Study Notes
- Earthquakes typically occur near tectonic plate boundaries or fault lines
- Predicting the exact timing of an earthquake is impossible
- Estimating potential future earthquakes is possible through understanding earthquake causes and regional history
Seismic Waves
-
Surface waves are the slowest type
-
Surface waves cause the most damage to buildings
-
Primary waves are the fastest seismic waves
-
Secondary waves cause rock particles to vibrate perpendicularly to the direction waves travel
-
Magnitude is a numerical system measuring energy or magnitude of the largest seismic waves
-
Liquefaction refers to the shaking from earthquakes turning wet soil into a liquid, leading to building collapse
-
Landslide refers to a rapid downhill movement of soil, rocks, and boulders during an earthquake
-
A tsunami is a large ocean wave caused by vertical motion of the seafloor, often from underwater earthquakes
Volcanoes
- Volcanoes are associated with plate boundaries and hot spots
- Volcanoes at plate boundaries form the Ring of Fire and the Mid-Atlantic Ridge
- Hot spot volcanoes are not associated with plate boundaries
- Volcanic gases, like sulfur dioxide, can irritate skin and eyes
