Artificial reefs protect the coral reefs in Eilat

Researchers from Ben Gurion University followed divers in Eilat for 15 years and found that the placement of the artificial reef reduced the pressure of diving on the natural reef
A study predicts the extension of the Strait of Gibraltar subduction zone into the Atlantic Ocean, which could create an Atlantic Ring of Fire within about 20 million years. This research sheds light on the dynamic nature of ocean life cycles and the formation of new reduction zones, using advanced computational models. It offers new insights into the activity of the subduction zone in Gibraltar and its implications for seismic activity, emphasizing the importance of preparedness and studying the process of ocean contraction as a key process in the geological evolution of the Earth.

As the oceans close - a new study indicates that the Atlantic Ocean will "soon" enter its sunset phase

Research shows for the first time how direct invasion of mitigation zones can occur. The 3D computational model, driven by gravity, predicts that the subduction zone currently under the Strait of Gibraltar will spread further into the Atlantic Ocean and contribute to the creation of an Atlantic subduction system - a ring of fire similar to that existing in the Pacific Ocean

Earthquakes of this magnitude in the region are rare but not unexpected. Since 1900 there have been 9 earthquakes of magnitude 5 or higher within 500 km of the current earthquake location but none of them were magnitude 6 or higher

The destruction of the Nova Kakhovka dam came just as it seemed that Ukraine's counterattack was about to begin. It's probably not a coincidence. The operation was designed to engage the Ukrainian army in evacuating residents and block the possibility for Ukraine to liberate Crimea

Winds of climate change

For two decades, researchers have been trying to find a way to track a climate system that has a decisive influence on the location of rainforests and deserts on Earth. A new study solves the challenge and reveals the extent of the influence of humans

Plastic continues to dominate every good plot: new research reveals that the amount of microscopic plastic on the ocean floor has tripled in just 20 years. Moreover, the microplastic at the bottom of the sea almost did not crumble or break down even after decades

The American company Ocean-Based Climate Solutions has developed a pump system that will pump nutrients from a depth of 400 meters to the surface and allow the growth of tiny algae that will carry out the process of photosynthesis and absorb the carbon in the atmosphere, so that it will eventually sink to the bottom of the ocean

The earthquakes in Turkey and Syria were deadly because they occurred close to the ground

  • No comments
Two strong earthquakes within a few hours and the fact that there was no thick layer of soil that reduces the intensity of the earthquakes, in addition to the construction conditions, and the destruction of the infrastructure - especially in Syria. The time of the earthquake at 4:17 in the morning also contributed to the high death toll

The magnetic field in the remains of fires makes it possible to discover the real story behind the descriptions in the Bible

A multidisciplinary study was able to date 21 layers of destruction at 17 archaeological sites in the State of Israel, with the help of measuring the direction and strength of the Earth's magnetic field, as they were "recorded" at the time the sites were burned, and to examine how much the biblical stories about the Egyptian, Aramaic, and Assyrian conquest campaigns And the Babylonians against the kingdoms of Judah and Israel were accurate
