Natural Hazard Predictions

What is the best way to test building designs for earthquake resistance?

• Testing a single building design against multiple earthquake models.

• Testing multiple model buildings for one model earthquake to see how different designs perform.

• Using computer simulations to predict earthquake resistance.

• Conducting surveys of existing buildings after an earthquake.

What is the difference between a regular flood and a flash flood?

• A regular flood occurs suddenly and is often over in a short time, while a flash flood develops more slowly and can last for days.

• A regular flood develops more slowly and can last for days, while a flash flood occurs suddenly and is often over in a short time.

• A regular flood is caused by heavy rainfall, while a flash flood is caused by melting snow.

• A regular flood affects large areas, while a flash flood only affects small, localized areas.

What is the importance of building codes in earthquake-prone areas?

• They are only necessary for aesthetic purposes.

• They ensure that structures are designed to withstand seismic forces, reducing the risk of collapse during an earthquake.

• They are used to increase property taxes.

• They have no significant impact on safety during earthquakes.

How can buildings be designed to withstand earthquakes?

• By using lightweight materials that collapse easily

• By designing them to sway with the motion of an earthquake

• By making them as rigid as possible to resist movement

• By constructing them underground to avoid shaking

What can some earthquakes cause to roads?

• They can make roads smoother and safer.

• They can cause roads to buckle, leading to damage and making them unsafe for travel.

• They can create new roads in the affected areas.

• They can cause roads to become more durable and resistant.

What is the main cause of flash floods?

• Heavy rainfall that overwhelms drainage systems and natural water boundaries.

• Rapid snowmelt in mountainous regions.

• Drought conditions leading to sudden water release.

• Earthquakes causing landslides and water displacement.

What does urbanization mean?

• Urbanization is the process of building homes, parking lots, roads, and other infrastructure in urban areas, leading to the growth of cities.

• Urbanization refers to the migration of people from rural areas to urban areas without any change in infrastructure.

• Urbanization is the decline of cities and the movement of people to rural areas.

• Urbanization means the increase in agricultural activities in urban settings.

What is an example of a natural hazard?

• Tsunami

• Earthquake

• Volcanic eruption

• Meteor shower

What is the significance of studying past earthquakes?

• It helps scientists understand patterns and improve predictions for future seismic events.

• It allows scientists to predict the exact time of the next earthquake.

• It provides a way to prevent earthquakes from occurring.

• It helps in the construction of buildings that can withstand earthquakes.

What is a flash flood?

• A gradual increase in water levels over time.

• A sudden and intense flood caused by heavy rainfall or rapid snowmelt.

• A type of flood that occurs only in coastal areas.

• A flood that happens during the winter season.
