WHAT TO DO BEFORE, DURING AND AFTER EARTHQUAKE AND VOLCANIC ERUPTIONS | Science 6 Quarter 4 Week 2

The video opens by highlighting the unpredictability and danger of earthquakes and volcanic eruptions. It emphasizes the importance of knowing what to do before, during, and after such events to ensure safety and minimize damage.

A detailed account of the 2013 Bohol earthquake in the Philippines is presented, described as having a 7.2 magnitude and intensity comparable to 32 Hiroshima atomic bombs. The earthquake caused widespread destruction to churches, houses, and infrastructure, resulting in injuries and fatalities, and left a lasting terror.

Before an earthquake, it's crucial to check building structures for potential hazards, familiarize oneself with evacuation routes, locate emergency facilities like fire extinguishers and first aid kits, prepare an emergency plan, and pack an emergency kit with essentials like water, flashlights, and extra clothes.

During an earthquake, the video advises staying calm. If indoors, take cover under a sturdy desk; if outdoors, stay away from buildings and power lines. Avoid rushing in crowded places to prevent stampedes. If in a car, stop and park away from structures. Do not use elevators, and if near a coastal area, immediately move to higher ground due to tsunami risks.

After an earthquake, find a safe place due to potential aftershocks. Check on family members and seek aid for anyone missing or in trouble. Avoid crossing damaged bridges, check for fires, and stay updated with authorities' instructions to mitigate further risks.

The video transitions to volcanic eruption preparedness, recounting the 2020 Taal volcano eruption. On January 12, 2020, the volcano's alert level quickly escalated to 4, releasing thick smoke, ash, and stones that reached nearby provinces. It caused widespread evacuations, with many residents losing their livelihoods and homes.

Before a volcanic eruption, it's important to be aware of unusual volcanic activity, listen to official safety instructions, prepare emergency supplies such as flashlights, candles, and first aid kits, stock up on food and water, and evacuate early. Prepare masks for protection against ashfall and smog.

During a volcanic eruption, stay indoors and cover your nose and mouth with a mask or damp cloth if ash is present. Keep food and water covered, and stay away from low-lying areas where rocks, lava, and mudflows are likely to occur. Remain in evacuation centers and avoid returning home while the eruption is ongoing.

After a volcanic eruption, do not return home immediately; wait for official instructions confirming it's safe. Avoid crossing bridges during lahar flows. Remove ash from roofs to prevent collapse, check drinking water for clarity, and inspect electrical wiring. Individuals with respiratory issues should remain indoors to avoid inhaling dust and ash, and seek advice before venturing outside.
