, as well as shops, office buildings and homes.

New Zealand straddles the boundaries of the Indo-Australian and the Pacific tectonic plates and is hit by about 14,000 quakes every year, of which only a small number top a magnitude of 5.

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.
