Stanford University researchers have created the first global map of rare continental mantle earthquakes.

About Continental Mantle Earthquakes

  • Mantle earthquakes occur far deeper, sometimes more than 80 km below the Mohorovičić discontinuity, unlike most earthquakes, which originate in the Earth’s crust at depths of around 10 to 29 kilometres.
    • The Mohorovičić discontinuity or “Moho”, separates the crust from the warm, semi-solid mantle that makes up most of the planet’s interior.
  • They do not cause serious shaking at the surface.
  • Mantle earthquakes offer a novel way to explore earthquake origins and the internal structure of Earth.

Global Energy Monitor (GEM) released a new analysis of the global pipeline of wind and utility-scale solar projects.

Key Highlights

  • Pipeline: The global wind and utility-scale solar pipeline reached a record 4.9 TW in 2025, marking an 11% year-on-year increase.
  • The G7 Gap: G7 nations account for only 11% of this prospective capacity, despite controlling 50% of the global wealth.
  • Operating solar and wind power capacity: China has passed 1.6 TW of operating wind and solar projects. India ranks third globally, with more than 163 GW of operating wind and solar capacity.
  • Solar Composition: Distributed solar now comprises 42% of global solar capacity, though deployment remains unevenly concentrated in a few key markets.
