Recent research has provided a deeper understanding of the mysterious craters appearing in Siberia. These craters, some as deep as 160 feet (50 meters) and wide as 230 feet (70 meters), form when thawing permafrost triggers sudden methane gas explosions. The permafrost thaw causes cracks, releasing methane gas stored deep underground, leading to these dramatic explosions.

Unique Geological Conditions in Northern Russia

According to Ana Morgado, a doctoral student and chemical engineer at the University of Cambridge, this phenomenon is extremely rare and specific to the Yamal and Gydan peninsulas in northern Russia. Cryopegs, which are ancient salty water pockets, exist only in this region, and they play a crucial role in the process.

Pressure Build-up and Explosions

Cryopegs, which were formed from prehistoric seas that existed during the last ice age, stay liquid despite freezing temperatures due to high pressure and salt content. As meltwater from thawing surface permafrost seeps into these cryopegs, the pressure builds up over decades. Eventually, cracks form in the permafrost, releasing the pressure and causing methane hydrates to decompose into gas, triggering an explosion.

Implications for Global Warming

Though the phenomenon is rare, the release of methane gas during these explosions could have a considerable impact on global warming. Methane is a powerful greenhouse gas, and its release could trigger further environmental concerns in the Arctic regions. These craters, which only appear in northern Russia, offer new insights into the complexities of permafrost thawing and its potential consequences for the climate.

Rocket Lab reached a key milestone with its 70th Electron rocket launch, successfully sending five secret satellites into orbit on Aug. 23, 2025. The mission, called “Live, Laugh, Launch,” lifted off from New Zealand and ended its live stream early at the request of the undisclosed customer. Rocket Lab now looks ahead to the debut of its larger Neutron rocket late…

Researcher Photographs Giant Solar Tornado and Massive Plasma Eruption at the Same Time

Published

On August 20, researcher Maximilian Teodorescu captured a rare photo of two dramatic solar events — a giant tornado of plasma rising 130,000 km and an eruptive prominence spanning 200,000 km. Both were shaped by the sun’s unstable magnetic fields. While the prominence did release a CME, it is not aimed at Earth.
