How did human involvement affect the disaster?

Tropical cyclones can cause heavy damage when it crosses land. Gale force winds are winds over the speed of 62km/h can tear roofs off buildings, uproot trees and threaten human live . Cyclones can destroy the canopy of a forest, destroying habitats. Cyclones can damage coral when it’s around coral reef; if the cyclone is extreme it can cause a tornado over the sea which sucks up fishes and other marine animals.

An example of one from history including a death toll and map.

Typhoon Tip was the most intense Cyclone in Philippines on October 1979. During the Cyclone 99 people died after the Typhoon Tip. 27 destroyed bridges, Over 22,000 homes were flooded and at least 11,000 people were left homeless. Typhoon Tip destroyed 27 bridges.

Human’s involvement affects the disaster because of population growth, migrations, increasing coastal settlement and global warming.

Could anything have been done to prevent it or reduce the damage?
