Earth’s magnetic field reached G3 – Strong storm levels on September 30, driven by CME impacts and sustained southward IMF. The event was enhanced by seasonal Russell–McPherron geometry near equinox, increasing coupling efficiency. Storm strength has since eased to G2 and G1 as IMF weakened and Bz returned closer to neutral.
Region 4232 produced two CME-associated M-class flares on September 28 and 29, 2025 — an M6.4 at 08:43 UTC on September 28 and an M3.6 at 01:45 UTC today. Forecast calls for unsettled to isolated G1 – Minor geomagnetic storm conditions on September 29, with mostly quiet levels returning by October 1.
Tornadoes triggered by Typhoon Bualoi struck Kim Son District in Ninh Binh Province, Vietnam on September 29, 2025, killing at least 9 people and flattening homes. Bualoi made landfall earlier the same day in northern Vietnam, leaving at least 11 people dead, 17 missing, forcing the evacuation of more than 28 500 residents, and damaging nearly 1 400 ha (3 460 acres) of crops.
A rare stratospheric warming event is disrupting the Antarctic polar vortex in September 2025, with forecasts suggesting wetter southern Australia, drier eastern Australia, and a higher chance of abnormally hot days.
The Japan Meteorological Agency (JMA) raised the Alert Level for Meakandake volcano in Hokkaido, Japan, from 1 to 2 at 06:20 UTC (15:20 JST) on September 15, 2025, after an increase in seismicity near Ponmachineshiri Crater. From September 16 to 23, eruptive activity continued with 27–50 daily volcanic earthquakes, minor ashfall, and white steam-and-gas plumes rising 200–800 m (656–2 625 feet) above the crater rim. Access within 500 m (1 640 feet) of the crater remains restricted, affecting parts of Kushiro City and Ashoro Town.
A shallow earthquake registered by the USGS as M5.9 hit off the coast of Oregon at 06:45 UTC on September 26, 2025 (23:45 local time, September 25). The USGS is reporting a depth of 10 km (6.2 miles). EMSC is reporting the same magnitude and depth.
The interstellar object 3I/ATLAS showed no measurable non-gravitational acceleration between May and September 2025, implying a nucleus mass above 33 billion tons and a diameter larger than 5 km (3 miles), according to a study co-authored by Harvard Professor Avi Loeb and published on September 24.
A strong atmospheric river is forecast to shift southward along the British Columbia coast between September 26 and 29, 2025, bringing several low-pressure systems and periods of heavy rainfall to Vancouver Island and the South Coast. Forecasts suggest up to 100 mm (4 inches) of rain in west-facing coastal mountains, with persistent showers likely across the Lower Mainland.
Heavy to excessive rainfall from monsoon thunderstorms may bring isolated flash and urban flooding to the Desert Southwest into Sunday, September 28, 2025. A plume of anomalously high monsoonal moisture streaming northward on the eastern flank of a slow-moving upper-level low will fuel several rounds of widespread showers and thunderstorms, with greatest impacts expected across southeastern Arizona and southwestern New Mexico.
New activity/unrest was reported for 6 volcanoes from September 17 to 23, 2025. During the same period, ongoing activity was reported for 23 volcanoes.
