2. C. Answer the following briefly. 1. d. C. A magnitude 5.0 earthquake hit Quezon on Thursday. In an advisory, the earthquake was detected about 4:30 a.m. , Thursday, south of Quezon, at a depth of just over 19.3 kilometers (12 miles). Its epicenter was located 24 kilometers (km) west of Guinayangan town. PHIVOLCS said the tectonic earthquake had a depth of 10 km. Residents of Guinayangan, Quezon, reported feeling the earthquake and being awakened by the tremors and rumbling sounds. Hanging objects and motorcycles swung and rocked slightly. PHIVOLCS said damage may be expected, but no aftershocks may occur. a. What type of earthquake hit Guinayangan, Quezon? b. Based on the description of the effects of the earthquake, what was its intensity? Would there be significant damage to the buildings and properties given the magnitude of the earthquake? If you were to experience an earthquake of the same magnitude and intensity, what safety precautions would you take? You learned from your teacher in Earth Science that your hometown happens to be located in a fault zone. Explain to your parents how this will affect your family and what safeguards should you and your family take to protect yourselves.
Answer (1)
a. The earthquake that hit Guinayangan, Quezon, was a tectonic earthquake, as stated in the advisory by PHIVOLCS.b. The intensity of the earthquake can be estimated as Intensity IV to V based on the reported effects, such as people being awakened, hanging objects swaying, and motorcycles rocking slightly. Given its magnitude of 5.0, significant damage to well-built buildings is unlikely, though minor structural damage to weaker structures may occur.If I were to experience an earthquake of the same magnitude and intensity, I would take the following safety precautions:Drop, Cover, and Hold On to protect myself from falling objects.Stay away from windows, glass, or anything that could shatter.If indoors, stay inside and take cover under sturdy furniture.If outdoors, move to an open space away from buildings, trees, and power lines.Be prepared for possible aftershocks by staying alert and having an emergency kit ready.c. Since our hometown is located in a fault zone, our family is at a higher risk of experiencing earthquakes. I would explain to my parents that fault zones are areas where the Earth's plates meet and move, making earthquakes more frequent. To protect ourselves, we should:Ensure our house is earthquake-resistant by reinforcing weak structures.Secure heavy furniture and appliances to prevent them from falling.Have an emergency plan and a "go bag" with essentials like food, water, and first-aid supplies.Participate in earthquake drills to ensure we know what to do when an earthquake occurs.Stay informed about earthquake warnings and advisories from PHIVOLCS.
