Whay does the death toll vary from one earthquake to another?

What determines the destructive potential of an earthquake?

• The color of the earthquake

• The magnitude and depth of the earthquake

• The speed of the earthquake

• The name of the earthquake

Why do areas with higher population density experience a higher death toll during an earthquake?

• Because of the higher number of people at risk

• Because of the higher number of buildings

• Because earthquakes are attracted to these areas

• Because people are more scared

In the context of San Francisco, a city prone to earthquakes, how can local building codes and construction standards influence the impact of such natural disasters?

• They make earthquakes stronger

• They increase the cost of buildings only

• They have no effect

• They can reduce casualties by ensuring safer buildings

How does having an emergency response plan impact the outcome of an earthquake in a densely populated city?

• It makes the earthquake less severe

• It can help reduce casualties through quick response

• It increases the earthquake's magnitude

• It has no role

Why are wealthier regions often less vulnerable to earthquakes?

• Because they can afford better infrastructure

• Because they have fewer earthquakes

• Because earthquakes avoid wealthy areas

• Because they are located on better soil

How does the local geology of San Francisco affect the impact of an earthquake?

• It changes the color of the earthquake

• It has no effect

• Soft soil can amplify seismic waves, causing more damage

• It makes the earthquake sound louder

How can the time of day an earthquake occurs affect the number of casualties?

• Earthquakes at night have more colors

• People are more alert during the day

• Earthquakes are stronger at night

• Nighttime earthquakes might result in fewer casualties as people are indoors

What is the impact of being closer to the earthquake's epicenter on a city?

• It makes no difference

• It results in weaker ground motions

• It changes the earthquake's direction

• It results in stronger ground motions and more severe damage to buildings and infrastructure

Why do shallow earthquakes often have a more significant impact on the surface?

• Because they are closer to the surface, leading to more damage

• Because they move slower

• Because they are deeper

• Because they are less intense

What can quick and well-coordinated emergency responses include?

• Ignoring the earthquake

• Making the earthquake go away

• Search and rescue operations and medical assistance

• Predicting the next earthquake
