Christchurch Earthquake

The Christchurch earthquake, lasting only 12 seconds, caused significant damage and loss of life. New Zealand, located on the Ring of Fire, experiences frequent seismic activity due to the interaction of the Pacific and Australian Plates. The 2011 Christchurch quake was an aftershock of the 2010 earthquake, with greater impact due to its proximity and shallowness. The slap down effect and liquefaction exacerbated the damage. Seismologists study these events to improve earthquake prediction.

What is the Ring of Fire known for?

• Being a volcanic region with no earthquakes

• Having 90% of the world's earthquakes

• Being a calm and stable tectonic area

• Having the least seismic activity on Earth

What caused the release of energy that triggered the Christchurch earthquake?

• The plates moving freely without resistance

• A sudden volcanic eruption

• A meteor impact near Christchurch

• The plates being stuck and then breaking free

Why was the February 2011 aftershock more impactful than the initial quake?

• It was shallower and closer to the city

• It was deeper and further from the city

• It occurred during a storm

• It had a larger magnitude

What is the slap down effect?

• A process that prevents liquefaction

• A phenomenon where the ground shakes less intensely

• A process where upper layers of earth move faster than lower layers

• A phenomenon where upper layers fall back and slap against lower layers

What is liquefaction and its consequence during an earthquake?

• A process that solidifies soil, reducing damage

• A process that turns solid soil to liquid mud, causing flooding

• A phenomenon that strengthens buildings

• A process that reduces seismic waves
