1985 Puerto Rico floods landslide

The 1985 Puerto Rico floods produced the deadliest single landslide on record in North America, killing at least 130 people in the Mameyes neighborhood of barrio Portugués Urbano in Ponce. Saturated soils caused mudslides throughout Puerto Rico, although only one resulted in loss of life. In the hillside community of Mameyes, within Ponce, there was a block slide at around 3:00 am local time on October 7. A large slab of sandstone detached from a hill, moving about 250,000 cu yd (190,000 m3) of material down the hill. The intense rainfall triggered the landslide, although pre-existing conditions such as a leaking water main and poor sewage flow likely contributed to the event. The landslide destroyed about 90 houses, killing about 130 people; however, the death toll could have been as high as 300.

Ohio Stadium is an American football stadium in Columbus, Ohio, on the campus of Ohio State University. The stadium opened in 1922 as a replacement for Ohio Field and had a seating capacity of 66,210. In 1923, a cinder running track was added that was later upgraded to an all-weather track. Seating capacity gradually increased over the years and reached a total of 91,470 possible spectators in 1991. It is the largest stadium by capacity in the state of Ohio, and the third largest on-campus football stadium in the United States.

1826
Granite Railway opened

The Granite Railway was one of the first railroads in the United States, built to carry granite from Quincy, Massachusetts, to a dock on the Neponset River in Milton. The Granite Railway is popularly termed the first commercial railroad in the United States, as it was the first chartered railway to evolve into a common carrier without an intervening closure. The railroad was designed and built by railway pioneer Gridley Bryant and began operations on October 7, 1826.
