SWOT Satellite Captures Tsunami Wave After Kamchatka Quake
On July 30, 2025, the NASA–CNES SWOT satellite captured the leading edge of a tsunami wave in the Pacific, triggered by an 8.8 magnitude earthquake near Russia’s Kamchatka Peninsula. Recorded about 70 minutes after the quake, the wave measured 1.5 feet in open water but could grow to 30 feet at shore. SWOT’s advanced radar mapped the wave’s...

New Island Forms in Caspian Sea as Water Levels Drop, Russian Scientists Confirm
Russian scientists have verified the existence of a new island in the northern Caspian Sea, first spotted via satellite in late 2024. Located 30 km from Maly Zhemchuzhny Island, the islet appeared as sea levels reached historic lows due to climate change and tectonic shifts. Although researchers couldn’t land due to shallow water, drone images ...

Seismic Mystery Solved: NASA’s SWOT Satellite Detects Greenland Mega-Tsunamis
In September 2023, a global seismic mystery puzzled scientists for nine days. New research now confirms it was caused by two mega-tsunamis triggered by landslides in East Greenland. The waves became trapped in a fjord, forming seiches that shook the Earth. Using cutting-edge data from NASA’s SWOT satellite, scientists detected these hidden waves ...

Concerns Rise Over Atlantic Meridional Overturning Circulation Stability and Climate Impact
A new study suggests the Atlantic Meridional Overturning Circulation (AMOC) has remained stable over the past six decades, but experts remain divided. While some scientists argue the system has not weakened, others believe potential future disruptions to AMOC are inevitable, with major climate implications, including extreme weather events and cold...

World's Largest Iceberg A23a Resumes Journey North After Months of Stagnation
A23a, the largest iceberg in the world, has begun moving again after being trapped in a vortex near the South Orkney Islands. Weighing nearly a trillion tonnes and twice the size of Greater London, the iceberg has been stuck in the Weddell Sea for over three decades. Now on its way north, scientists are studying its potential environmental impacts,...
