Hurricane Maria

Hurricane Maria was a deadly Category 5 hurricane that devastated the northeastern Caribbean in September 2017, particularly Dominica, Saint Croix, and Puerto Rico. It is regarded as the worst natural disaster in recorded history to affect those islands. Total monetary losses are estimated at upwards of $91.61 billion (2017 USD), mostly in Puerto Rico, ranking it as the fourth-costliest tropical cyclone on record. The total death toll is 3,059: an estimated 2,975 in Puerto Rico, 65 in Dominica, 5 in the Dominican Republic, 4 in Guadeloupe, 4 in the contiguous United States, 3 in the United States Virgin Islands, and 3 in Haiti. On September 20, an eyewall replacement cycle weakened Maria to a high-end Category 4 hurricane by the time it struck Puerto Rico.

1971
Hurricane Irene-Olivia

Hurricane Irene-Olivia was the first actively tracked tropical cyclone to move into the eastern Pacific Ocean from the Atlantic basin. It originated as a tropical depression on September 11, 1971, in the tropical Atlantic. In the Atlantic, Irene produced moderate rainfall and winds along its path, although impact was greatest in Nicaragua where it moved ashore as a hurricane. A total of 96 homes were destroyed, and 1,200 people were left homeless. After reaching the Pacific Ocean on September 20, the depression restrengthened to attain tropical storm status; upon doing so, it was re-designated by a new name, Olivia.

Johannes Rudolph Hint was an Estonian scientist and the only person to create and successfully run a limited company under the communist planned economy of the Soviet Union. With his company, Dessim Ltd, he earned millions for the Soviet Union. His most important scientific invention was the building material silikaltsiit (Laprex), which was developed through the execution of the disintegrator system. His inventions are still widely used in Germany, Austria, the United States, Japan and Russia.

1498 Meio earthquake

The 1498 Meio earthquake occurred off the coast of Nankaido, Japan. It had a magnitude estimated at 8.6 Ms and triggered a large tsunami. The death toll associated with this event is uncertain, but between 5,000 and 41,000 casualties were reported. The tsunami caused by the Mei? Nankaid? earthquake washed away the building housing the statue of the Great Buddha at K?toku-in in Kamakura, although the statue itself remained intact.
