Hii mate...
Explanation:
BASIC INFORMATION ON EARTHQUAKES
An earthquake is a sudden tremor or movement of earth crust which usually last only for a short time it originates naturally at or below the surface of the earth we often hear some news about the earthquakes only once in a while however earthquakes occur all the time all over the Earth this is because the vast majority of these earthquakes are very weak they are not even noticed major earthquakes are much less frequent but 800 more destructive major earthquakes usually do not occur alone when one such earthquake happens there is usually another one at a nearby location sometimes and earthquake also has fore shocks . Fore shocks are smaller earthquakes that happen in the same place before the larger earthquake occur
EFFECTS OF AN EARTHQUAKE
1️⃣ Earthquakes can cause damage to buildings bridges dams
2️⃣ Earthquakes in many cases may cause great loss of life
3️⃣ Earthquakes can also cause floods and landslides landslides triggered by earthquakes often cause more destruction then the earthquakes themselves
4️⃣ Sometimes the earthquake occur beneath the ocean floor some earthquakes can lead to a Tsunami
CAUSE OF AN EARTHQUAKE
it is known that earthquakes are caused by disturbance deep down inside the uppermost layer of the earth The outermost layer of the Earth is not in a single piece it is broken into a number of plates called lithospheric plates or tectonic plates it is now known that these plates are moving around very slowly just a few mm every year this movement is due to the movement of molten magma inside the earth the movement of these plates cause changes on the surface of Earth which may cause an earthquake the rest of the plates how I will keep on moving this causes attention to build up in the plates when the force of moving plates overcomes the friction at the edges all of their stored energy gets released the earth shakes around this point the vibration at the point of the release of the energy give rise to shop for seismic waves
MEASURING AN EARTHQUAKE
The destruction caused by an earthquake depends on many factors one major factor is its intensity Geologists usually express the intensity open earthquake in terms of a magnitude on the the scale known as the richter scale
SAFETY PRECAUTIONS DURING EARTHQUAKES
1️⃣ TAKE SHELTER UNDER A TABLE AND STAY THERE TILL THE SHAKING STOPS
2️⃣ STAY AWAY FROM TALENT HEAVY OBJECTS THAT MAY FALL ON YOU
3️⃣ DO NOT GET UP IF YOU ARE ON A BED PROTECT YOUR HEAD WITH PILLOWS
4️⃣ STAY INDOOR UNTIL SHAKING STOPS AND IT IS SAFE TO MOVE OUTSIDE MOST OF INJURIES OCCUR WHEN PEOPLE INSIDE THE BUILDING ATTEMPT TO MOVE TO A DIFFERENT LOCATION WITHIN THE BUILDING OR TRY TO RUN OUT OF THE BUILDING
Hope the answer will be helpful for you mate...
keep smiling always ☺️
