Explorers have detected a concealed fracture under the Marmara Sea where perilous pressure may accumulate. This zone is thought to be the probable focal point of a coming seismic event near Istanbul.

Researchers have located a hidden segment of the North Anatolian Fault underneath the Sea of Marmara, which investigators believe represents a prospective location for future significant earth movements. A recent investigation has demonstrated that alterations in the robustness of rocks within this area can initiate powerful shudders, which holds importance for the seismic protection of the locale, particularly the Istanbul vicinity.
This was documented by the SciTechDaily journal.
Turkey is situated at the nexus of several tectonic plates, and it’s this geodynamic intricacy that has consistently prompted ruinous seismic disturbances. Subsequent to the calamity in Erzincan in 1939, which resulted in over 30,000 fatalities, scientists have directed awareness to the pattern wherein potent earthquakes have transitioned westward along the North Anatolian Fault over time.
Numerous analysts regard the region beneath the Sea of Marmara as the most predictable spot—it hasn’t manifested substantial seismic activity for beyond 250 years, suggesting that stress has been accruing. Nevertheless, the fault’s precise architecture has protractedly persisted as obscure.
An assembly spearheaded by Dr. Yasuo Ogawa from the Tokyo Institute of Science has fashioned the initial exhaustive 3D representation of the region’s substratum utilizing magnetotelluric data from two dozen stations. This approach has empowered them to recreate the allocation of electrical resistivity at profundities of tens of kilometers, pinpointing the perimeters of feeble and “impeded” sectors of the crust.
The model unveiled strikingly divergent regions: weak, low-resistivity, fluid-inundated territories and robust, rigidly secured segments. The limits among them could signify the origination zones of a forthcoming catastrophic seismic upheaval.
According to Ogawa, the outcomes of the inquiry aid in a more meticulous determination of prospective epicenters of intense tremors and their conceivable magnitude, which is vitally crucial for the framework of projecting and alleviating the repercussions of natural catastrophes in Turkey.
As a notation, a depression in Earth’s magnetic domain has been unearthed beneath the veneer of Australia. Scientists deem it the key to novel geological revelations.
