Study Notes
Hazard Classification
- Hazards and disasters are classified into two main categories: Natural and Human-induced.
Disaster Definition
- A disaster is an event arising out of a hazard event.
Hazard Definition
- A hazard is a situation where there is a threat to property and lives from calamities.
Consequences of Disasters
- Disasters can result in loss of life, damage to property, and environmental damage.
Earthquake Study
- The scientific study of earthquakes is called Seismology.
- The instrument used to measure earthquake intensity is called a Seismograph.
- The primary result of earthquakes is building and bridge collapse, rupture of water and gas pipelines, and change in course of river and creation of new islands.
Tropical Cyclones
- Tropical cyclones can result in fierce wind, heavy rain, and storm surge.
Flood Causes
- The major man-made causes of floods are deforestation, siltation, and bursting of dams.
Biological Disasters
- Mass killing diseases can be referred to as biological disasters.
Disaster Prevention
- The role of government officials, media, and the public is important in disaster prevention.
- Important measures to be taken in community-level disaster preparedness include increased awareness, provision of early and timely warning, and land-use planning.
Earthquake Terminology
- A point on the surface of the earth vertically above the focus is known as the epicenter.
- The instrument used for recording the occurrences of earthquakes is a seismograph.
Seismic Activity
- The circum-Pacific belt witnesses the highest seismic earthquake activity in the world.
India's Disaster Scenario
- Flood is the most prominent disaster in India.
Volcanic Disasters
- The volcanic eruption responsible for raising the temperature of the Northern Hemisphere by 1.2°C is Mt. Pinatubo.
- The major controlling systems for reduction of volcanic disaster are prediction for early warning of eruption and timely evacuation and relief work.
Volcanic Eruption Prediction
- Techniques used for prediction of early warning of eruption include Electric Distance Measures, Tilt Meters, GPS, and Satellite Inferring Radar.
Earthquake Types
- Shallow earthquakes, less than 20 km deep, are associated with convergent plate boundaries.
Earthquake Triggers
- Earthquakes can trigger tsunamis, intense ground shaking, and landslides.
