Study Notes
Natural Hazards and Disasters - Introduction Part 2
- A smart hazard approach is needed, considering economic globalization, multi-national information, and the negative impact of humans on the global environment. Local hazards like Calgary floods and Vancouver earthquakes necessitate a balanced, multifaceted approach to studying them. The 2011 Japanese earthquake illustrates the global reach of these events, causing widespread effects in North America.
- The November 2021 rain in Southern BC highlights disruptions to transport, extending beyond local areas and compounding existing issues like COVID supply chain problems, causing delays and extra costs.
Conceptual Framework for Decision-Making
- Hazard prediction through scientific analysis: Monitoring and recording events and processes enables predictions, forecasting future activity based on past patterns, magnitudes, and frequencies.
- Risk analysis: This important tool quantifies hazards to estimate probabilities and consequences.
- Linkages between natural hazards: One hazard can trigger another (e.g., an earthquake triggering a tsunami or heavy rain causing a landslide). These interdependencies must be considered in decision-making.
- Increasing damage from hazards: Hazards are becoming increasingly catastrophic as populations and investment grow, exacerbated by climate change and human activity, which increases both the magnitude and frequency of events. Minimizing damage requires integrated approaches using varied disciplines and perspectives.
Limitations of the Framework
- Despite a comprehensive system, there will always be situations that are difficult to record, analyze, or predict with certainty.
- Factors such as remote locations, fast-moving events, large forces, and a limited understanding of processes contribute to these limitations.
Why Use a Systems Approach?
- A systems approach helps organize analyses, crucial since natural hazards are processes driven by energy.
- Organizing analysis by energy sources and amounts is useful
Energy Sources driving hazards
- Earth's internal heat: Three mechanisms (atomic collisions, compression, and radioactivity) heat the Earth's interior, leading to mantle convection and plate tectonics. This results in earthquakes and volcanoes.
- Energy from the sun: Solar heating drives atmospheric and ocean circulation, producing weather patterns, leading to violent storms (hurricanes, tornados), droughts, floods, soil erosion, and coastal erosion.
- Gravitational attraction: Earth's gravity causes mass-wasting (landslides, mudslides, avalanches), and pulls in space objects (meteoroid/asteroid impacts)
Terminology
- Cause vs Trigger: A cause is the long-term buildup of conditions creating a hazard, while a trigger is the short-term event initiating the hazard's action. Often these terms are used interchangeably in common parlance (e.g., landslides, avalanches, and slipping on ice).
- Correlation vs Causation: Correlation describes how much two variables move together, while causation means a direct relationship where a change in one variable directly creates a change in another. Correlation does not necessarily signify causation.
- Natural vs Anthropogenic Hazards: Natural events or actions have no direct human involvement and are the result of natural processes, whereas anthropogenic factors have direct human actions or consequences. Sometimes natural and human influences are intertwined. (e.g., climate change, and the addition of CO2 changing the atmosphere to enhance hazards).
- Hazard vs Risk: Hazard is the potential for harm, while risk is the likelihood that harm occurs (the probability is factored in).
- Risk vs Uncertainty: Risk has known outcomes and likelihoods, while uncertainty implies unknowns about outcomes or probabilities.
- Risk vs Impact: Risk is the chance of the event occurring, Impact is the effect of that event if it occurs
- Risk vs Vulnerability: Risk is unrelated to vulnerability, which is a weakness in the system, meaning no context to the impact. Vulnerability doesn't directly relate to natural risks but usually relates to an impact.
- Disaster vs Catastrophe: Both result in serious injuries, death, and property damage over a specific geographic area over a short period. Catastrophes are larger, more widespread events with more severe consequences than a typical disaster
Magnitude and Frequency
- People focus on how large and frequent hazards are. The impact of an event depends on its magnitude (energy released) and its frequency (how often it occurs, larger events have less frequency),
- This is the magnitude-frequency relationship that can be described by mathematical equations .
- Geologists have debated the significance of large, infrequent events versus smaller, frequent events in shaping the Earth.
Reactive Response and Recovery
- Recovery attempts after natural disasters depend on the disaster type and the frequency of such events.
- Disaster effects (direct/indirect) impact lives, properties, and the economy, recovery times vary too.
Potential Natural Hazards
- Hazards are listed by type (atmospheric, seismic, geologic, hydrologic, volcanic, wildfire, astronomic, climate change) and then specific hazards within each category. (e.g., atmospheric hazards: hailstorms, ice storms, hurricanes; geologic hazards: landslides, rockfalls)
Hazards by Season
- Different hazards have different seasonal patterns (e.g., wild fires happening more often in drier seasons, avalanches connected to winter)
