Worked Solution & Example Answer:Examine the map opposite and answer each of the following questions - Junior Cycle Geography - Question 1 - 2015
Step 1
Explain what is meant by the term epicentre.
Answer
The epicentre is defined as the point on the Earth's surface directly above the origin of an earthquake, known as the focus. It is where the seismic waves first reach the surface, resulting in the strongest shaking and damage. The epicentre is typically described using geographical coordinates (latitude and longitude) on a map, helping to identify the location of the earthquake.
Step 2
Explain why the effects of the earthquake were greater in Christchurch than in Wellington.
Answer
The effects of the earthquake were greater in Christchurch due to its proximity to the epicentre, which was located near the city. Christchurch experienced more intense shaking and damage because it was closer to the energy release point of the earthquake. In contrast, Wellington, being further away from the epicentre, would have experienced weaker shaking. Additionally, Christchurch may have had specific geological factors such as soil type or building infrastructure that made it more vulnerable to earthquake damage.
Step 3
Describe two ways to reduce the impact of earthquakes.
Answer
-
Improving Building Codes: Implementing and enforcing stringent building codes ensures that structures can withstand seismic activity. This includes using materials and designs that enhance stability and reduce vulnerability during earthquakes.
-
Community Preparedness Programs: Educating the public about earthquake preparedness, including emergency response plans and safety protocols, can significantly reduce injuries and improve recovery efforts during and after an earthquake.
