Global Meteor Airburst Activity in 2025

On a global scale, meteor airburst activity in 2025 has been comparatively subdued. While localized atmospheric disturbances and cetacean strandings have been documented, the overall frequency of events has declined markedly relative to preceding years. The distribution of activity suggests that the situation, although notable, could have been considerably more severe under different conditions.

The temporal pattern of activity during the current year has been irregular. Elevated activity was recorded at the start of the year, followed by a pronounced decrease. A subsequent short-lived resurgence occurred before levels once again diminished. Spatially, the most active regions have been Northern Europe and the west coast of North America. Of particular interest is a recent airburst detected over Japan, which remains under ongoing investigation. Additionally, an unresolved case off the west coast of northern Africa coincided with cetacean strandings, raising questions about possible atmospheric or geophysical interactions.

As of September 2025, a total of 23 confirmed airbursts have been recorded worldwide. This figure falls below the long-term mean annual frequency of approximately 33 events. Fireball activity has also been comparatively limited, although several highly luminous events (“wow” events) have been observed. The progression of activity in the final four months of 2025 will be critical in determining whether the year’s total aligns with or diverges significantly from the established climatology of meteor airbursts.

In addition, Western Australia has experienced a notable outburst. This region, however, has historically exhibited persistent activity and continues to display a relatively stable background frequency of events.

Third airburst in Mexico region Updated 20250604

An airburst over land in Mexico brings the tally to three in just over 6 months. The cumulative energy released is 6.8 kt or 6,800,000 kg/TNT. The other two occurred over the Pacific Ocean. This meteor activity has profoundly affected cetacean activity in the region, with its ramifications felt north along the USA west coast. 

2025, May 31. Mexico, Hidalgo State, Xiliapa. Airburst. Coordinates: (98.8 W, 21.1 N). Time: 23:06. Energy: e = 38.6, -e = 1 or 1,000,000 kg/TNT. Altitude: 47.3 km. Velocity: 17.8 km/sec.  

Also: 

2025, May 29. USA, Oregon, Cachalot (sperm whale). Adult male, measured approximately 53 ft long. Cause of death: It appears to have been due to a pre-mortem vessel strike interaction.

2025, June 1. UK, Cleethorpes. Dead dolphin.

2025, June 1. UK, Cleveleys beach. A dead porpoise. It’s the latest porpoise to wash up on a Fylde coast beach in recent months, with others discovered on beaches in Fleetwood and Blackpool.

2025, June 2. USA, Massachusetts, Cape Cod Bay. Fireball. Time: 20:07EDT Seen in Connecticut, Maine, New Hampshire, New Jersey and Rhode Island. A Marine Animal Disturbance Alert should be noted for this region due to historical data showing it as a cetacean stranding hotspot. Update: Cancel Alert due to information suggesting this event was above the inland coast, not water.

Large Long Duration Fireball in Fiji

2025, May 23. Fiji. Large Fireball. Duration: +1m. Fijians witnessed a fast-moving meteor. Fiji Met said it was debris from Halley's Comet.
