On the earth, the scientific community has written two words "earthquake" on every move of faults. Of course, this is not a completely equivalent theory. According to the current earthquake relationship, most scientists believe that the situation is related to the occurrence of earthquakes and plate movement, and also the individual geological changes.
According to the latest scientific research, through the analysis of the boundary of the lithosphere asthroid in the Dinarid Mountains, they found that the thickness of the rock layer in the area varies between 50 kilometers and 160 kilometers, forming a new geological structure with the thinning lithosphere zone, and the layer gaps present in previous tomography images.
Scientists said that under the central Dinaria area, they also discovered an abnormally thinned lithosphere between 50 kilometers and 70 kilometers in the area, which plays an important role in the interaction between the Dinaria area, Adriatic and the Eurasian lithosphere plates, and is very important for understanding the complex tectonic history of the central Mediterranean region.
Scientists have determined the boundaries between different tectonic domains in this region, and the degree of change between adjacent tectonic regions is high. Under the Dinarid Mountains in the northeast, the depth of the fault has thinned about 100 to 120 kilometers to the Adriatic Sea and the Pannonia Basin, respectively, and now it has become about 90 and 70 kilometers, respectively. They were all reduced by about 10 kilometers and 50 kilometers in the original fault area.
Scientists say that in the central region of Dinali (Lica region), we found an abnormally thin lithosphere with varying thickness between 50 and 70 kilometers and defined weak velocity gradients. Extending further south, the signal from monitoring is more obvious, and the lithosphere becomes thicker, with an average depth of about 90 kilometers. This change is indeed rare because the lithosphere and fault areas are fluctuating changes.
In the central part of the Dinarid Mountains, scientists observed that the results of the changes in the thin lithosphere may be related to the low seismic activity zone, and the changes in the seismic zone are exactly the same as this structure. The tomographic images show the gap between the plates in this area and the cracks in the plates, so the possibility of earthquakes cannot be ruled out in the future, and the size of the earthquake is unknown. The gaps now may also be caused by small seismic activities.
