Earthquakes and Their Impacts

These flashcards cover key concepts related to earthquakes, their impacts, and strategies for mitigation as discussed in the lecture.

Focus

The point within the Earth where an earthquake originates.

Epicenter

The point on the Earth's surface directly above the focus, where shock waves are strongest.

Primary impacts

Immediate effects of an earthquake, such as building collapses and loss of life.

Secondary impacts

Delayed effects following an earthquake, including homelessness and disease outbreaks.

LEDCs

Less Economically Developed Countries, which often suffer more severe effects from earthquakes due to poor infrastructure.

Mitigation

Strategies aimed at reducing the impacts of earthquakes, such as building design and emergency planning.

Shock waves

Vibrations that travel through the Earth as a result of an earthquake.

Building codes

Regulations that dictate the design and construction of buildings to ensure they can withstand earthquakes.

Evacuation routes

Designated paths for people to leave an area safely during an emergency, such as an earthquake.

Waterborne diseases

Illnesses caused by contaminated water, which can become a problem after an earthquake due to damaged infrastructure.
