Richter scale is used to measure the magnitude of an earthquake Two ways to save ourselves from lightning 1. Stay away from an isolated place. 2. Best way is to crouch down if we're in an open field.
The Richter scale is a way of measuring the strength or magnitude of earthquakes. It was developed by Charles Francis Richter and Beno Gutenberg in 19351. The scale is based on the logarithm of the amplitude of seismic waves recorded by seismographs1. The formula for calculating the Richter magnitude is: ML=log10A−log10A0(δ) where ML is the local magnitude, A is the maximum amplitude of the seismograph, A0 is a function of the distance from the epicenter, and is the epicentral distance of the station1. The Richter scale is logarithmic, which means that each increase of one unit corresponds to a tenfold increase in the amplitude of the waves. For example, an earthquake of magnitude 5.0 produces waves that are 10 times larger than those of an earthquake of magnitude 4.0. The energy released by an earthquake also increases exponentially with the magnitude. Each increase of 0.2 units corresponds to approximately a doubling of the energy released1. The Richter scale has no upper or lower limit, but most earthquakes have magnitudes between 0 and 10. Earthquakes with magnitudes greater than 4.5 can be detected by seismographs all over the world1. The effects of earthquakes vary depending on the magnitude, the depth, the location, and the geology of the area. The following table shows some typical effects of earthquakes of different magnitudes near the epicenter2: Magnitude Effects Less than 2.0 Microearthquakes, not felt, or felt rarely by sensitive people. 2.0-2.9 Minor, felt slightly by some people, no damage. 3.0-3.9 Often felt by people, but rarely causes damage. 4.0-4.9 Light, noticeable shaking of indoor objects, rattling noises, significant damage unlikely. 5.0-5.9 Moderate, can cause major damage to poorly constructed buildings, slight to moderate damage to well-built structures, felt by most people. 6.0-6.9 Strong, can be destructive in areas up to about 160 km (100 miles) across, damage to a moderate number of well-built structures in populated areas. 7.0-7.9
@@Kiwi_047 The paper used is known as - 'seismogram' The study of these waves is -'seismology' The sciencts who study seismology are known as seismologists
The energy or the magnitude of the earthquake is measured on an open ended Richter Scale. I understood this chapter very well. Thank you Thank you so much sir
A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.
The Richter scale-also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg-Richter scale-is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale.
This video is a lightning of education for all of us. 😅😊 Thank You So Much Dear ALOK SIR 😊😊 All the topics r explained in a very well manner.. Really thanku...😊😊
Sir can you please leave some questions at the end of video for reference and sample questions for practising 😊? That will help us , students and clear doubts from core
The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.
The instrument which measures the magnitude of earthquake is called Ritcher Scale Thank You Sir I Understood All And this was a very Good explanation ❤😊😊❤
Richter scale used for measuring the intensity of earthquake.The Richter scale measures the maximum amplitude of seismic waves as they reach seismographs The magnitude is expressed in absolute number, 0-10.The power of an earthquake is expressed in terms of magnitude on a scale called the Richer scale.❤❤❤😊
So niceee lecture my all concepts about this chapter got clear... thank you sir 🙏 And here is the answer of homework Richter scale- A scale used to express the power of earthquake in terms of magnitude is called Richter scale
1. Richter Scale is used to measure the scale of absolute 'Magnitude' of an earthquake based on the amount of seismic energy released. 2. Mercalli scale measures the 'Intensity' of an earthquake based on based on the amount of destruction caused.
a numerical scale for expressing the magnitude of an earthquake on the basis of seismograph oscillations. The more destructive earthquakes typically have magnitudes between about 5.5 and 8.9; it is a logarithmic scale and a difference of one represents an approximate thirtyfold difference in magnitude.
Richter scale is used to measure intensity of earthquake. Richter scale is also used to describe the magnitude of an earthquake. you ,alakh sir and pw are just great
