Two Types of Meteorological Hazards

a) Hurricanes (Tropical Cyclones): Hurricanes are intense storms that form over warm ocean waters, characterized by strong winds (exceeding 74 mph), heavy rainfall, and storm surges. These storms can cause widespread destruction along coastlines, leading to flooding, infrastructure damage, and loss of life. For instance, Hurricane Katrina in 2005 devastated New Orleans, causing significant flooding and destruction.

b) Tornadoes: Tornadoes are violent, rotating columns of air that extend from thunderstorms to the ground. They result in high-speed winds that can reach up to 300 mph, causing severe damage within a narrow path. Tornadoes are known for their destructive force, uprooting trees, destroying buildings, and causing fatalities. The Tornado Alley region in the central United States is particularly prone to tornadoes, with occurrences causing significant destruction.

Q4c) Differentiate between structural and non-structural mitigation.

Ans) Comparison Between Structural and Non-Structural Mitigation Measures:

Q4d) Write a brief note on the Disaster Crunch Model?

Ans) The Disaster Crunch Model, proposed by Dr. Enrico Quarantelli, is a conceptual framework that outlines the phases and dynamics of public behaviour during disasters. It focuses on the social aspects of disasters, particularly how individuals and communities respond to and recover from catastrophic events.

Key Aspects:

a) Pre-impact Phase: This phase involves the period before the disaster strikes, highlighting preparedness measures, warning systems, and preventive actions taken by individuals and institutions.

b) Impact Phase: The moment the disaster occurs, where the focus is on the immediate response, rescue operations, and the chaos that ensues as people deal with the immediate effects.

c) Heroic Phase: Characterized by a surge in solidarity, altruism, and emergency response efforts from both official and spontaneous sources to aid victims and address urgent needs.

d) Honeymoon Phase: Follows the heroic phase, marked by a sense of unity and support, where communities come together to rebuild and recover.

e) Disillusionment Phase: This phase reveals the shortcomings in relief efforts, bureaucratic hurdles, and challenges in recovery, leading to frustration and a decline in public morale.

f) Reconstruction Phase: The final phase involves long-term recovery, rebuilding infrastructure, restoring normalcy, and adapting to the changes brought about by the disaster.

Q5) Write short notes on any five of the following in about 100 words each:

Q5a) Types of drought

Ans) Drought, a prolonged and severe lack of precipitation leading to water scarcity, can manifest in various forms:

a) Meteorological Drought: Occurs due to a prolonged period of below-average precipitation. It's characterized by a deficit in rainfall and dry weather conditions impacting water sources.

b) Agricultural Drought: Results from inadequate soil moisture levels affecting crop growth and agriculture. Insufficient rainfall or irrigation can lead to crop failures and impact food production.

c) Hydrological Drought: Involves low water levels in rivers, reservoirs, and groundwater due to reduced precipitation, affecting water supply for various purposes, including drinking water, industries, and irrigation.

d) Socioeconomic Drought: Arises when water shortages from meteorological, agricultural, or hydrological droughts impact human populations, leading to economic losses, water scarcity, and societal disruptions.

Q5b) Gender based violence

Ans) Gender-based violence (GBV) refers to any harmful act that is perpetrated against an individual's will and is based on gender norms and inequalities. It encompasses physical, sexual, psychological, or economic harm inflicted on an individual due to their gender. GBV disproportionately affects women and girls, but it can also impact men and non-binary individuals. This form of violence includes domestic violence, sexual harassment, rape, forced marriages, honour killings, and trafficking. GBV is rooted in societal power imbalances, cultural norms, and discriminatory practices, requiring comprehensive efforts including education, policy interventions, and community engagement to prevent and address this pervasive issue.

Q5c) Steps involved in hazard identification and risk assessment

a) Hazard Identification: Identify and list potential hazards that could cause harm, including natural events, technological failures, human errors, or deliberate acts.

b) Risk Analysis: Assess the likelihood and severity of each identified hazard's impact on people, property, and the environment.

c) Exposure Assessment: Evaluate the extent of exposure to hazards, considering the population, assets, and infrastructure in the affected area.

d) Vulnerability Assessment: Analyse the vulnerabilities of people, structures, and systems to the identified hazards.

e) Risk Estimation: Estimate the level of risk by combining the probability and consequences of each hazard.

f) Risk Evaluation: Determine the acceptability of the identified risks and prioritize them for mitigation or control measures based on their severity and likelihood.

Q5d) Types of forest fires

Ans) Forest fires can be categorized into two primary types based on their nature and behaviour:

a) Surface Fires: These fires burn through the forest floor's surface litter, including dry leaves, twigs, and debris. They usually move relatively slowly and do not reach the forest canopy, causing minimal damage to trees and wildlife. Surface fires play a natural role in forest ecosystems by clearing out underbrush and dead vegetation.

b) Crown Fires: These fires spread rapidly and intensely, burning through the forest canopy, engulfing trees, and vegetation at the top. Crown fires are extremely destructive, spreading quickly with high intensity, and can cause significant damage to large areas of forest, resulting in severe ecological impacts and challenges in firefighting efforts.

Q5e) Four stages of warning system for tropical cyclone

Ans) The warning system for tropical cyclones typically involves four stages:

a) Watch: The initial stage, where meteorological agencies issue a watch indicating the possibility of a cyclone impacting a specific area within a specified timeframe. It alerts authorities and the public to start preparations and monitor updates closely.

b) Advisory: An advisory is issued when there is a higher probability of a cyclone striking an area. It provides detailed information on the cyclone's location, intensity, expected path, and potential impact, enabling people to take necessary precautions.

c) Warning: A warning is issued when a cyclone is imminent or already occurring. It signifies that the cyclone is expected to affect the warned area, urging immediate action for evacuation, securing property, and seeking shelter.

d) All-Clear: Issued after the cyclone has passed or the threat has significantly diminished. It indicates that conditions are safe, allowing people to return to normal activities.
