1.20 - Hazard Trends Flashcards
What is the key focus of trend analysis in geographical studies?
Identifying patterns and changes over time.
Why is it important to analyze trends in natural disasters?
To predict future occurrences and improve disaster management.
What factors influence trends in natural hazards?
Climate change, urbanization, and population growth.
How does climate change impact natural hazard trends?
It increases the frequency and intensity of extreme weather events.
Why is urbanization a key factor in disaster trends?
It increases exposure to hazards due to higher population density.
What role does technology play in analyzing hazard trends?
It improves data collection, analysis, and forecasting accuracy.
How can past disaster trends inform future planning?
By identifying vulnerable areas and improving mitigation strategies.
What are the challenges in interpreting disaster trends?
Data limitations, reporting inconsistencies, and changing hazard patterns.
Why is population growth a critical factor in hazard trends?
It places more people and infrastructure at risk.
How do global trends in disasters affect policy-making?
They influence decisions on resource allocation and emergency planning.
What type of data is crucial for analyzing hazard trends?
Historical records, satellite imagery, and climate models.
What is the significance of tracking trends in tectonic activity?
To understand seismic patterns and improve early warning systems.
How does deforestation contribute to changing disaster trends?
It increases susceptibility to flooding and landslides.
Why is it important to differentiate between natural variability and human impact?
To accurately assess and respond to disaster risks.
What role do international organizations play in monitoring hazard trends?
They provide data, research, and coordination for disaster response.
How can social media contribute to understanding disaster trends?
By providing real-time information and public perceptions.
What are some methods used to analyze trends in disasters?
Statistical analysis, GIS mapping, and predictive modeling.
What is a key limitation of trend analysis in disaster management?
Uncertainty in future projections and evolving risk factors.
How do economic trends influence disaster preparedness?
They determine funding availability and investment in infrastructure.
Why is public awareness essential in managing disaster trends?
It helps communities prepare and respond effectively.
What major trend has been observed in disaster frequency?
An increase in both frequency and economic costs of disasters.
How does political instability affect disaster management trends?
It can hinder response efforts and resource allocation.
Why is data collection important in tracking disaster trends?
Accurate data helps in identifying patterns and planning interventions.
How does infrastructure development affect hazard trends?
It can either mitigate or exacerbate disaster impacts.
What is the primary goal of analyzing disaster trends?
To enhance resilience and reduce future risks.
