Hi guys 👋 am here after a long gap in this blog let's gets some general information about " EARTHQUAKE " like how it occurs, how to measure the intensity of earthquake, and also how to save ourself from earthquake.
HOW EARTHQUAKES OCCURS :
Earthquakes occur mainly at the border of the plates where to plates slide past each other. Most earthquakes occur in Himalayan region. The actual seismic Centre the " hypocentre, " lies deep below the surface of the earth. The point on the surface of the earth lying immediately abve this is called the " epicenter ". Scientists can determine this point. They measure that time it takes the shock waves to reach the seismic stations and draw circles around the epicentre and two other seismic stations the radius of these Circles corresponds to the measure the time. The points of intersection is the epicentre. Right below the epicenter, beneath the Earth's surface, lies the hypocentre.
HOW TO MEASURE THE INTENSITY OF EARTHQUAKE :
The Intensity of the earthquake is measured by recording the tremors of the earth's surface with I a " seismograph ". These tremors appear when the earthquake waves reach the surface of the earth. Such a seismograph consists of a large, inert weight which stays at rest even during earthquake. A pen is attached to this pendulum when the earth trembles the surface of the earth together with the paper placed their moves to and fro below the writing pendulum which does not move. we can then detect the different types of the waves on the paper which move at different speeds the intensity of the earthquake can be calculated from these wave patterns the intensity is measured on a scale called Richter scale named after its inventor earthquake with the intensity of 2.5 can be felt but ones with an intensity of 8.0 or very destructive.
HOW TO SAVE OURSELF FROM EARTHQUAKE :
Living in a earthquake prone zone is often unavoidable. For instance, almost entire Japan lies in an earthquake prone zone for this reason buildings here are primarily made Earthquakes resistant so that the loss can be minimized. Buildings or built on foundations made of steel balls or from elastic materials such as Bamboo in skyscrapers a pendulum waiting several tons is installed in the upper floor which minimizers the vibration that start in the upper stories when and earthquake occurs if an earthquake occurs
I hope this blog gaved you some knowledge about earthquake.
Thank you guys see you all soon with another blog😊
