Magellanic penguins, airbursts and the east coast of South America

2010, March 18. Airburst.

In 2010, 550 penguins were found on Brazil's coastline. They were believed to have starved to death. Before 2010, only roughly 10 dead penguins would be expected to be found ashore in a typical year.

2012, May 25. Airburst.

In June 2012, higher numbers were recorded, with 742 Magellanic penguins discovered in a decomposed state on the shores of Brazil. The causes of death were investigated. The birds were young and "natural causes" were assumed.

2023, February 14. Airburst.

In July 2023, more than 2000 dead penguins were washed up on the shores of Uruguay. According to Uruguayan authorities, 90% of these were juveniles without fat reserves and with empty stomachs. All carcasses tested negative for avian influenza. Other dead seabirds, sea turtles and sea lions were found on the coast of the Maldonado Department.

Sonic boom creates earthquake in Corsica

It will be interesting to see if anything results from these two meteors. Events like this were not unexpected this week.

2024, June 20. Italy/France, Tyrrhenian Sea - Mediterranean. Sonic Boom produced an earthquake in Corsica and also heard on the island of Elba. It happened at 4:30 in the afternoon. At Elba, the town of Campo nell’Elba, a nearby tracking station, “captured a seismic, acoustic event felt by everyone”. An earthquake has been ruled out. Similar events in 2012, 2016 and 2023 have yet to be explained. Six days before on June 14 a large fireball was observed travelling N.N.E across the Ligurin Sea north of Corsica. See map below.

Tribal hunts need to stop! The Gray whales are under threat

The Makah Tribe in Washington has won approval from the US to resume whale hunting for the first time in 25 years. The indigenous communities and the US government are ignorant of the environment. Apparently, both parties have been naive for thousands of years. Governments need more information to guide their decision-making. Selfishness and ignorance are not a good mix.

This does not make environmental sense when the Gray whale population is under threat.

Fireball off Rhode Island in North Atlantic

2024, June 8. USA, Rhode Island, Nantucket, North Atlantic. Fireball. Time: 07:17UT. I should have additional data on this event within a few days. It could lead to a marine animal disturbance in the following weeks.

List of recent stranding
