Today we are going to discuss tectonic hazards. These are events caused by the movement of Earth’s lithospheric plates. Can anyone mention some examples of tectonic hazards?
Isn't the earthquake one of them?
Correct! Earthquakes are a primary example of tectonic hazards. Can anyone think of another?
What about tsunamis?
Absolutely! Tsunamis are often caused by underwater earthquakes. Let’s remember this with the mnemonic ‘E.T. for Tectonic’ – Earthquakes and Tsunamis. Can someone explain why they might be dangerous?
They can cause a lot of destruction and loss of life.
Exactly. Knowing about these hazards helps us prepare effectively. Let’s summarize: tectonic hazards include earthquakes and tsunamis, which are caused by movements of the Earth’s plates.
Exploring Climatic Hazards

Moving on to climatic hazards, who can tell me what these are?
They are hazards related to weather, like hurricanes and floods!
That's right! Climatic hazards can have devastating effects on communities. Let's remember, we can use the acronym ‘HFDT’ – Hurricanes, Floods, Droughts, Tornadoes. Why is it important to study these hazards?
So we can be better prepared for them!
Exactly! Understanding might save lives. Let’s summarize: climatic hazards include hurricanes, floods, droughts, and tornadoes. They pose risks to human life and infrastructure.
Discussing Biological Hazards

Now, let’s discuss biological hazards. Who can explain what they might be?
They could be pest outbreaks or diseases, right?
Great! Biological hazards involve pest outbreaks and epidemics linked to environmental factors. Let's use the rhyme 'Bugs in the air, beware – outbreaks can scare!' What impacts do these hazards have?
They can spread quickly and affect a lot of people’s health.
Indeed, they can affect public health and resources. Let’s summarize: biological hazards are related to environmental factors causing pest outbreaks and epidemics.

Let’s apply our knowledge to a case study. Can anyone share an example of a tectonic hazard event?
The 2015 Nepal Earthquake!
Excellent! What caused this earthquake?
It was caused by the collision of the Indian and Eurasian plates.
Correct! This event caused significant destruction. Why do we study such events?
To understand how to prepare better for the future!
Exactly! Summarizing, the Nepal Earthquake is a prime example of how tectonic hazards manifest and impact human life.

Quick Overview
Standard
In this section, we delve into the classification of natural hazards resulting from geological, atmospheric, and biological processes. Understanding these hazards is critical for disaster preparedness and risk reduction, illustrated by the case study of the 2015 Nepal Earthquake.
Detailed
Types of Natural Hazards
Physical geography aids in comprehending natural hazards that arise from Earth's intrinsic processes. These hazards can be categorized into three main types:
- Tectonic Hazards: These are caused by the movements of the Earth's lithosphere, which lead to phenomena like earthquakes, tsunamis, and volcanic eruptions. For example, the 2015 Nepal Earthquake was a tectonic event induced by the collision of the Indian and Eurasian plates.
- Climatic Hazards: These include various weather-related events that pose risks to life and property, such as floods, droughts, hurricanes, and tornadoes. Understanding climatic patterns can significantly aid in disaster preparedness and response.
- Biological Hazards: While less commonly discussed, biological hazards stem from pest outbreaks and epidemics, particularly those triggered by environmental conditions.
Overall, a thorough understanding of these hazards enables us to improve planning, enhance disaster preparedness, and promote sustainable development, making it a crucial component of physical geography.
