Concept 1
An event (naturally occurring) which has the potential to cause loss of life or property.
A hazard
The boundary where two plates slide past one another.
What is a Transform boundary ?
Where plates move away from one another often causing trenches.
What are divergent boundaries ?
It is NOT a Tsunami but it waves generated within an enclosed body of water by earthquake tremors
What is seiche?
The probable severity that a natural event can cause to life and livelihood.
What is risk?
Earthquakes, volcanoes and tsunami’s are caused by what geophysical process?
What is geological?
The most powerful type of volcanic eruptions.
What is plinian?
The after-effects that occur as indirect impacts of a natural event
What are Secondary Hazards?
They are the slowest but most damaging type of earthquake waves.
What are surface waves?
The likelihood of an area being affected by a natural event.
What is vulnerability?
Cyclones, storms and tornados are all examples of what type of geophysical process?
What is atmospheric?
The initial impact of a natural event on people and property, caused directly by it.
What is Primary Hazard?
The point at the Earth’s surface directly above the focus.
What is the epicenter?
An overflow or temporary accumulation of water that covers an area that is usually dry.
What is a flood?
This crust is mainly made of Basalt.
What is the oceanic crust?
Tectonic plate margin where two plates are moving towards each other. It can be associated with violent earthquakes and explosive volcanoes.
What is Convergent boundary?
Action taken to reduce or eliminate the long-term risk to human life and property from natural hazards.
What is mitigation?
Energy released by an earthquake.
What is seismic waves?
A type of flooding caused when lakes and rivers overflow its banks.
What is Riverine Flooding?
75% of volcanic eruptions occur along this area.
What is the Ring of Fire ?
Actions taken to enable communities to respond to, and recover from, natural disasters, through mitigation and measures of preparedness.
What is Disaster Management Cycle?
The process of a more dense lithospheric plate going under a less dense plate.
What is Subduction ?
Impact of a natural event that results in serious damage and many deaths.
What is a disaster?
A flood caused by heavy or excessive rainfall in a short period of time.
What is a Flash flood?
Batholiths, sills, dykes and laccoliths are this type of volcanic features
What is intrusive?
