The month of March had passed calmly with only two seismic events, to which was added a third of moderate intensity.
Sinaloa. – After several days of calm regarding the registration of earthquakes in the state of Sinaloa, the population felt the ups and downs again with another event recorded during the last minutes of Thursday, March 10.
The epicenter was fixed by the National Seismological Service on land, 18 kilometers east of Eldorado, Sinaloa at 11:54 p.m. and the intensity was 3.7 degrees, classified as moderate.
This is the third event recorded in the month: the first 96 kilometers southwest of Los Mochis on the 3rd with a magnitude of 3.7; the second of 3.9 degrees on March 8, 137 kilometers northeast of El Fuerte and that of Thursday 10 was the third of 3.7 degrees in Eldorado.
So far in 2022, there are 37 tremors listed in Sinaloa, the most intense so far recorded on January 8, 113 kilometers southwest of Guasave with an intensity of 4.5 degrees.
There are 14 events that have exceeded the line of 4 degrees of intensity, and most have been in the northern zone in areas of the municipalities of Guasave and Ahome, and one in the port of Mazatlán.
An earthquake is a sudden breaking of rocks inside the Earth. This sudden release of energy spreads in the form of waves that cause the ground to move.
The magnitude of an earthquake is related to the energy released in the form of seismic waves that propagate through the ground.
To calculate this energy and determine the magnitude of an earthquake, mathematical calculations are made based on the records obtained by seismographs from different stations. In these records or seismograms, the maximum amplitude of the waves and the distance of the station from the epicenter are measured. These values are entered into a formula, thus obtaining the magnitude.
Remember that when a large earthquake occurs, the rocks near the rupture zone are subject to rearrangement. During this process, a series of earthquakes known as Aftershocks are generated in this area, which are of lesser magnitude and can occur minutes, days, and even years after the main event. The number of these aftershocks can range from a few earthquakes to hundreds of events.
