Definition of Earthquake

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. People can scale seismic waves as The Richter scale.

Definition of the Richter Scale

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 was later revised and renamed the local magnitude scale, denoted as $ML$ or $M_{L}$.

$$M_{L} = log_{10} A - log_{10} A_{0}(δ) = log_{10} [A/A_{0}(δ)]$$

$A$ is the maximum excursion of the Wood–Anderson seismograph

The empirical function $A_{0}$ depends only on the epicentral distance of the station, $δ$. In practice, readings from all observing stations are averaged after adjustment with station-specific corrections to obtain the $M_{L}$ value.

Kandilli Observatory and Earthquake Research Instıtute (KOERI)

Kandilli Observatory and Earthquake Research Instıtute (KOERI) determines the location and size of all earthquakes that occur in Turkey and disseminates this information immediately to national and international agencies, scientists, critical facilities, and the general public. This project was created based on data obtained by the Kandilli Observatory and Earthquake Research Instıtute (KOERI).

Donate For Disasters

Turkey has recently been struck by a devastating earthquake with a magnitude of 7.8. The impact has been widespread and many communities have been severely affected. In this difficult time, we are reaching out to ask for your support. Any donation, no matter how small, will help us provide much-needed aid to those affected by the earthquake. Your generosity will help provide shelter, food, and medical supplies to those in need. If you would like to make a donation, at the buttom we shared IBAN information for contribution. Your contribution will make a real difference in the lives of those affected by this disaster. Thank you for your kindness and support.
