What are earthquake hazards?
Earthquake hazards include ground shaking, ground rupture, landslides, liquefaction, tsunamis, and aftershocks. These can result in damage to buildings, infrastructure, and loss of life. It is important to be aware of and prepared for these hazards in earthquake-prone areas.
What is the shaking that results from the movement of rock beneath Earths surface?
The shaking that results from the movement of rock beneath Earth's surface is called an earthquake. This shaking is caused by the release of energy stored in the Earth's crust due to movements along faults. Earthquakes can vary in intensity and can cause significant damage to buildings and infrastructure.
What is the type of earthquake that does damage to roads and buildings?
The type of earthquake that causes damage to roads and buildings is typically a strong or major earthquake. These earthquakes have higher magnitudes and release more energy, leading to more intense shaking that can result in structural damage to infrastructure like roads and buildings.
What is earthquake hazard?
Earthquake hazard refers to the potential for ground shaking, surface rupture, ground displacement, and other associated effects that can result from an earthquake event. It represents the probability of an earthquake occurring in a specific area and the level of damage it can cause to people, buildings, infrastructure, and the environment. Understanding earthquake hazard is crucial for developing effective mitigation measures to reduce the risk and impact of earthquakes.
What are the characteristics and effects of love waves in an earthquake event?
Love waves are a type of surface seismic wave that move in a horizontal, side-to-side motion. They are the second fastest seismic waves and can cause significant shaking and damage during an earthquake event. Love waves have a higher frequency and amplitude compared to other seismic waves, which can lead to stronger ground shaking and potential destruction of buildings and infrastructure.

What does the intensity of an earthquake measure?
The amplitude and acceleration of ground shaking at a particular place as well as the resultant damage to buildings and other infrastructure. Unlike earthquake magnitude, the intensity can vary from place to place.

The type of earthquake that causes damage to roads and buildings is typically a strong or major earthquake. These earthquakes have higher magnitudes and release more energy, leading to more intense shaking that can result in structural damage to infrastructure like roads and buildings.
How many land destroyed in christchurch earthquake?
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.
Why is there noise with an earthquake?
The movment does cause the rattle of buildings shaking as well.

What is it about the earthquake that damages the buildings?
Tectonic plates move below the ground, shaking and damaging buildings foundations.
Describe the damage an earthquake does?
Earthquakes can cause damage by shaking the ground, leading to buildings collapsing, landslides, and tsunamis in coastal areas. The intensity of the damage depends on factors like the magnitude of the quake, depth of the earthquake, distance from the epicenter, and the quality of buildings and infrastructure in the affected area.
How does an intensity 5 earthquake differ from an intensity 7 earthquake?
An intensity 5 earthquake is considered moderate and can cause shaking that is felt by many people, potentially causing slight damage to buildings. In comparison, an intensity 7 earthquake is considered major and can cause widespread damage, including collapse of buildings and infrastructure. The shaking intensity and potential impact on structures and people are significantly higher in an intensity 7 earthquake compared to intensity 5.
What does an earthquake do to saturated soil?
An earthquake can cause saturated soil to liquefy, lose strength, and flow like a liquid instead of a solid. This can lead to ground shaking more intensely, causing buildings and structures to sink or tilt. It can also trigger landslides and create hazardous conditions for buildings and infrastructure.
