- 2. LEARNING OBJECTIVE: After going throughthe lesson, you are expected to: ● Explain the causes and effects of natural disasters on humans and the environment
- 4. 1. It isa frightening funnel and a swirling vortex! FLASH NEWS!
- 5. 2. It isa monstrous made from overflowing rain!
- 6. 3. It isa massive, watery crest with incredible power!
- 7. 4. It isa crust-shaking, seismic seizure!
- 8. 5. It isan intense, hot molten mayhem with molten lava!
- 9. I BRING HARM.I LEAVE DEBRIS AND A FEW SURVIVORS. WHAT AM I?

- 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

- 27. Earthquake happens when two blocksof the earth suddenly slip past one another
- 29. Focus The location below the earth’ssurface where the earthquake starts
- 31. Epicenter The location directly above it,on the surface of the earth,
- 32. Causes of Earthquake imbalancein 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 Damageto 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 Damagesto 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 FireHazard – Severe fire outbreaks in buildings, houses, and factories occur when earthquakes produce strong oscillations
- 40. Effects of Earthquakes LandmassDeformation – 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 FlashFloods - Strong seismic events result in the damages of dams and cause severe flash floods

- 49. TYPHOONS Tropical cyclone isa 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.

- 53. TORNADO a narrow, violentlyrotating column of air that extends from a thunderstorm to the ground.

- 58. Floods a relatively highflow 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.

- #6 Identify the natural calamities described by the weather anchor on the local news. After you find out, unscramble the circled letters to answer the riddle.
- #7 Identify the natural calamities described by the weather anchor on the local news. After you find out, unscramble the circled letters to answer the riddle.
- #8 Identify the natural calamities described by the weather anchor on the local news. After you find out, unscramble the circled letters to answer the riddle.
- #9 Identify the natural calamities described by the weather anchor on the local news. After you find out, unscramble the circled letters to answer the riddle.
- #10 Identify the natural calamities described by the weather anchor on the local news. After you find out, unscramble the circled letters to answer the riddle.
- #17 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.
- #22 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
- #59 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
