The Colombian Geological Service reported a new earthquake of magnitude 4.4 on Thursday afternoon, September 7.
We tell you all the details about this subject new seismic event event occurring in the country.
According to the Geological Service bulletin, the earthquake occurred at around 03.53 in the morning. The epicenter was Santander, Los Santos.
Its intensity was 4.4This means that the earthquake is classified as a widely felt earthquake.
Depth was 148 kilometers and so far no damage has been reported.
It should not be forgotten that the high seismic activity in the country is due to the fact that Colombia is located in a region where various tectonic plates meet and due to this geological interaction, earthquakes occur in a large part of its territory.
The SGC uses a different measurement system than the Richter scale and the moment magnitude scale.
In fact, the measurement system they use is the European macroseismic scale, better known as EMS-98.
According to a report from the organization, this scale “expresses the distribution and intensity at which the earthquake is felt, taking into account the impacts reported by the population through the form for assessing intensities in different municipalities.”
So things are like this: The intensity of 4 points is defined as a “widely felt earthquake”.
This is the step by step way to manually activate the seismic alarm option on your mobile phone.
As explained by the Geological Service of Colombia (SGC),earthquake “danger”Earthquake magnitude, which expresses the potential effects that such an event can have in a particular region, depends on many factors such as the depth of the seismic focus, distance from the epicenter, local geology and population density in the region. the quality of the area as well as the buildings and infrastructure.
The term magnitude refers to the amount of energy released at the location where the earthquake occurs. Experts obtain this data after reviewing seismological records and define it on a clear scale, going up to 10.0 for earthquakes of tectonic origin. (it is a universal measurement).
(What should be done before, during and after an earthquake?).
Depth is the distance separating the place in the Earth where the earthquake occurs (source, epicenter or seismic focus) and the Earth’s surface (epicentre) where that energy is released.
This is measured in kilometers. “Earthquakes can be divided into three types depending on the depth of the epicenter: superficial, with a depth of 70 km, moderate, with a depth of 70 to 300 km, and deep, with a depth of more than 300 km.” SGC.
In this way, the effects that an earthquake can have on the infrastructure of a place and therefore on people depend, among other things, on the relationship between the magnitude and depth of the earthquake. “The greater the intensity and the shallower the depth, the greater the impact.. Therefore, it is very important to take depth into account when sizing the impact that an earthquake can have,” says the Colombian Geological Service.
