1930 natural disasters

The 1930 Atlantic hurricane season was a very inactive Atlantic hurricane season. It was the second least active on record in terms of tropical storms forming, only behind 1914, with only three systems reaching tropical storm intensity. Of those three, two reached hurricane status, both of which also became major hurricanes, Category 3 or higher storms on the Saffir–Simpson hurricane wind scale. The first system developed in the central Atlantic Ocean on August 21. Later that month, a second storm, the Dominican Republic hurricane, formed on August 29. It peaked as a Category 4 hurricane with winds of 155 mph (250 km/h). The third and final storm dissipated on October 21.

The 1930 Meuse Valley fog between 1 December and 5 December, killed 63 people in Belgium owing to a combination of industrial air pollution and a localized weather inversion.

The 1930 Curuçá River event refers to the possible fall of objects on 13 August 1930 over the area of Curuçá River in Brazil. It is based on the account of a single investigator who interviewed witnesses to the purported event and then wrote a letter to the Vatican Observatory.
