GLY 101LEC – Natural Hazards
GLY 101LEC is a course that introduces individuals to the study of natural disasters. Natural hazards are described as “natural phenomena which can lead to the loss of life, injury, or other health impacts, as well as harm to and destruction of property, infrastructure, livelihoods, and services” (UNDRR, 2020). Earthquakes, volcanoes, tsunamis, landslides and and storms and typhoons are examples of natural hazards.
What exactly are natural hazards?
Natural hazards are incidents which take place as the result of processes of nature that involve geological, hydrological, & climatic processes. These occurrences can have serious consequences for the population and the environment. earthquakes. volcanic eruptions, tsunamis, flooding, landslides, and storms are examples of natural dangers.
An earthquake can be described as an abrupt shift or tremor of the crust of the planet. Earthquakes are triggered because of the gradually implemented movement of the tectonic plates, that are massive sections of the earth’s crust. The Richter scale, that quantifies the intensity associated with an earthquake, could be used to measure earthquakes. Earthquakes may cause modest damage to infrastructure and structures as well as substantial destruction and the loss of life.
Volcanoes are mountains or hills with vented areas from which magma, ash, and gas can escape. Volcanoes are formed by the movement of the tectonic plates and are frequently found at their borders. Volcanoes are classified into three types: volcanic shields, cinder cone volcanoes, and stratovolcanoes. Volcanic eruptions may cause anything from little ash fall to catastrophic devastation of structures and infrastructure.
A tsunami is a sequence of very long-wavelength ocean waves (usually several hundred kilometers) created by large-scale ocean disruptions such as earthquakes, volcanic eruptions, and landslides. Tsunamis have the ability to travel across whole ocean basins, causing considerable damage and loss of life when they reach shore.
The movement of rock, soil, or rubble down a slope is referred to as a landslide. A multitude of events, including severe rainfall, earthquakes, and human activities, can produce landslides. Landslides are classified into three types: rockfalls, debris flows, and mudslides. landslides can cause destruction to buildings and other structures as well as catastrophic loss of life.
Typhoons and hurricanes
Tropical cyclones such as hurricanes and typhoons originate over warm ocean waters. These storms are distinguished by high winds, torrential rainfall, and surges of water. The Saffir-Simpson scale, essentially classifies events depending on wind speed, might be used to measure hurricane and typhoon Hurricanes and typhoons may cause modest damage to infrastructure and buildings as well as catastrophic devastation and loss of life.
Natural disasters are phenomena that can have serious consequences for people and the environment. GLY 101LEC is a course that teaches students about natural dangers and how they affect the environment we live in. We’ve talked about some of the unique natural hazards covered in the course, such as volcanoes, quakes, tsunamis, landslides and and hurricanes and typhoons. Natural hazards must be studied so that we can better comprehend how to lessen their effects and safeguard humans and the environment.
