Earthquakes are sudden, violent tremors in the Earth's crust caused, natural calamities

Earthquakes are sudden, violent tremors in the Earth's crust caused by the shifting of tectonic plates along fault lines. As primary natural calamities, they can trigger devastating secondary events like tsunamis, landslides, soil liquefaction, and structural collapses.Key Earthquake MechanismsTectonic Plates: The Earth's outer crust is fractured into moving puzzle pieces. Where they collide, pull apart, or slide past one another, friction creates massive stress.Energy Release: When stress overcomes the rock's friction, it snaps and releases massive amounts of energy in the form of seismic waves, which shake the ground.Focal Points: The underground point where the quake begins is the hypocenter, while the spot directly above it on the surface is the epicenter.Secondary Natural DisastersOften, the initial earthquake is just the beginning. The resulting ground shaking can trigger several cascading calamities:Tsunamis: Massive ocean waves generated by underwater earthquakes or coastal landslides.Landslides: The shaking can destabilize loose soil and steep rock formations, causing debris flows.Soil Liquefaction: Water-saturated sediment can lose its strength and behave like a liquid, causing buildings to sink.Fires & Infrastructure Failure: Broken gas lines, downed power lines, and damaged dams often lead to severe fires and flooding.Preparedness and SafetyWhile earthquakes cannot be predicted or prevented, you can significantly reduce risk through proper planning:Drop, Cover, and Hold On: The recommended immediate safety action during shaking.Preparedness Kits: Keep an emergency supply of water, non-perishable food, flashlights, and a first-aid kit.Structural Engineering: Upgrading and retrofitting infrastructure helps buildings withstand seismic forces.To learn more about disaster preparedness and what to do before, during, and after an earthquake, you can check the guidelines provided by the World Health Organization. 🏫 CDAF SAINIK ACADEMY Bangla Bazar – 417 Eldico Udyan-1 Ravi Khand, Lucknow (Uttar Pradesh) 📞 Mob: 9415087674, 8299859259 🌐 Website http://cdafnda.com http://cdafnda.org 📺 YouTube Channel https://www.youtube.com/channel/UCR4H 📘 Facebook Pages   / cdafcochingi     / cdafsainikac   ━━━━━━━━━━━━━━━━━━━━━━ INSV Kaundinya NDA CDS Indian Navy GK Defence GK India Indian Navy exam preparation INSV Kaundinya facts INSV Kaundinya in hindi INSV Kaundinya explained Indian Navy latest news #INSVKaundinya #IndianNavy #MaritimeHeritage # #sainik_school_one_day #sainik_school_online_registration #sainik_school_on_fire #sainik_school_online_apply_2022 #maths #basic_mathematics #geometry #sainik_school_maths # FRESH BATCHES FOR SAINIK/ MILITARY/ RIMC STARTS FROM EVERY MONDAY; Fee Discount Upto 30% based on Scholarship test OFFLINE CLASSES / ONLINE CLASSES/ /LUCKNOW SAINK SCHOOL (Cap MANOJ PANDEY SAINIK SCHOOL for 7th class Boys and 9th class Boys and girls) FOR 6TH CLASS, 7TH CLASS, 8TH CLASS AND 9TH CLASS SAINIK SCHOOL / MILITARY SCHOOL / RIMC ENTRANCE/ LUCKNOW SAINK SCHOOL (Cap MANOJ PANDEY SAINIK SCHOOL for 7th class Boys and 9th class Boys and girls) FOR 6TH CLASS, 7TH CLASS, 8TH CLASS AND 9TH CLASS fresh starts baches every week Timing MORNING 9am to 1pm MORNING 10.30am to 12.30pm (PROBLEM SOLVING SESSION) EVENING 3.30 pm to 7.30pm Evening 4.30pm to 8pm EVENING 4.30 pm TO 8.30pm CDAF SAINIK ACADEMY BANGLA BAZAR- 417 Eldico udyan-1,ravi khand lucknow
