Richter Scale Day 2024 is on Friday, April 26, 2024: The richter scale? 10 points five stars?
Friday, April 26, 2024 is Richter Scale Day 2024. What is the Richter scale What is the Richter scale
If there’s ever each day to carry onto hats, double-test fundamentals and an ear out for rumblings deep inside the Earth, it’s Richter Scale Day. This occasion is definitely an acknowledgement and celebration from the birthday from the guy who trained the planet how you can measure earthquakes – Charles F. Richter.Born in 1900, the American earthquake obsessive (technically referred to as a ‘seismologist’), emerged using the Richter Scale in 1935, while in the California Institute of Technology. Since that time, the earth has had the ability to compare various earthquakes and investigate their relative energy for destruction. The Twentieth century’s greatest happened in Chile on 22 May 1960, calculating a magnitude of 9.5.Many people celebrate by reaching a lot of buddies to look at their favourite disaster films. 1974′s Earthquake, 1999′s Aftershock: Earthquake in New York and 2003′s The Core are preferred options.
Richter Magnitudes Description Earthquake Effects Frequency of Occurrence
Less than 2.0 Micro Microearthquakes, not felt. About 8,000 per day
2.0-2.9 Minor Generally not felt, but recorded. About 1,000 per day
3.0-3.9 Minor Often felt, but rarely causes damage. 49,000 per year (est.)
4.0-4.9 Light Noticeable shaking of indoor items, rattling noises. Significant damage unlikely. 6,200 per year (est.)
5.0-5.9 Moderate Can cause major damage to poorly constructed buildings over small regions. At most slight damage to well-designed buildings. 800 per year
6.0-6.9 Strong Can be destructive in areas up to about 100 miles across in populated areas. 120 per year
7.0-7.9 Major Can cause serious damage over larger areas. 18 per year
8.0-8.9 Great Can cause serious damage in areas several hundred miles across. 1 per year
9.0-9.9 Great Devastating in areas several thousand miles across. 1 per 20 years
10.0+ Great Never recorded; see below for equivalent seismic energy yield. Extremely rare (Unknown)
Help with the richter scale?
Richter scale energy release increases by 31.7 times for each Richter scale. But the damages are caused by the amount of shaking's.The amplitude increases by 10 times for each Richter scale. The shaking reduced as the distance increases from epicenter in the order of inverse square of distance. The energy release for fraction of Richter scale needs some complicated calculation. However I am giving you the formula and energy release chart. For each one whole number it is 31.7 time. Calculation of Richter scale.
For body wave
mb = log V p-wave +0.01delta+5.1
For surface wave
Ms = log V surface-wave + 1.66log delta+2.5
where V is the velocity of the wave in micrometers/sec, and (Delta) is the angular epicentral distance in degrees.

For 0.1 increase the stronger will be about 3 times .
Earthquake Richter scale estimates. Why so different from country to country?
The Richter scale is the measure of the energy released from the origin point called focus. Mr. Charles Richter found a method by knowing the distance of seismic recording station and the maximum amplitude recorded can be used to estimate the Richter scale. There are several factors deciding the data’s collected by various seismic stations. There are several scales within Richter scale like Ms,Mb,Mw using various methods. According the circumstances different methods gives fairly correct result. The geological condition of the places through which the seismic wave travels gives different data’s. Therefore there are possibilities of giving different measurement from different stations. But theoretically it should not differ. The correct result can be decided after averaging the results obtained from more number of stations. That is why even the USGS gives first one measurement and again after it will be revised by seismologist’s .The Boxing Day earthquake that created the Tsunami was first reported by our meteorological department as 7.6 in Richter scale. After few hours it was reported by USGS as 8.7 .After 3 months it was reported as 9.3. But with the use of my simple earthquake alarm I have cautioned our local T.V.Stations as "I have sensed very big earthquake which I never heard in the history of earthquake and I have also cautioned them about possible Tsunami attack.” Instead of appreciation I was only criticized for my dedicated service of designing the life saving equipments that proved its capability on the day of Tsunami.
