भूकंप क्या होता है ? #Earthquake | cause of Earthquake | #Seismic Zone | #SeismicWaves

#earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” #Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another. The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth’s crust. (See the table of major earthquakes.) ✔️ earthquake epicenters Global seismic centers for earthquakes of magnitude 5.5 and greater occurring between 1975 and 1999. Little was understood about earthquakes until the emergence of seismology at the beginning of the 20th century. Seismology, which involves the scientific study of all aspects of earthquakes, has yielded answers to such long-standing questions as why and how earthquakes occur. ✔️ San Francisco earthquake of 1906 San Francisco earthquake of 1906 Crowds watching the fires set off by the earthquake in San Francisco in 1906, photo by Arnold Genthe. About 50,000 earthquakes large enough to be noticed without the aid of instruments occur annually over the entire Earth. Of these, approximately 100 are of sufficient size to produce substantial damage if their centres are near areas of habitation. Very great earthquakes occur on average about once per year. Over the centuries they have been responsible for millions of deaths and an incalculable amount of damage to property. 🍣🍣🍣🍣🍣🍣🍣🍣🍣🍣 Welcome to #ParikshaJunction . आपके अपने #YouTube channel: Pariksha Junction™️ पर आपका स्वागत हैं | 👉 परीक्षा जंक्शन / Pariksha Junction - मतलब एक ऐसा फ्री Educational Channel जिसके माध्यम से समस्त प्रतियोगी परीक्षाओं जैसे - UPSC, SSC, UPSSSC, BANKING, RAILWAY व अन्य सभी एक दिवसीय परीक्षाओं की तैयारी कर, आप अपने जीवन को सफल व अपने माता-पिता के बड़े सपनो को पूरा कर सकते हैं | 👉साथ ही साथ इसी Channel के माध्यम से #CUET, B.A, B.Sc., B.Ed. आदि जैसी Graduate Level परिक्षाओं की भी तैयारी कर अपने परिणाम को और भी अच्छा कर सकते हैं | Facebook📌 https://www.facebook.com/ParikshaJn X / Twitter📌 https://x.com/ParikshaJn
