Tectonic Hazards - Key Words

A natural hazard caused by movement of tectonic plates (including volcanoes and earthquakes).
Tectonic Hazard
1 of 17
Actions taken before a hazard strikes to reduce its impact, such as educating people or improving building design.
Protection
2 of 17
Actions taken to enable communities to respond to and recover from natural disasters, through measures such as warning systems and evacuation plans
Planning
3 of 17
Tectonic plate margin where two plates are converging/coming together (subduction of the oceanic plate). Associated with violent earthquakes and explosive volcanoes
Destructive Plate Margin
4 of 17
Attempts to forecast when and where a natural hazard may occur based on current knowledge (can be done to some extent for volcanic eruptions and tropical storms, not so reliable for earthquakes)
Prediction
5 of 17
The reaction of people as the disaster happens and in the immediate aftermath
Immediate Response
6 of 17
The initial impact of a natural event on people and poverty caused directly by it. For example, the buildings collapsing following an earthquake
Primary Effects
7 of 17
Recording physical changes, such as earthquake tremors around a volcano, to help forecast when and where a natural hazard might strike
Monitoring
8 of 17
An opening in the Earth's crust from which lava, ash and gases erupt
Volcano
9 of 17
Tectonic plate margin where rising magma adds new material to plates that are diverging/moving apart
Constructive Plate Margin
10 of 17
The margin or boundary between two tectonic plates
Plate Margin
11 of 17
Later reactions that occur in the weeks, months and years after the event
Long-Term Responses
12 of 17
A rigid segment of the Earth's crust which can 'float' across the heavier, semi-molten rock below. Continental plates are less dense but thicker than oceanic plates
Techtonic Plate
13 of 17
Techtonic plate margin where two plates slide past each other
Conservative Plated Margin
14 of 17
A natural event (e.g. earthquake, volcanic eruption, tropical storm etc.) that threatens people or has the potential to cause damage, destruction and death
Natural Hazard
15 of 17
A sudden or violent movement within the Earth's crust followed by a series of shocks
Earthquake
16 of 17
The after-effects that occur as indirect impacts of a natural event (sometimes on a longer timescale). For example, fires due to ruptured gas mains resulting from the ground shaking
Secondary Effects
