FAQs on Mind Map: Earthquake - Geography for UPSC CSE

1. What causes earthquakes?
Ans. Earthquakes are caused by the sudden release of energy in the Earth's crust, usually due to the movement of tectonic plates. When these plates collide, slide past each other, or separate, it can create seismic waves that result in an earthquake.
2. How can earthquakes be measured?
Ans. Earthquakes are measured using a device called a seismograph. The seismograph records the shaking of the ground during an earthquake and produces a graph called a seismogram. This graph provides information about the magnitude, duration, and frequency of the earthquake.
3. Can earthquakes be predicted?
Ans. Although scientists can't predict exactly when or where an earthquake will occur, they can determine areas with high earthquake risks based on historical data and the movement of tectonic plates. However, predicting the exact time and location of an earthquake is still a significant challenge.
4. How do earthquakes impact the environment?
Ans. Earthquakes can have various environmental impacts. They can cause landslides, tsunamis, and avalanches, leading to the destruction of landscapes and habitats. Additionally, earthquakes can disrupt ecosystems, damage infrastructure, and even trigger secondary effects such as water and air pollution.
5. What safety measures can be taken during an earthquake?
Ans. During an earthquake, it is important to take immediate safety measures. These include taking cover under sturdy furniture or in a doorway, staying away from windows and other glass objects, and avoiding elevators. It is also crucial to have an emergency kit ready with essential supplies and to practice earthquake drills to be prepared for such events.
