Christchurch

The Christchurch earthquake severely damaged the Christchurch Cathedral in 2011, leading to its partial collapse. The structure has since been deemed unsafe and awaits a decision on its future, with ongoing discussions surrounding its restoration or potential demolition.

The 6.3-magnitude earthquake in Christchurch on Feb 22, 2011 was caused by the rupture of a previously unknown fault line located under the region, rather than the nearby major Alpine Fault. This fault line, called the Port Hills fault, produced intense ground shaking that led to significant damage in the city.

Christchurch, New Zealand has an average elevation of about 13 meters (43 feet) above sea level. However, specific areas of the city can range from sea level to higher elevations depending on their location.

Christchurch, New Zealand has experienced several significant earthquakes, with the most notable being the Canterbury Earthquake sequence in 2010 and 2011. These earthquakes caused widespread damage and loss of life in the region.

The Christchurch earthquakes started on September 4, 2010, with the last major event occurring on February 22, 2011. Aftershocks continued for several years, with the most significant one being the June 13, 2011 event. The overall seismic activity in Christchurch lasted for several years, impacting the region on various scales.

There have been thousands of aftershocks following the major earthquakes in Christchurch in 2010 and 2011. These aftershocks occur over a period of time as the Earth's crust adjusts to the initial seismic activity.

Christchurch is twinned with the following towns: Aalen in Germany, Lokeren in Belgium, Christchurch in Canada, and Christchurch in Australia.

The 2011 Christchurch earthquake in New Zealand destroyed around 6,000 homes and caused significant damage to various buildings and infrastructure. The exact amount of land destroyed is difficult to quantify, as it varied across different areas based on the intensity of the shaking and other factors.

The Christchurch earthquake in 2011 resulted in significant damage to buildings, infrastructure, and loss of life. It caused an estimated $40 billion in damages and affected thousands of residents in the region.

The Christchurch earthquake that occurred on February 22, 2011, involved the Pacific Plate and the Australian Plate along the boundary known as the Alpine Fault. The earthquake was a result of complex interactions between these two plates.

Yes, the Christchurch earthquake of 2011 resulted in the loss of 185 lives.

The Christchurch earthquake in 2011 caused significant damage to landmarks such as the Christchurch Cathedral, the iconic Christchurch Arts Centre, and the ChristChurch Anglican Cathedral. Many heritage buildings in the central business district were also destroyed or badly damaged.

Following the 6.3 magnitude earthquake in 2011, Christchurch experienced thousands of aftershocks. These aftershocks continued for several years, with some reports estimating over 10,000 aftershocks in total.

The reason that there have been so many aftershocks after the 2010 Christchurch earthquake is because bigger earthquakes have not only stronger aftershocks, but more of them.

Aftershocks happen because when an earthquake occurs, the earth's plates hardly ever settle into a stable position straight away. So, the newly moved rock has to be settle.

he Earth's crust, or lithosphere (hard outer surface) is made up of "tectonic plates", or large plates. There are about 7 major plates and many smaller plates, around 100 km thick, which sit upon a lower soft layer (the asthenosphere). The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.

This accumulation of stress causes the rocks that make up the crust to deform elastically. This is very similar to what happens when you squash or stretch a spring and causes a form of energy to be stored in the rocks of the crust - technically described as elastic potential energy.

When this stress gets too large, it exceeds the strength of the rocks in the crust and causes a brittle failure. Brittle failures are failures where fractures form through the material. As these have been happening for a long time, the earth's lithosphere is already fractured. These fractures are known as faults and as these represent zones of weakness within the lithosphere, it is along faults where the majority of earthquake occur when they slip suddenly.

This sudden brittle failure causes all of the elastic potential energy to be released at one time in the form of seismic waves, just as if a spring or elastic band that was being stretched suddenly snapped.

These seismic waves cause the tremors that people feel on the surface and which can cause damage to buildings and other structures.

Christchurch lies on the Pacific Plate. The boundary of the Pacific Plate and the Australian Plate is near the South Island of New Zealand, where Christchurch is located. This region is seismically active due to the interaction between these two plates.

The most destructive earthquake in Christchurch occurred on February 22, 2011, with a magnitude of 6.3. It resulted in significant damage to the city and tragically caused many casualties.

More than 100 and they're still coming. mate theres more than 600 theres been about 2000 now. Ok Really theres been 4153, you can look on the Christchurch Quake Map provided on the link below

UPDATE: As from today (6 June 2012) there have been almost 11,000 since 4th september 2010, of a magnitude 2 or greater. (Actually, just had about 5 minutes ago!)

no one.

But some people had cuts and bruises.

Two people had serious injuries.

One person got hit by a falling brick chimney. The other got seriously cut by a whole lot of sharp, falling glass that was flying in the earthquake.
