What type of earthquake was the Christchurch 2011?

The hidden fault that caused the February 2011 Christchurch earthquake. In September 2010, Christchurch was shaken by the magnitude 7.1 Darfield earthquake, caused by movement along faults west of the city on the Canterbury Plains.

What type of earthquake was the Christchurch earthquake?

The earthquake was a “strike-slip event with oblique motion” which caused mostly horizontal movement with some vertical movement, with reverse thrust causing upwards vertical movement. The vertical acceleration was far greater than the horizontal acceleration.

What type of fault was the Christchurch earthquake 2011?

The earthquake’s epicentre was located some 25 miles (40 km) west of Christchurch near the town of Darfield, and the focus was located about 6 miles (10 km) beneath the surface. It was caused by right-lateral movement along a previously unknown regional strike-slip fault in the western section of the Canterbury Plains.

What type of plate boundary was the New Zealand 2011 earthquake?

A group of dextral strike-slip structures, known as the Marlborough Fault System, transfer displacement between the mainly transform and convergent type plate boundaries in a complex zone at the northern end of the South Island.

On the city experienced a series of strong aftershocks, including a magnitude 5.6 and a 6.3. A further series hit the region on . Both events caused further damage and disrupted the city’s recovery.

The biggest NZ earthquake – magnitude 8.2 Wairarapa earthquake in 1855. On an international scale, the 1855 earthquake is of major significance in terms of the area affected and the amount of fault movement.

Why didn’t a tsunami occur in the Christchurch earthquake 2011?

The September 2010, February 2011 and June 2011 earthquakes did not cause tsunamis because they happened on land and did not disrupt the sea floor.

Will tsunami hit New Zealand?

Has New Zealand been hit by tsunamis? New Zealand has experienced about 10 tsunamis higher than 5m since 1840. Some were caused by distant earthquakes, but most by seafloor quakes not far off the coast. A nearby coastal seafloor earthquake is the only warning people may get before a tsunami arrives.

How far inland can a tsunami travel NZ?

1.5km

Locally generated tsunamis
If you cannot go higher, go inland – at least 1.5km.

How long would it take a tsunami to travel across the Pacific Ocean?

How long does it take a tsunami to reach land? Once generated, a tsunami wave in the open ocean can travel with speeds greater than 800 kilometres an hour. These waves can travel across the Pacific Ocean in less than one day. Locally generated tsunamis can reach coastlines in just minutes.

How fast was the fastest tsunami?

Last September, an earthquake triggered a deadly tsunami in Indonesia. Scientists now have clocked the speed of rupture at a blistering 9,600 miles per hour.

How tall can tsunamis get?

Tsunamis may reach a maximum vertical height onshore above sea level, called a runup height, of 98 ft. (30 meters). A notable exception is the landslide-generated tsunami in Lituya Bay, Alaska in 1958, which produced a 1722 ft. wave (525 m).

How do you survive a tsunami if you are in the water?

Drop to your hands and knees. Cover your head and neck with your arms. Hold on to any sturdy furniture until the shaking stops. Crawl only if you can reach a better cover, but do not go through an area with more debris.

Can you surf on a tsunami?

Can a ship survive a tsunami?

Boats are safer from tsunami damage while in the deep ocean ( > 100 m) rather than moored in a harbor. But, do not risk your life and attempt to motor your boat into deep water if it is too close to wave arrival time. Anticipate slowdowns caused by traffic gridlock and hundreds of other boaters heading out to sea. 4.

Can a boat outrun a tsunami?

Can a speed boat outrun a tsunami? Yet a myth persists that a person could outrun a tsunami.
