GEO330 at Southern New Hampshire University is a 3-credit undergraduate geohazards course. The catalog says it explores disasters due to natural phenomena including climate change, hurricanes, tornadoes, earthquakes, tsunami, volcanic eruptions, asteroid or comet impacts and mass extinctions.
Each type of event is considered by origin, evolution, warning potential, environmental impacts and possible mitigation, along with key historical cases. The difficulty is applying one framework to very different hazards.

Key Concepts Explained
A Common Framework
The catalog's own structure gives you a template for any hazard: origin, evolution, warning potential, impacts and mitigation. Use it for every case study so your answers stay organized.
Example: For a tsunami: origin (a large undersea earthquake displaces water), evolution (waves cross the ocean and grow in height near shore), warning potential (hours for distant coasts, minutes near the source), impacts (flooding, erosion, loss of life), mitigation (detection buoys, warning systems, evacuation routes, land use rules).
Hazard, Exposure and Risk
A hazard is the natural event. Risk combines the hazard with exposure and vulnerability. The same earthquake causes very different harm depending on building standards and preparedness.
Warning Versus Prediction
Some hazards allow warning (hurricane tracks), others very little (earthquakes). Distinguish forecasting a likelihood from predicting a specific event.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Hazard case study | Applying the framework to a real event | Use the five headings and cite the event's date and sources |
| Comparison of two hazards | Analysis | Compare warning time and mitigation options |
| Mitigation proposal | Evaluating solutions | Weigh cost, impact and limits |
| Discussion posts | Concise reasoning | One claim, one example, one source |
A Hazard Comparison Grid
One page that compares the hazards side by side is the best revision tool for this course. Fill the cells with your own notes and examples from your readings; the prompts below show what each column should answer.
| Hazard | Origin and warning | Mitigation |
|---|---|---|
| Hurricane | Warm ocean heat; days of warning through tracking | Forecasts, evacuation, building standards |
| Earthquake | Sudden fault slip; very limited warning | Building codes, preparedness |
| Volcanic eruption | Magma and gas reach the surface; often monitored, timing uncertain | Monitoring, exclusion zones |
| Tsunami | Large displacement of water; minutes to hours of warning | Warning systems, evacuation routes |
Using Historical Cases Well
The catalog stresses key historical cases, so every answer should be anchored in a documented event. Choose cases with good records and use them to show a point, not to tell the whole story.
Example: To argue that warning systems save lives, compare two coastal areas hit by a similar tsunami, one with a working alert system and one without. State dates, the warning time and the difference in outcomes, then explain what that suggests for mitigation elsewhere.
Always separate what the evidence shows from what you infer. That distinction is easy to mark and easy to reward.
Writing a Strong Case Study
Case studies earn marks when they are organized and evidence-based. A reliable structure is: introduce the event and why it matters, explain the origin, describe the impacts with figures, evaluate warning and mitigation, and end with lessons.
Example: For a volcanic eruption, the origin section explains the magma and gas conditions; the impacts section lists ash fall, evacuations and economic disruption; the mitigation section compares monitoring with exclusion zones; and the lessons section says what other regions can learn.
Where Students Get Stuck
- Descriptive answers. Explain mechanisms, not just damage.
- Mixing hazard and risk. Keep the natural event separate from human exposure.
- Weak case evidence. Use dated, credible sources.
- Prerequisite gaps. Revise Earth system and plate tectonics basics early.
Study Tips for GEO330
- Make a one-page grid: hazard by origin, warning, impact and mitigation.
- Keep two or three well-documented historical events per hazard.
- Revisit PHY205 notes on tectonics and volcanism.
- Use diagrams in your answers if permitted, and label them.
