Natural Factors
A focus at this location will be the least deadly.
What is deep underground?
More damage and casualties may occur when the epicenter is near densely populated areas.
What is population density?
A measure of the amount of energy released by an earthquake.
What is magnitude?
Ensure that new buildings are designed and constructed to be earthquake-resistant.
What is develop and enforce building codes?
This type of crust is thinner, younger, and denser.
What is oceanic crust?
A focus at this location will be more deadly.
What is shallow? (close to the surface)
Structures that are more vulnerable to damage or collapse during an earthquake because of low quality materials and design.
What is building construction?
An earthquake of lesser magnitude following a large earthquake.
What is an aftershock?
Identify older buildings that may be at risk during an earthquake and improve their structural integrity
What is retrofit older buildings?
This was formed due to a continental collision between the Indian Plate and the Eurasian Plate. Because both plates are composed of continental crust, neither plate could sink under the other.
What are the Himalayan mountains?
This natural factor impacts people because many may struggle to escape collapsing buildings, and emergency systems may not be as well prepared.
What is time of day?
Not having the resources and infrastructure necessary for effective earthquake preparedness and response
What is a lack of preparation?
An instrument for detecting and recording the intensity, direction, and duration of seismic activity
What is a seismometer?
Provide alerts to people in affected areas, giving them time to take action to protect themselves and their families.
What are early warning systems?
This is the name of the fault line in California formed by a conservative plate boundary.
What is the San Andreas Fault?
This natural factor is related to the amount of time the shaking lasts for.
What is duration?
Things that can prevent earthquake damage from lack of preparation. Name at least 2
What are early warning systems, emergency services, modern medical facilities and education?
Used to measure earthquake size, replacing the Richter scale for larger earthquakes. It's more accurate than the Richter scale for larger events because it's based on the total energy released by the earthquake, not just the amplitude of seismic waves.
What is the Moment Magnitude Scale?
Elderly, children, and people with disabilities have access to the resources and support they need to prepare for and recover from an earthquake.
What is support vulnerable populations?
This is made up of the crust and upper mantle.
What is the lithosphere?
These two types of ground movement fall under the category of Geology when discussing the natural factors impacting how deadly an Earthquake is. Name at least one of the two.
What are liquefaction and subsidence?
Densely populated areas tend to have the following things that are more susceptible to damage from an earthquake. Name at least 3.
Buildings, infrastructure, and critical facilities, such as hospitals and schools.
The name for the area of the planet where an earthquake's seismic waves do not reach.
What is the "shadow zone"?
Increase public knowledge about earthquakes and how to prepare for them.
What are education and awareness campaigns?
The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate. (not the plate boundary, the name of the process)
What is subduction?
