QUARTER 1-MODULE 18 HYDROMETEOROLOGICAL PHENOMENA AND HAZARD
objectives After going through this module, you are expected to: 1. identify places in the Philippines that are prone to hydrometeorological hazards like tropical cyclones, monsoons, floods, or ipo-ipo using hazard map; and 2. explain why it is important to identify places that are prone to hydrometeorological hazards
Hydrometeorological Phenomena and Hazards The Philippines is a Southeast Asian archipelago renowned for its beauty but also susceptible to a wide array of hydrometeorological hazards, which can cause significant damage and disrupt life. This presentation will explore the nature and impacts of these phenomena.

Common Hydrometeorological Hazards in the Philippines 1 Typhoons The Philippines is located within the typhoon belt, making it one of the most typhoon-prone countries in the world. 2 Floods Heavy rainfall, particularly during typhoon seasons, can lead to widespread flooding, affecting both urban and rural areas. 3 Landslides Steep slopes and intense rainfall can trigger landslides, which pose a significant threat to communities living in mountainous regions. 4 Monsoons - A monsoon is a seasonal wind and rain pattern, and the word “monsoon” is believed to have originated from the Arabic word mawsim (season), via Portuguese and the Dutch monsun . .
Typhoons and Tropical Cyclones Formation Typhoons form over warm ocean waters, drawing energy from the heat and moisture. They are characterized by strong winds, heavy rainfall, and storm surges. Impacts Typhoons can cause widespread damage to infrastructure, agriculture, and human settlements. They can also lead to displacement, power outages, and disruption of essential services. Mitigation Early warning systems, evacuation plans, and robust infrastructure are vital for mitigating typhoon risks. Public awareness campaigns and disaster preparedness drills play a crucial role in ensuring community safety.
Top 19 province at risk to typhoons Did you know? Typhoon Haiphongin 1881, ranks as number one of the deadliest typhoon that crossed the Philippines. Haiyan(Yolanda) in 2013 is known as deadliest typhoon in modern year.
Top 10 flood prone provinces Northern Luzon, Southeastern Luzon and Eastern Visayas are the areas highly at risk to the occurrence of tropical depressions, tropical storms, typhoons and super typhoons.
Floods and Flash Floods 1 Heavy Rainfall Intense rainfall, often associated with typhoons or monsoon seasons, can overwhelm drainage systems, leading to widespread flooding. 2 River Overflow Elevated water levels in rivers and streams can lead to overflows, inundating surrounding areas and causing significant flooding. 3 Flash Floods Intense rainfall in mountainous areas can trigger rapid and sudden rises in water levels, resulting in flash floods that pose a significant threat to life and property. 4 Consequences Flooding can cause extensive damage to homes, businesses, and infrastructure, leading to loss of life and displacement. It can also contribute to the spread of waterborne diseases, disrupt transportation and economic activities, and cause widespread hardship.
Landslides and Mudflows Heavy Rainfall Intense rainfall saturates the soil, making slopes more susceptible to instability. Slope Failure The saturated soil loses its ability to hold together, leading to the collapse of slopes. Mudflows Landslides can mix with water, creating fast-moving mudflows that can cause significant damage. Impact Landslides can destroy homes, infrastructure, and agricultural land, leading to loss of life and displacement.
Monsoons or Heat Waves El Niño El Niño events, characterized by warmer than average sea surface temperatures in the central Pacific Ocean, can contribute to drought conditions. Agricultural Impacts Drought can severely impact agriculture, leading to crop failure, livestock losses, and food insecurity. Water Scarcity Reduced rainfall and water availability can lead to water scarcity, impacting human consumption, sanitation, and industrial activities. Heat Waves Prolonged periods of extremely high temperatures, often accompanied by high humidity, can lead to heat waves.
Impacts of Hydrometeorological Hazards on Communities Economic Impacts Damage to property, infrastructure, and businesses; loss of livelihoods and income Social Impacts Displacement, homelessness, disruptions to education and healthcare services, and increased vulnerability Environmental Impacts Soil erosion, pollution, and degradation of natural resources, including forests and water bodies Health Impacts Spread of diseases, heat-related illnesses, injuries, and mental health issues
Disaster Risk Reduction and Management Strategies Early Warning Systems Developing and improving early warning systems to provide timely and accurate information about impending hazards. Community Engagement Empowering communities to participate in disaster preparedness, response, and recovery efforts. Infrastructure Resilience Investing in resilient infrastructure, such as flood-resistant buildings and improved drainage systems. Education and Awareness Raising awareness about disaster risks and promoting disaster preparedness knowledge and skills.
