A strong earthquake registered by the USGS as M6.0 hit near the east coast of Honshu, Japan, at 15:21 UTC on October 4, 2025 (00:21 LT, October 5). The agency is reporting a depth of 46.8 km (29 miles). EMSC is reporting M6.0 at a depth of 47 km.
A strong earthquake registered by the USGS as M6.1 hit off the east coast of Kamchatka, Russia at 16:07 UTC on October 3, 2025. The agency is reporting a depth of 17.4 km (10.8 miles). EMSC is reporting the same magnitude and depth.
A major flood hit the Elenite holiday village on Bulgaria’s Black Sea coast at around 11:40 LT on October 3, 2025, after 200–250 mm (7.9–9.8 inches) of rain fell in a short period. Environment Minister Manol Genov described the rainfall as among the most intense recorded in the region in recent years. At least three people died, and six women, including three Polish tourists, were rescued.
A mud volcano at Jarawa Creek, Baratang Island, Andaman and Nicobar Islands, erupted at around 11:00 LT (05:30 UTC) on October 2, 2025, after lying dormant for two decades. The eruption released mud, gases, and water across more than 1 000 m2 (10 760 ft2), forming a mound about 3–4 m (10–13 feet) high.
Storm Amy is forecast to bring hurricane-force winds to Ireland and the UK on October 3, 2025, with Met Office amber warnings and Met Éireann red marine warnings in effect.
A previously unknown meteor shower, the gamma-Horologii, was detected in the southern hemisphere between September 15 and 26, 2025. The outburst is ongoing, with the radiant located near the star gamma Horologii.
A newly-discovered asteroid designated 2025 TF made an extremely close approach to Earth at 00:49 UTC on October 1, 2025, reaching a nominal distance of 0.02 LD (0.00005 AU / 6 790 km / 4 220 miles) from Earth’s center — equivalent to about 419 km (260 miles) above the surface over Antarctica. At this distance, it is now classified as the second-closest asteroid flyby ever recorded.
New activity/unrest was reported for two volcanoes from September 24–30, 2025. During the same period, ongoing activity was reported for 22 volcanoes.
A G3 (Strong) geomagnetic storm is in progress on October 2, 2025, driven by a positive-polarity coronal hole high-speed stream (CH HSS). The U.S. Space Weather Prediction Center (SWPC) issued an active warning valid until 12:00 UTC, with aurora sightings possible as far south as Pennsylvania, Iowa, and Oregon.
Episode 34 of the ongoing Kīlauea eruption ended at 07:03 HST (17:03 UTC) on October 1, 2025, after 6 hours of lava fountaining from two vents in Halemaʻumaʻu crater at the volcano’s summit, Hawaii. Lava fountains reached up to 400 m (1 300 feet), erupting about 9 million m³ of lava at a peak effusion rate of 500 yd³/s. The eruption filled much of the western crater floor before activity ceased.
