Earthquake management Flashcards
1
Q
Prediction
A
- No reliable way
- Seismic records
- Randon gas emissions
- Groundwater
- Remote sensing
- Low-frequency electromagnetic activity
2
Q
Seismic records
A
- Studying patterns = help predict next event
- Seismometer - seismic shock
3
Q
Randon gas emissions
A
- Radon - inert gas = released from rocks - granite
- Faster released when fractured by deformation
4
Q
Groundwater
A
- Deformation = water level rise or fall
5
Q
Remote sensing
A
- Electromagnetic disturbances in atmosphere
6
Q
Low-frequency electromagnetic activity
A
- Detected from earthquake regions satellite = observations = strong correlations
- Low frequency and seismically most active zone
7
Q
Protection
A
- Earthquake buildings
- Raising public awareness - education
8
Q
Earthquake buildings
A
- Fire-resistant - computer-controlled weights on rood and steel frames that can sway.
- Land use planning - most at-risk areas.
9
Q
Preparation
A
- Evacuation routes
- Household - emergency supplies
- Insurance
