The pin covers August, the month the source's own statistics section is built around.

  Starts 06/30/2020ESTIMATED65% CONFIDENCE6.2 years agoEstimated: Wikipedia's^[2] infobox gives the topping out as June 2020 (its source, urban.com.au, reported it on 10 June 2020) without settling a day in the infobox, so the month's last day stands in. Completion followed in September 2020.

  Australia 108 topped out at level 100 in Melbourne's Southbank, becoming the tallest building in Australia by roof height and the tallest residential tower in the Southern Hemisphere; construction was completed three months later, in September 2020.

  Mount Tambora Erupts and Steals the Following Summer

  Mount Tambora, Sumbawa, Indonesia

  

  Starts 04/10/1815CONFIRMED90% CONFIDENCE211.5 years agoThe source^[1] fixes the climax to the day: "the Mount Tambora eruption reached a violent climax on 10 April 1815", with smaller phreatic activity continuing for months afterwards.

  The most powerful volcanic eruption in recorded history threw 37-45 cubic kilometres of rock into the atmosphere from Sumbawa. Its veil of ash cooled the planet enough to give 1816 the name the Year Without a Summer.

  Total Solar Eclipse Crosses Australia

  Point of greatest eclipse at sea, off Australia

  

  Starts 12/26/2038 12:58AMSCHEDULED82% CONFIDENCEin 12.3 yearsNASA's^[1][2][3] eclipse catalogue gives the instant of greatest eclipse as 00:58:46 UT on 2038-12-26 (01:00:10 TD, the two separated by delta-T), from Saros series 142. Eclipse circumstances are computed from orbital mechanics, so the date and time are exact centuries ahead.

  The Moon's shadow touches down at 00:58:46 UT on 2038-12-26, and the total phase lasts up to 2 minutes 18 seconds along a path 95.3 km wide crossing Australia, New Zealand and the South Pacific. A partial eclipse is visible from southeastern Asia, the East Indies, Australia, New Zealand, the South Pacific and Antarctica.

  The Bhola Cyclone Kills at Least 300,000 in the Ganges Delta

  Bhola Island, Ganges Delta, Bangladesh

  

  Starts 11/12/1970CONFIRMED90% CONFIDENCE55.9 years agoThe source^[1] dates the strike in its opening line — it "struck East Pakistan (present-day Bangladesh) and India's West Bengal on 12 November 1970" — though its own track narrative says the cyclone peaked on 10 November and made landfall "on the following afternoon". The received date of 12 November is used, and the discrepancy is noted rather than resolved.

  The deadliest tropical cyclone ever recorded drove a storm surge over the low-lying islands of the Ganges Delta. At least 300,000 died, and the Pakistani government's response helped set off the Bangladesh Liberation War.
