- 1.8A: Prediction and forecasting. Role of scientists!
- Prediction- knowing when and where a natural hazard will strike on a spatial and temporal scale that can be acted on meaningfully
- Earthquakes cannot be predicted
- Research by scientists into predicting earthquakes focusses on warning signs e.g. movement of magma
- This is still in its infancy
- Research by scientists into predicting earthquakes focusses on warning signs e.g. movement of magma
- Tsunamis can be predicted, as we can detect the earthquake and predict during the lagtime as the tsunami forms and travels to land
- Important so we can evacuate coastal communities
- Japan 2011 tsunami was predicted
- There are 2 tsunami warning systems in the Pacific and Indian Ocean
- DART: deep-ocean assessment and reporting of tsunamis
- Works by using seabed sensors and surface buoys to monitor changes in sea level and pressure
- Then when tsunamis are detected the system sends information to warning stations
- Works by using seabed sensors and surface buoys to monitor changes in sea level and pressure
- Important so we can evacuate coastal communities
- Volanoes can be predicted, as they have warning signs before they erupt
- 1. They tilt the right as magma rises
- 2. Changes to shape of volcano, it will swell as magma rises
- 3. Small earthquakes b4 eruption on seismograms
- 1991 Mount Pinatubo was predicted by scientists
- Prediction allows for there to be better management of hazard impacts
- For predictions to be successful, they must be spatially and temporally accurate
- This means there is not a realistic prospect of being able to predict earthquakes in the near future
- Earthquakes cannot be predicted
- Forecasting- less precipe, provides a % chance of hazards occuring in a particular place
- Earthquakes can be forecasted
- This can be done via data and evidence gathered from global seismic monitoring and historical records
- It encourages governments to enforce better building regulations in areas of high stress
- Volanoes can be forecasted, as this is based on the statistical likelihood of an event happening in a location
- Earthquakes can be forecasted
- Prediction- knowing when and where a natural hazard will strike on a spatial and temporal scale that can be acted on meaningfully
- O.J on prediction and forecasting as an effective management technique of tectonic hazards
- Yes, volcanoes (Pinatubo) and tsunamis can be predicted (Japan), and this can encourage governments to prepare for an oncoming hazard, reducing its impact
- -We still cannot predict spatially and temporarlly e.g. Mount Ontake had 24/7 monitoring but wasn't predicted
- Until we have more accuracy, we should focus on predicting which societies are most at risk and help them to prep
