What is the story about?
What's Happening?
Researchers from the University of Cambridge have uncovered the reasons behind extensive volcanic activity in the North Atlantic region 60 million years ago. The study reveals that variations in the thickness of tectonic plates allowed the Icelandic mantle plume to spread molten rock over a vast area, affecting regions from Scotland to Greenland. This discovery was made using seismic tomography and thermography, which provided insights into the Earth's interior structure and temperature variations. The findings help explain the distribution of ancient volcanoes and their impact on the region's geological history.
Why It's Important?
Understanding the behavior of mantle plumes and their influence on volcanic activity is crucial for comprehending Earth's geological processes. This research not only sheds light on historical volcanic events but also has implications for current seismic hazards and geothermal energy potential. By mapping the thickness of tectonic plates, scientists can better predict areas susceptible to volcanic activity and assess geothermal resources. This knowledge is valuable for energy exploration and managing natural disaster risks, particularly in regions with thin lithosphere where volcanic activity is more likely.
