A massive landslide released at least 12 000 m3 (424 000 ft3) of rock from 1 300 m (4 265 feet) altitude at Cirque du Fer-à-Cheval in Sixt-Fer-à-Cheval, Haute-Savoie, France, at 11:30 LT (09:30 UTC) on September 6, 2025. Expert analysis suggests the actual volume may reach 30 000–40 000 m3 (1.1–1.4 million ft3), making the event exceptional for this sector.
Indonesia’s Geological Agency raised the alert status of Mount Lewotobi Laki-laki in East Flores to Level IV (Awas) at 10:00 WITA on September 6, 2025, due to increased seismicity, continuous tremor, and deformation indicating shallow magma ascent.
A large filament eruption was observed at 19:45 UTC on September 4, 2025, followed by at least three CMEs. Model runs suggest a likely arrival early on September 7. In addition, a recurrent positive polarity coronal hole high-speed stream (CH HSS) activity is expected to enhance solar wind parameters beginning early September 6, with G1 – Minor to G2 – Moderate geomagnetic storm conditions likely through September 8.
New activity/unrest was reported for 6 volcanoes from August 27 to September 2, 2025. During the same period, ongoing activity was reported for 23 volcanoes.
Hurricane Kiko remains a strong category 3 system with maximum sustained winds of 205 km/h (125 mph), moving west at 15 km/h (9 mph). Swells from the storm are expected to reach the Hawaiian Islands late this weekend, producing life-threatening surf and rip currents.
Around 6 to 7 million m3 (212 to 247 million ft3) of magma have accumulated beneath Svartsengi, Iceland since the eruption on July 16, 2025. At the current rate of accumulation, the estimated threshold of 12 million m3 (424 million ft3) could be reached in the latter half of September, increasing the likelihood of a new eruption.
A moderate earthquake registered by the USGS as M5.9 hit the Chile–Argentina border region at 04:10 UTC on September 4, 2025. The agency reported a depth of 176 km (109 miles). EMSC is reporting the same magnitude and depth.
A shallow earthquake registered by the USGS as M6.0 hit Fox Islands, Aleutian Islands, Alaska at 20:57 UTC on September 3, 2025. The agency is reporting a depth of 10 km (6.2 miles).
A strong cold front is sweeping southeast across the Great Lakes, Upper Midwest, and central Plains on September 3, 2025, bringing temperatures up to 25°C (45°F) below seasonal averages and triggering strong to severe thunderstorms.
A newly discovered asteroid designated 2025 QD8 will fly past Earth at a distance of 0.5 LD (0.00146 AU / 218 351 km / 135 677 miles) from the center of our planet at 14:58 UTC on September 3, 2025.
