Q: What government agency is tasked to identify the intensity of earthquake in the Philippines? A: The Philippine Institute of Volcanology and Seismology (PHIVOLCS) is tasked to identify the intensity of earthquake in the Philippines.   PHIVOLCS operates 108 seismic monitoring stations all over the Philippines as of December 2020. PHIVOLCS is a service institute of the Department of Science and Technology (DOST). It works providing services for warning, disaster preparedness and mitigation.  Related Post: List of recent natural disasters in Philippines

The 1958 Lituya Bay, Alaska earthquake had a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI (extreme). A tsunami with a record run-up height of 1720 feet occurred in Lituya Bay, Alaska. When did the Lituya Bay Tsunami occur? July 9, 1958 How did the Lituya Bay tsunami start? The 1958 Lituya Bay, Alaska earthquake triggered a major subaerial landslide into Gilbert Inlet at the head of Lituya Bay on the southern coast of Alaska. The landslide impacted the water at high speed generating a giant tsunami. Did anyone died in Lituya Bay tsunami? Five people died in Lituya Bay tsunami. How much land did the Lituya Bay tsunami destroy? Lituya Bay earthquake triggered a rockslide of 40 million cubic yards (30 million cubic meters and about 90 million tons) into the narrow inlet of Lituya Bay, Alaska. Was there a warning for the Lituya Bay tsunami? As the megatsusnmani was caused due to the massive landslide in the area, there was no warning for the Lituya Bay tsunami.

Q: How are earthquakes distributed on the map of earthquake distribution? A:  The earthquakes are mainly distributed at the edge of tectonic plates on the map of earthquake distribution. When earthquakes are plotted on a world map, the earthquake locations look like narrow bands winding through the continents and oceans. The earthquakes are found along the fault line and lines of plate subsidence. Related Post:  How are volcanoes distributed on the map?

Q: How are volcanoes distributed on the map? A:  The volcanoes are distributed mostly o coastline, especially on tectonic plate boundaries. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean.  The volcanoes aren't randomly distributed over the Earth's surface. Most of the volcanoes are concentrated on the edges of continents, along island chains, or beneath the sea. There are around 1500 potentially active volcanoes worldwide.

Q: Where is the epicenter of the hypothetical earthquake? A: The epicenter of a hypothetical earthquake is located at the point where the earthquake starts to rupture. On the other hand, the epicenter is the point on the earth's surface vertically above the hypocenter. The epicenter helps to identify the fault that ruptured causing the earthquake.

Q: What major city in Uzbekistan was destroyed by an earthquake in 1966? A : Tashkent, the capital and largest city of Uzbekistan was destroyed by an earthquake in 1966. An earthquake with magnitude 5.1 had its epicenter in central Tashkent. The 1966 Tashkent earthquake claimed lives of around 15 people and made around 300,000 people homeless. The earthquake destroyed over 80% of the Tashkent city.

Q: How did the Tangshan earthquake happen? A: The Tangshan earthquake happened due to tectonic forces generated by the Amurian tectonic plate interacting with the Eurasian tectonic plate.  The 1976 Tangshan earthquake occurred near a vertical right-lateral strike-slip fault sliding about three meters to the southwest.  The Tangshan earthquake which occurred in 1976 had magnitude of 7.6 located around Tangshan, Hebei, People's Republic of China.

Q:  How did the Ludian earthquake happen? A: The Ludian earthquake happened due to the movement along the Baogunao-Xiaohe fault (left lateral strike-slip) system. The 2014 Ludian earthquake quake was the result of a strike-slip fault, whose fault plane has a southwest-northeast strike.  The Ludian earthquake was of magnitude 6.1 which struck Ludian County, Yunnan, China on 3 August 2014.

Q: What did Poseidon use to cause rough seas and earthquakes? A: Poseidon used trident to cause rough seas and earthquakes. Poseidon used his trident into the seas or into the ground to cause rough seas and earthquakes. Poseidon used his trident to strike a rock upon the hill of the Acropolis to produce a well of seawater.  The trident is the weapon of Poseidon, or the God of the Sea in classical mythology.

Q: What was the Haiti earthquake on the Mercalli scale? A:  The Modified Mercalli Scale (MMI) reading of 2010 Haiti earthquake was an intensity of X. According to the United States Geological Survey, intensity IX on the Modified Mercalli scale (MM) was recorded in Port-au-Prince. The earthquake which occurred on 12 January 2010 was of magnitude 7.0 Mw with epicenter located 25 kilometres west of Port-au-Prince, the capital city of Haiti.

Q: How does the Transamerica pyramid withstand earthquakes? A: Transamerica pyramid consists of network of diagonal trusses at its base which supports it against both horizontal and vertical forces. Transamerica pyramid sits on a 52-feet deep foundation of concrete and steel that was designed to move with the earth during a quake. The Transamerica pyramid is located in the Financial District of San Francisco, California, United States, which is also the second tallest building in the San Francisco skyline.  The Salesforce Tower built in 2018 is currently the tallest building in San Francisco.  Related Post:  Which is the Los Angeles's most earthquake resistant building?

Q: What is LA's most earthquake resistant building? A:   The chance of a magnitude 8.0 or greater earthquake hitting California in the next three decades have been raised from about 4.7% to 7%, a recent California earthquake prediction report by the U.S. Geological Survey has shown.

Q: What is the most calm part of the tropical cyclone called? A: The most calm part of the tropical cyclone is called eye. Eye of the cyclone is the area of lowest atmospheric pressure and has been referred to as 'Calm Center'. Why is the center of cyclone calm? It is calm because the strong converging surface winds can never reach it, as the wind is caused to rotate around the center of the hurricane.

Q: What is the name of the instrument used for measuring earthquake intensity? 1 Richter Scale 2 Seismograph 3 Odometer 4 Speedometer A: The correct answer is  Seismograph .  According to the United States Geological Survey (USGS), A seismograph, or seismometer, is an instrument used to detect and record earthquakes. Seismographs are instruments used to record the motion of the ground during an earthquake. They are installed in the ground throughout the world and operated as part of a seismographic network. The earliest "seismoscope" was invented by the Chinese philosopher Chang Heng in A.D. 132.

Q: The tremors of earthquake were felt at intervals of 15 seconds. The first tremor was felt at 8:54:57 and last tremor was felt at 10:45:12. How many times were the tremors felt? A: The answer is 441 Difference of times = 10:45:12 - 8:54:57 = 9:104:72 - 8:54:57 = 1:50 :15 = 3600 + 3000 + 15 = 6615 seconds. Now, 6615/15 = 441 Still confused?

Tremors of the earthquake: 20 multiple choice questions with answers and explanations For related questions with solutions, click here Earthquake tremors are the shaking movements of the ground caused by the sudden release of energy in the Earth's crust. This release of energy creates seismic waves that propagate through the Earth, causing the ground to shake. Earthquakes can vary in intensity and duration, with tremors ranging from barely noticeable to severe and destructive. Feeling an earthquake tremor can be a startling experience. The sensation is often described as a sudden shaking or
