Study Notes
Earthquakes and Tsunamis
- The collapse of buildings caused by earthquake vibrating water-saturated fill or unconsolidated soil is a secondary effect of an earthquake known as liquefaction.
- Landslides or explosions under the ocean can cause tsunamis.
- Intersecting lines on a map can help locate a specific place.
Tsunami Characteristics
- A tsunami sounds like a train or a loud roar.
- Tsunamis can cause rapid changes in water level and unpredictable dangerous currents in harbors and ports.
- Tsunamis generated in distant locations may give people enough time to move to higher ground.
- Local tsunamis could strike some areas before a tsunami warning could be announced, leaving only a few minutes to move to higher ground.
Tsunami Safety
- If a tsunami warning is issued while at school, follow the advice of teachers and school personnel before making any move.
- If retreating ocean water is observed, watch for a sudden change in wave level.
Earthquake Hazard Reduction
- Building design and construction professionals use Seismic Design Categories (SDCs) specified in building codes to determine the level of seismic resistance required for new buildings.
- SDCs help reduce the risk of earthquakes.
Earthquake Preparedness
- To prepare for an earthquake, choose a safe place in every room of your house, such as sturdy tables or desks.
- During an earthquake, stay away from gas, electrical lines, and fuel lines, and avoid overturning stoves, which can lead to fires.
- When inside a building during an earthquake, do not call friends and relatives; instead, drop, cover, and hold on.
Earthquake Maps
- In an earthquake map, the strongest shaking is often represented by the color red.
Earthquake Risks
- Accurate data gathering, recording, and interpretation of ground shaking data are essential components of earthquake risk reduction.
- Careful analysis and interpretation of ground shaking data are necessary to reduce earthquake risks.
Community Resilience
- A community that has no earthquake preparedness measures in place will be most affected by an earthquake.
