Question

A. Describe the hazards created by a named volcanic eruption.
Name of volcano: Eyjafjallajökull volcano in iceland.
B. Suggest why people live in areas which experience earthquakes and volcanoes. Give any 6 reasons.
DESCRIBE THE WORK LIKE AN EXPLORER (not important)

Answer 1

Answer:

Vibrations often occur in volcanic regions as well, for two reasons there are tectonic faults and lava movements in volcanoes. Such earthquakes are an early warning of volcanic eruptions.......

Explanation:

Earthquake or earthquake is the shaking of the Earth's surface. It is caused by seismic waves arising due to the sudden release of energy in the Earth's lithosphere. Earthquakes can be very violent, and have the potential to cause an entire city to collapse and hurt people in a few moments.

Earthquakes are measured with an earthquake meter, called a seismograph. The moment magnitude magnitude of an earthquake is traditionally measured, or the relative and obsolete Richter magnitude is taken. An earthquake of magnitude 3 or less Richter is often imperceptible, while an earthquake of magnitude 6 Richter causes severe damage in large areas. The intensity of the shaking is measured on the developed mercury scale.

On the surface of the Earth, an earthquake manifests itself by moving or displacing the land. When a major earthquake occurs in the epicenter offshore, it causes a substantial amount of displacement at the seashore, causing tsunamis. Earthquake tremors can sometimes cause landslides and volcanic activities.

In the most general sense, the word earthquake is used to describe any seismic event, a natural event]) or an event caused by humans — which produce seismic waves). Earthquakes are often caused by geological faults, large amounts of gas migration, mainly methane deep inside the Earth, volcanoes, landslides and nuclear tests are the main faults.

The starting point of earthquake is called center or hypo center. The word epicenter means the point just above the ground level.
