Researchers have unveiled the first global map highlighting a unique category of rare earthquakes that occur deep within the Earth's mantle rather than the Earth's crust, which is the usual focus of seismic studies. This groundbreaking research indicates that while these deep earthquakes are spread across various regions globally, they are particularly concentrated in two major areas: the Himalayas in South Asia and the Bering Strait between Asia and North America, near the Arctic Circle. The finding was published in the journal Science on February 5, marking a significant advancement in geophysical research.

Unlike typical earthquakes that manifest through noticeable tremors on the surface and can lead to significant destruction, these mantle earthquakes are located at such depths that they are rarely felt by the populace and do not cause immediate damage at the surface. However, the scientific implications of these earthquakes are extensive, potentially leading to a deeper understanding of the mechanisms behind earthquake formation in general. Researchers hope that by studying these phenomena, they might improve risk assessment and forecasting capabilities for seismic events.

The study serves not only as a documentation of this rare geological phenomenon but also underscores the complexity of the Earth's internal processes. By mapping such rare events, scientists aim to link these deep-earth activities to broader seismic patterns, which may ultimately contribute to advancements in earthquake prediction and management, thereby enhancing safety protocols in earthquake-prone regions across the globe.
