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.

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: What are the procedures for earthquake drill to be conducted at daycare or preschool? A:  The earthquake drill for a daycare or preschool is necessary to tackle the emergency situation. An individual should be aware about how to be safe during the earthquake after the disaster. Below are few suggestions from Federal Emergency Management Agency (FEMA): To do before an earthquake -Make your building more earthquake-proof -Include earthquake preparedness in your emergency plans -Teach children and staff what to do if an earthquake happens Prepare an emergency kit The emergency kit should include -Flashlight with extra bulbs and extra batteries -Portable battery-operated radio and extra batteries -First aid kit and manual -Roster of children with addresses and their parents’ emergency contact information -Emergency food and water -Essential medicines and medical supplies -Diapers and wipes -Blankets -Work gloves -Sturdy boots or shoes Earthquake drill -Identify a safe gathering place ou

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 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.

September 7, 2021: A light earthquake of magnitude 3.5 has been recorded in Midland, Texas today. According to the United States Geological Survey (USGS), the epicenter was located 16 km NNW of Midland, Texas. The earthquake occurred at 72 km depth. The tremor was felt by the people of Midland, Stanton, Gardendale and Odessa.

September 4, 2021: A light earthquake of magnitude 3.9 has been felt in Vijayapura (also called Bijapur) in Karnataka state of India today at 11:49 pm. According to the Karnataka State Natural Disaster Monitoring Centre (KSNDMC), the earthquake occurred in Kolhapur district of Maharashtra, bordered with Karnataka. The epicenter was located 19 km W of Kolhapur, Maharashtra, the National Center for Seismology confirmed. The earthquake occurred at 39 km depth. The tremor was felt in various cities of Maharashtra and Karnataka. People living in Vijayapura City, Basavana Bagewadi, Tikota, Indi and Sindagi areas ran out of their houses immediately after the tremor. No preliminary damage or injuries have been reported.

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

Q: Distinguish between volcanic earthquake and explosion earthquake . A: There are four different types of earthquakes: tectonic, volcanic, collapse and explosion. A volcanic earthquake is associated with volcanic activity due to the movement of magma beneath the surface of the Earth. Volcanic earthquake is caused by slip on a fault near a volcano. An explosion earthquake is an earthquake activity triggered due to the detonation of a nuclear and/or chemical device. According to the United States Geological Survey (USGS), the underground thermonuclear tests conducted by the U.S. at the western end of the Aleutian Islands in Amchitka in 1971 caused energy release equivalent to a magnitude 6.9 earthquake.
