FLOOD AND SOIL EROSION

What is Flood?

A flood can be a temporary flood that has been caused by a rapid stream flow, massive rainfall, collapsed dams, melting of snow, storm surges and tsunamis

. Flood can bring a massive loss of life as it brings disease that causes health problems. However, it also affects the structural integrity of properties such as roadways, bridges,  buildings, houses, powerplants, and factories.

 

What is Soil Erosion?

A soil erosion can be caused naturally because of a wind,  rain,  overgrazing,  and human made activities like deforestation that results to transportation of a soil from one place to another.

Flooding isn't the only cause of destruction of the structures but it also can be caused by soil erosion as it erodes and breaks the integrity of buildings.

Hazards That May Happen in the

Event of Earthquakes and Volcanic Eruption 


Tremors and volcanoes cause harm not exclusively to people and their structures, however to the earth and natural life. Seismic tremors can cause harm to life due to shaking. Moreover, it can bring tsunamis and avalanches. Volcanoes can cause harm by debris streams, arrival of gases, mudflows, magma streams, and avalanches. 

Earthquakes might be related with volcanic perils, particularly as an antecedent to an ejection. Be that as it may, quakes can cause fiascos without the assistance of a spring of gushing lava. Tremors produce seismic waves that can discharge incredible vitality. In any case, if the tremor happens in a territory that isn't populated, it's anything but a human fiasco. 

Volcanic harm happens in view of the items produced by an ejection. The kind of ejection is significant. For example, a tranquil magma emission gives human sufficient opportunity to empty a zone. Savage ejections that happen with small notice are in some cases hard to evade. Numerous individuals don't accept that volcanoes can cause a lot of harm, and decline to move. 

Volcanoes emit in an unexpected way, contingent upon the organization and thickness of the ejecting magma, the measure of gas in the parent magma, and power of the emission. Volcanoes that emit magma that is low in silica and gases will in general be "calm," for the most part spilling out surges of genuinely liquid magma. Kilaeua fountain of liquid magma in Hawaii is a genuine model. Volcanoes that emit silica-rich magmas, and that have a great deal of gas, will in general be hazardous. This produces enormous billows of volcanic debris, debris streams, and gases. The free material created by these ejections regularly turns into the crude material for avalanches or mudflows. can cause risky blasts just as delicate magma streams.
