Earthquake Preparedness and Tectonic Activity

The video explores the tectonic activity in New Zealand, focusing on the Wellington fault, Alpine Fault, and Marlborough fault system. It explains the collision of tectonic plates and the resulting earthquakes, highlighting the differences between the South and North Islands. The video also covers the volcanic zone's unique earthquake characteristics and emphasizes the importance of preparedness and safety measures in an earthquake-prone country.

What is the primary reason for the frequent earthquakes in New Zealand?

• Weather changes

• Human activities

• Tectonic plate collisions

• Volcanic eruptions

Which fault is primarily responsible for the tectonic activity in the South Island?

• Hope Fault

• Wellington Fault

• Alpine Fault

• Marlborough Fault

What type of movement is most common along the Alpine Fault?

• Sideways movement

• Downward movement

• No movement

• Circular movement

What happens to the Alpine Fault as it moves north?

• It disappears completely

• It becomes inactive

• It breaks into a series of faults

• It merges with the Wellington Fault

In the North Island, which plate is subducting beneath the other?

• Australian plate beneath the Pacific plate

• Antarctic plate beneath the Australian plate

• Pacific plate beneath the Australian plate

• Pacific plate beneath the Antarctic plate

What is a potential consequence of the subduction zone in the North Island?

• Complete absence of earthquakes

• Large earthquakes similar to those in Japan

• Frequent volcanic eruptions

• Formation of new islands

Which earthquake is an example of activity in the volcanic zone?

• Edgecumbe earthquake of 1987

• Napier earthquake of 1931

• Wellington earthquake

• Canterbury earthquake

What is the primary characteristic of earthquakes in the volcanic zone?

• They cause tsunamis

• They are unpredictable

• They are generally smaller

• They are very large

What should you do if an earthquake starts?

• Drop, cover, and hold

• Stay in bed

• Run outside immediately

• Call emergency services

Why is it important to be prepared for earthquakes in New Zealand?

• Because they only occur in cities

• Because they are predictable

• Because they can happen anytime

• Because they are rare
