Cachalot dead in Indonesia

2026, September 8. Indonesia, North Maluk (Molucca Sea), Ternate Island, Afe-Taduma Beach. The carcass of a female cachalot (sperm whale) found stranded. The whale had a total length of 9.8 meters, a body girth of 6.6 meters, a pectoral fin length of 75 centimeters, a dorsal fin length of 40 centimeters, and a tail length of 2.8 meters. Due to its size, an excavator was used to move and bury the carcass. Burial occurred near the stranding site to allow ongoing monitoring and ensure safe decomposition without environmental impact. See post below on meteor.

I've placed an approximate line over North Sulawesi where sound reports of the meteor were received after the September 12th meteor explosion (see post below). In the north of Sulawesi, there was a strong electrophonic signature. To the west of the island, there was a delayed sonic boom. The stranding occurred to the east across the Molucca Sea. 

Another whale stranding in Papua New Guinea

2026, September 10. Papua New Guinea, Raicoast, Madang Province. A large cachalot (sperm whale) washed ashore dead in a moderate state of decomposition. Cetacean strandings in this region have risen, as documented in previous posts. The tally includes two sperm whales, pilot whales and beaked whales. 

Blue whales strange behavior and cachalot stranding

I've been watching the tropical north, as written in previous posts, due to meteor activity and other natural phenomena taking place, and came across a standing and a near-stranding event. 

2026, September 8. Indonesia, North Maluku, Ternate, Kelurahan Afe Taduma Beach. A cachalot, sperm whale (Physeter macrocephalus), stranded. The sperm whale, approximately 9.8 meters long, apparently died before beaching. It was spotted by fishermen two days prior. 

2026, August 2. Indonesia, West Papua, southern Cenderawasih Bay, Kwatisore. A circular hole/depression in the reef measuring approximately 100 meters in diameter and 12 meters deep in the middle, accessible via a narrow, shallow channel. First recorded sighting of a blue whale (Balaenoptera musculus) inside Cenderawasih Bay. The initial observation took place on August 2nd. Two whales approached within 200 meters of the shore. The larger whale entered the narrow reef channel and into the circular hole, while the smaller whale turned around and left the area. The entrapment phase lasted from the 2 August to approximately the 21 August. The blue whale (~20 meters in length) remained localised within the shallow 100 m reef hole for nearly three weeks. The animal swam in tight, continuous circles due to spatial constraints but exhibited calm behaviour. Attempted herding/rescue operations using surface dinghies to guide the whale back through the shallow exit channel were unsuccessful, as the whale refused to approach the channel. Sometime around the 21st of August, the whale successfully navigated out of the reef hole and channel on its own and departed the area. Local reports indicate three previous similar entrapment events at this exact reef location occurring more than 15 years prior, showing a recurring pattern. Three black dolphins died here before in a mass stranding years prior.

The 1950 Meteor Airburst and following Cetacean Deaths

1950, June 21. Australia, Tasmania. Meteor Airburst. Called the “Tasmanian Incident”. Time: Approximately 12:15 AM to 12:30 AM. Described as a violent event. This was a rare, slow-moving bolide that traveled from the NW to the SE, exploding over the Tasman Sea. Reports note that residents as far away as Launceston and the Huon Valley felt the "violent" rattle, over 170km apart. Duration: Witnesses described a slow-moving, brilliant object that took nearly one minute to cross the sky. This long duration suggests a very shallow entry angle (an "earth-grazer"), which allows the shockwave to be distributed over a massive horizontal distance rather than a single point. As it moved toward the Tasman Sea, it culminated in what was described as a "violent explosion" or series of detonations. Residents across Tasmania—from Hobart to the north coast—were jolted awake. Many reported the rattling of windows and a low-frequency rumble that lasted for several seconds after the visual flash had disappeared. Marine Impact High (Acoustic coupling with water).

1950, July 3 (Reported). Tasmania. A 50ft. A dead whale floating bottom up caused a wreck scare. People who saw it about three miles-off Lisdillon.

1950, July 4. Tasmania, Iron Pot / Derwent. 2 Cachalots (Sperm Whales) seen "disoriented" and "unresponsive." Witnesses stated they were "milling aimlessly" near the Iron Pot lighthouse at the entrance to the Derwent. They noted they seemed unresponsive to the noise of passing fishing vessels—a classic sign of acoustic nerve deafness.

1950, July 9. Tasmania, Tasman Peninsula (near Safety Cove/Port Arthur area). A Beaked Whale live-stranded; appeared "exhausted." This date is critical because it represents the "final exhaustion" phase. The animal likely spent the weeks since the June 21 burst unable to dive or feed due to balance (vestibular) failure caused by the airburst's pressure wave. It reportedly made no effort to return to the water even as the tide rose, suggesting total vestibular (balance) failure.

1950, July 15. Tasmania, South Arm. Reports of "large carcasses" seen floating offshore.  

Mass Cachalot stranding in Denmark

2026, February 20. Denmark, at Skallingen near Fanø. A mass stranding of 4 cachlots (sperm whales). The next day another two stranded. At the same time, there were observations of live animals in the sea off the coast. Previous stranding and meteor activity are covered in a previous post. It's not as complex and energy-driven as the 2016 incidents; however, this could be the start of something that could escalate. Hopefully it won't. In 2016 a large meteor fell over Denmark, the big event (Ejby Meteorite Fal). The fireball’s path moved from the southwest to the northeast, passing over the German-Danish border and terminating over the Zealand region of Denmark. As of February 20, fireball activity has remained steady. When these cluster strandings occur, there is very often a significant meteor event that occurs pre, post, or in the middle. The other note is that the current strandings are occurring at a higher latitude, and the UK and France have had none. I'm currently cross-referencing 2016-2026 and any activity in Norway. See February 7th post.

Update: 20260221: 

2026, January 4. Denmark, Fireball. on Sunday, January 4th 2026 around 22:35 UT. 2026-01-04 23:35CET. Seen in Denmark and Friesland - Netherlands.  

2026, January 14. Netherlands, North Sea. Fireball. Flevoland, Friesland, Gelderland, Noord-Holland, North Holland, Overijssel, South Holland, Utrecht and Zuid-Holland. Time: around 17:59 UT. 2026-01-14 18:59CET. Travelling SW off the coast in the North Sea.

February 18. Denmark, Fireball. Travelling NE. Time: around 17:06 UT. 18:06CET. Seen in Östergötlands län, Halland County, Mecklenburg-Vorpommern, Niedersachsen and Schleswig-Holstein (Sweden, and Germany).

2026, February 18. Denmark, Fireball. Travelling west. Time: 22:54UTC. Velocity: 67.97 km/s. Duration: 2.09 seconds over 140km. Altitude: 118 to 106km. The track occurred 50km north of the stranding.  

2026, January 20. Denmark. Fireball. Travelling NNW over Zealand. Time: around 22:33 UT. 2026-01-20 23:33CET Seen in Sachsen-Anhalt, Schleswig-Holstein, Skåne County and Skåne län (Sweden, and Germany).

I will post further developments as they come in. The risk of further stranding is high. Note: There are no active seismic surveys currently underway in the North Sea.

Update 20260222: Another two sperm whales have come ashore, bringing the total to six. They are a juvenile bull bachelor pod. This brings the total of eight sperm whales dead in Denmark.

Two cachalots (sperm whales) dead in Denmark

2026, January 31. Denmark, Ålbæk Bugt, south of Skagen. A 13.7-meter-long cachalot (Sperm whale) stranded and died. Necropsy: The whale appeared to be in relatively good physical condition (not emaciated), suggesting it had been feeding until recently and was not suffering from long-term starvation caused by a "ball" of plastic or netting. I have posted before about cetaceans becoming scavengers in shallow rather than deeper water when they are no longer able to feed. Three fireballs of note: One occurred on the 4th and the other on the 20th. Both produced sonic booms. The first was seen in Friesland and the second in Sachsen-Anhalt, Schleswig-Holstein, Skåne County, Skåne län. Another (not shown on map below) on January 14th was over the North Sea, north of the Netherlands, however no reports of sound were made. It was a relatively large, some distance from the coast, and lasted for a considerable duration. I'm currently working on this post regarding the collection of further fireball data and necropsy results. There was a large event in the North Sea in December, and I will update.

2026, February 6. Denmark, Region Esjberg, Blåvand (on North Sea side),sandbank off Blåvandshuk Lighthouse. Another dead cachalot (sperm whale) found stranded and dead.

Cachalot dead in Spain

2025, December 27. Spain, Costa Brava, Platja d'Aro beach. A Cachalot (sperm whale) calf washed ashore dead after a days-long levanter storm. The tether line dragged the cetacean to shore. 

2025, December 27. Malaysia, Borneo, beach in Karambunai. Dolphin stranded prompted investigations by the relevant authorities, with officials confirming that a report has been received.

Satellite image of dead whale and the prevention of whale strandings

Canada, Newfoundland, Clay Cove. Looks like a Sperm whale carcass floating near shore at 49°43'42.9"N, 56°41'21.8"W. Real-time satellite images could really change how we deal with whale strandings and prevention. Could you imagine AI tracking pods sending an alarm when one is close to shore?

Attempted/ongoing stranding attempt and dead cachalot on Chatham Island east of New Zealand

2025, November 4. Chatham Islands (Rēkohu). Near Stranding. Two large groups of Black Dolphins (Pilot whales) surrounded by a smaller species of dolphin. Pilot whales were mustered out of the bay by a boat. The whales were head bobbing which is a sign of stress.

Also on the same island: 2025, November 3. Chatham Islands. A 50 ft female Cachalot (Sperm Whale) stranded and died on the other side of the island. It died in the early hours of the 4th. 

Update 20251109: So far, no pods have been seen near the shore. Good sign.

Because of the US Government shutdown, the information below is incomplete. I few bolides were detected after the July period; however, I assume there are more.

The Lebanon/Palestine mass cetacean stranding incident in 2023

2023, August 21. Cyprus, Mediterranean Sea. Fireball. Travelling east. Delivered concurrent and delayed sound. Time: Around 18:23 UT or 21:23LT. Seen in Antalya, Jerusalem District, Larnaca, Limassol, Nicosia, Paphos. This was the only event recorded in the region that created a sonic boom in 2023 and three years before this. The last one recorded was out of the cetacean migratory season. 

2023, August 28 to September 3. Israel and Lebanon. A cluster stranding of 3 cachalots (sperm whales). The first of the three was found August 28, on a Palestinian beach. The carcass of a male sperm whale was ~ 12 meters long. The second washed up the next day, August 29, north of the city of Tyre in Lebanon was ~ 14 meters long. The third was found on Sunday, which given the date sequence would be September 3, (assuming that timeline) south of Tyre. It was a male sperm whale. The size less clearly given in that report. Researchers noted the unusually close timing and location: three whales in a short stretch of coastline (~130 km) between Israel and Lebanon. At least two of them were male. Because sperm whales often travel in groups of young males (“bachelor groups”), this raised concern that some traumatic regional event (e.g. seismic activity or underwater blast) might have affected the group.  

Mass whale stranding in Canada

2025, September 27. Canada, Prince Edward Island, Pituamkek National Park Reserve. Efforts are underway to refloat three large sperm whales that are stranded off western Prince Edward Island's North Shore. The cetaceans stranded on the ocean side of a small chain of islands close to Hardys Channel on Gulf of St. Lawrence side, near East Bideford. Meteor activity in the region includes an event on the 21st west of Quebec City and one on the 22nd on the east coast of Nova Scotia, with both events producing sonic booms.

Note: (Southern Hemisphere) There is an active meteor outburst in the constellation of horologium. Next 72 hours. The radiant is near Gamma Horologii.  

Cachalot calf dies in Samos

2025, August 31. Greece, island of Samos, North Aegean. Dead cachalot (sperm whale) calf. There was a sonic boom heard in Istanbul and the Aegean Sea region on August 2nd, with the object seen as far south as Crete The second fireball was over the north Thracian Sea coastal area on 20th. Information is limited. The August 2nd event was travelling towards the Black Sea. 

Update: 2025, August 1. Aegean Sea. Fireball. Travelling north. 2025 around 20:27 UT. Local Time: 23:27EEST.

Update 20250902: Another Fireball: Saturday, August 30th 2025, around 18:14 UT. Over the coastal region of Izmir in Turkey, the east Aegean Sea. Reports from Greece and Bulgaria. Traveling east.

Update 20250905: Mediterranean, Ionian Sea. Fireball. Travelling NNW towards the Adriatic Sea. No Sound. Seen in Sicilia and Vlorë County on Tuesday, September 2nd 2025, around 17:59 UT. Local Time: 20:29.

This is not a mass stranding event, however there is a lot of activity in the region, so it could escalate. 

Japan cetacean strandings

There will be further data added to list. 

2025, August 19. Japan, Hokkaido, Urahoro. Species Name: Cachalot. Sperm whale (Physeter macrocephalus). Coordinates: Long-Lat: (42.829063N 143.849480E). In a state of advanced decomposition. Body length: ~10m. Sex: Unknown.

2025, August 20. Japan, Hokkaido Hidaka. Species Name: Short-finned pilot whale (Globicephala macrorhynchus). Coordinates: (Long-Lat: 42.468305N 142.120956E). In a state of advanced decomposition. Body length: 573.5. Sex: M

2025, August 25. Japan, Hokkaido, Tomakomai. Species: Short-finned pilot whale (Globicephala macrorhynchus). Coordinates: (42.602420N 141.493814E). In a state of moderate decomposition. Body length: ~2m. Sex: Unknown.

Another fireball west of Baja California, Mexico

2025, June 16. Mexico, Pacific Baja California Region. Fireball. Time: 22:00PDT, around 05:00 UT. Travelling NE. A Marine Animal Disturbance Alert is still in place for the Mexican and USA Pacific coastlines. With now 25 whale deaths in California since January, there could be a spike in cetacean casualties post this event.

Also: 2025, June 17. USA, Florida, Miami Dade. A 13-foot-long juvenile cachalot (sperm whale) was humanely euthanised after stranding. The individual will undergo a necropsy at NOAA’s lab in Miami to help determine cause of death. The only fireball in the Florida region in the last 49 days was a small fireball that dispersed no delayed or concurrent sound. There was a large one on the 29^th of April; however, its trajectory was mostly over land and north near Orlando. So, to wrap up, we have one fireball sighting and one stranding. 

The vast majority of the event below also occurred over land; however, I do take note of these for research purposes.

2025, June 15. New Zealand, North Island. Meteor. Time: 13:41. Direction: SSW. Velocity: 51 km/s. Duration: 6.39 sec. Coordinates: Beg: (-37.24, 176.14), End: ( -39.85, 174.58). Height: (113.73, 104.48km). Connected Shower: June rho Cygnids. Distance: 320 km.  

Whale dies in English Channel after two Fireballs

2025, May 22. English Channel. Fireball. Time: 22:01 UT;2025-05-23 00:01CEST. Almost identical to the event below, two days later, just further out into the sea. Seen in France and the Netherlands.  

2025, May 24. Bangladesh, Cox's Bazar sea. A 50-kilogram Irrawaddy dolphin was rescued.

2025, May 24. USA, California, New Brighton State Beach. Dead dolphin.

2025, May 24. English Channel. Fireball. Observed in France, Belgium, Germany, UK and the Netherlands. A sonic boom with concurrent and delayed properties was observed. Travelling SW over the mouth of the River Somme. 2025-05-24 Time: 00:00 or 22:03 UT May 23rd.  

2025, May 24.  English Channel, Guernsey, Channel Islands, Chouet Beach. Dead whale.

2025, May 24. South Africa, Struisbaai on the plaat. A cachalot (sperm whale) washed ashore alive but died. There have been two meteor airbursts within regional stranding parameters, one on March 29 and the other on April 8. See April 1st and April 9th posts regarding Marine Animal Disturbance Alerts. 

Sperm Whale in South Africa. 

Pulse Strandings in Germany after Meteor Activity

2025, May 12. Germany, Schleswig-Holstein, St. Peter-Ording. A Humpback whale 10 meters long, and the cause of its death is still unknown. This is the third stranding in the region. A 14-meter cachalot (sperm whale) was found on the island of Sylt, and then a younger and emaciated humpback whale was found on the island of Minzener-Oog. In February 2024 there was a pulse of strandings that came after fireball activity. This has played out the same way as in Denmark and Norway.

1967 Mass Sperm Whale Stranding in the Philippines

1967, May 7. Philippines, Negros Occidental, Cadiz City. A split mass stranding of 12 Cachalots (Sperm whales). The group of whales, one measuring 40ft long and 8ft. in height stranded in two groups, five days apart. Thus, the birth of the term Dinagsab, from a Hiligaynon word dagsa, which means to “gather”, “come together”, “driftage” or “to come in groups”, was made. The event gave Cadiz City the title City of Whales, the official seal of the City, and the former Ati Atihan Festival to be known as Dinagsa Festival in 2002. Cadiz locals viewed this event as a positive sign of fortune and prosperity from above.

Cetacean strandings since April 17

 2025, April 17. USA, California, San Diego, Nahant Court in Mission Beach. A dead dolphin.

2025, April 17? UK, Anglesey, beach near Rhosneigr (Porth Tyn Tywyn). Dead bottlenose dolphin.

2025, April 19. USA, Washington, near Cape Disappointment, Ilwaco, Long Beach, about four miles north of Seaview. A female dead gray whale. The whale was the fifth reported dead in Washington so far this year. Note: Two dead whales washed up along the Oregon coast last spring, and three others washed up in the span of a week in January 2023. Two of those five were also gray whales; the other three were a fin whale, a humpback whale and a sperm whale.

2025, April 17. Cambodia, Kampot province, Trery Koh commune. A pink dolphin ws found dead off shore. It weighed about 50kg and was 1.98 meters long.

The stranding team from NOAA Fisheries’ Southwest Fisheries Science Center recovered 16 dead dolphins from San Diego beaches on Sunday, April 20. These deaths add to the likely toll of a domoic acid outbreak produced by a harmful algae bloom off Southern California. Note: As of 27th April deaths continue.

2025, April 21. Philippines, Lianga Bay, Surigao del Sur, coast of Brgy. A stranded cetacean was identified as a Longman’s beaked whale.

Further cetacean strandings

Added whale strandings, with others catalogued at a later date.

2025, March 22. Philippines, Babuyan Islands, Calayan, Sitio Katanapan, Barangay Dibay. A Cuvier’s beaked whale (Ziphius cavirostris) was found stranded. The whale, a male measuring 5.18 meters, was already in a decomposed state when reported by local residents.

2025, April 2 (Date sometime in last week). Norway, Dverberg on the island of Andoya. Cachalot (sperm whale). The sperm whale washed ashore in the town in a moderate state of decomposition. It was a male animal about 15.7 meters long.
