Tectonics- EQ3 Flashcards
How successful is the management of tectonic hazards & disasters? (8 cards)
3 Tectonic Mega-Disasters
2004 Indian Ocean Tsunami
2010 Eyjafjallajökull
2011 Japanese Tsunami
6 Parts of a Hazard profile?
Magnitude
Speed of onset
Areal extent
Duration
Frequency
Spatial Predictability
Multiple hazard zones (E.g Philippines) feature:
Earthquakes
Floods
Volcanoes
Mudslides
Drought
Pyroclastic Flows
Landslides
4 Stages to hazard management cycle?
Response
Recovery
Mitigation
Preparedness
Mitigation vs Adaptation
Mitigation: Actions that a community can use to help reduce vulnerability before a tectonic hazard
Adaptation: Ways in which communities may be able to live with a tectonic hazard by adjusting to help communities reduce risk
3 Stages to PARKS model (Response & Recovery)?
Relief (Hours-Days)
Rehabilitation (Days-Weeks)
Reconstruction (Weeks-Years)
Prediction of tectonic events consists of 3 things:
EQ’s occur on plate boundaries
Spatial prediction only
Tsunamis at 6.0M or greater
4 Strategies to modify the event:
Modify the cause
Modify the event
Modify the loss
Modify the vulnerability
