Some vocabulary: 

• Disaster: A major hazard event that causes widespread disruption to a community or region that the affected community is unable to deal with adequately without outside help.

• Hazard: A threat (whether natural or human) that has the potential to cause loss of life, injury, property damage, socio-economic disruption or environmental degradation.

• Hazard event: The occurrence (realization) of a hazard, the effects of which change demographic, economic and/or environmental conditions.

• Risk: The probability of a hazard event causing harmful consequences (expected losses in terms of deaths, injuries, property damage, economy and environment).

• Vulnerability: The susceptibility of a community to a hazard or to the impacts of a hazard event.

Lesson 2: Characteristics of earthquakes 

• depth of focus (hypocenter)

• epicentre

• wave types (P, S, L, R) caused by varying types of plate margin movement and human triggers (dam building, resource extraction)

• associated secondary hazards (tsunami, landslides, liquefaction, transverse faults)

Ground shaking is the primary hazard. Everything else is a secondary hazard, including faults in the ground. 

Human triggers: Dam building and resource extraction
