- No tectonic hazards can be predicted
- Volcanoes show more signs of erupting and speed of onset is slower
- Earthquakes happen quickly and show few signs
- Tsunamis often happen after earthquakes so they can be easily predicted
- Scientists play a huge role in prediction and forecasting, they often warn people to evacuate
- Emergency planners are important in measuring impacts e.g Aid Workers to reduce deaths
- Scientists cannot predict time or place even to within years. They can use hazard risks maps to estimate probability or a place even being hit by an Earthquake e.g in the next 5 years
Tsunami
Predictions:
- Caused by Earthquakes so we cannot predict the start of them
- After an earthquake can track tsunami waves in the ocean (partial-perception)
- Ocean monitoring stations called floats record pressure and how it changes
- Computer models to create tsunami risk prediction maps
- Warning is sent to everyone e.g Automatic text messages sent to everyone in Japan
Volcano
Predictions:
- Easiest to predict
- However, we still cannot accurately predict them
- Show most signs of activity and they have a longer speed of onset
