- 1. CAUSE AND EFFECTS TO HUMAN AND ENVIRONMENT NATURAL DISASTER S
- 2. LEARNING OBJECTIVE: After going through the lesson, you are expected to: ● Explain the causes and effects of natural disasters on humans and the environment
- 4. 1. It is a frightening funnel and a swirling vortex! FLASH NEWS!
- 5. 2. It is a monstrous made from overflowing rain!
- 6. 3. It is a massive, watery crest with incredible power!
- 7. 4. It is a crust-shaking, seismic seizure!
- 8. 5. It is an intense, hot molten mayhem with molten lava!
- 9. I BRING HARM. I LEAVE DEBRIS AND A FEW SURVIVORS. WHAT AM I?
- 10. CAUSE AND EFFECTS TO HUMAN AND ENVIRONMENT NATURAL DISASTER S
- 12. OVERVIEW 01 What is natural disaster? Impacts to environment and to humans LAND DISASTERS 02 Earthquake AIR DISASTERS 03 Typhoon WATER DISASTERS 04 Flooding OTHERS 05 Disaster manangement TABLE OF CONTENTS

- 14. Natural Disaster catastrophic events with atmospheric, geological, and hydrological origins.
- 16. Natural Disaster defines it as “a natural process or phenomenon that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage” PAGAS A

- 25. Earthquake
- 27. Earthquake happens when two blocks of the earth suddenly slip past one another
- 29. Focus The location below the earth’s surface where the earthquake starts
- 31. Epicenter The location directly above it, on the surface of the earth,
- 32. Causes of Earthquake imbalance in any part of the crust of the earth. Other causes of earthquakes occur due to volcanic eruptions, faulting and folding, gaseous expansion, and contraction inside the earth
- 33. Effects of Earthquakes Landslides – Landmasses with weak foundations cause landslides and debris falls, which damage settlements and transport systems on the lower slope segments
- 35. Effects of Earthquakes Damage to Life and property - Structures such as buildings, roads, rails, factories, dams, and bridges suffer colossal damage from earthquakes, thus causing a heavy loss for both human life and property
- 37. Effects of Earthquakes Damages to Government Infrastructure – the various cities and towns are worst affected due to a large concentration of human population, commercial complexes, and residential areas.
- 38. Effects of Earthquakes Fire Hazard – Severe fire outbreaks in buildings, houses, and factories occur when earthquakes produce strong oscillations
- 40. Effects of Earthquakes Landmass Deformation – Due to a strong vibration produced by earthquakes, the shapes of landmasses are altered
- 42. Effects of Earthquakes Tsunamis - The seismic waves caused by the earthquakes traveling through seawater, generate high sea waves, and cause significant loss of life and property.
- 44. Effects of Earthquakes Tsunamis - The seismic waves caused by the earthquakes traveling through seawater, generate high sea waves, and cause significant loss of life and property.
- 45. Effects of Earthquakes Flash Floods - Strong seismic events result in the damages of dams and cause severe flash floods

- 49. TYPHOONS Tropical cyclone is a rapidly rotating warm air and water created from a low pressure area. It always forms over oceans where sea surface temperature is greater than 26 degrees Celsius.
- 52. TORNADO
- 53. TORNADO a narrow, violently rotating column of air that extends from a thunderstorm to the ground.
- 55. OVERVIEW 01 What is natural disaster? Impacts to environment and to humans LAND DISASTERS 02 Earthquake AIR DISASTERS 03 Typhoon WATER DISASTERS 04 Flooding OTHERS 05 Disaster manangement TABLE OF CONTENTS
- 58. Floods a relatively high flow of water discharged from the river and stream network, which sets the riverbank margins to overflow and lead to the submerging of low land areas surrounding the riverbed. It is essentially a phenomenon.

- Today, warning facilities are already available, and by mitigation measures, loss of lives and properties can be minimized. The meteorological services around the world provide warnings to the public on some of the weather-related natural disasters.
- government agencies that the public can rely on. Since natural disasters cannot be prevented, taking proper long-term and short-term disaster mitigation measures can minimize life and property loss
- Floods arise from abnormally heavy rains, dam failures, snow melts, and river blockages. Flood disasters rank second only to droughts in the total number of people affected worldwide
