Natural disasters

The most severe natural disasters worldwide

Natural catastrophes influence the lives of people around the world. Earthquakes, volcanoes and, as a result, tsunamis, occur mainly at the edges of tectonic plates. In Europe or the eastern US, we are mostly spared from this. Other countries, e.g., the Pacific countries, are much more affected by this.
Natural disasters result from natural phenomena such as weather or geological disturbances and have a significant impact. Examples of natural disasters include earthquakes, hurricanes, tornadoes, floods, forest fires, volcanic eruptions, tsunamis, landslides and droughts.

These events can cause widespread damage to homes, businesses, infrastructure, and natural resources, as well as loss of life. Natural disasters can also have significant economic consequences, causing billions of dollars in damage and losses in the affected regions.

On the following pages, we evaluate earthquakes, volcanoes, tropical storms and tsunamis by highlighting particularly affected countries and illustrating the damage, as well as frequency, of the events.

Earthquakes

Earthquakes

Earthquakes occur naturally in the lithosphere, the outer rock layers of the earth. Like volcanoes and tsunamis, they occur mainly at the edges of tectonic plates.

Volcanoes

Volcanoes

Volcanoes are a natural geological formation that occurs when molten rock and gases from the Earth's interior reach the surface. They are mostly formed in the regions where tectonic plates collide.

Tsunamis

Tsunamis

As a result of earthquakes and volcanoes, not only land masses move, but often also water masses. The more violent the displacement, the stronger the tsunamis, which are hardly visible on the open sea.

Tropical cyclones

Tropical cyclones

Hurricanes, cyclones and typhoons form over warm ocean waters in tropical regions. They do not form in cold regions; the water surface must be at least 26 degrees warm for a hurricane to form.

Protective measures

Although natural disasters are beyond human control, measures can be taken to mitigate their impact and reduce the risk of loss of life and property damage. These include disaster preparedness planning, early warning systems, evacuation procedures, infrastructure improvements, and land use planning that takes into account the risk of natural hazards.
