On the evening of October 30, 2022, a pedestrian suspension bridge over the Machchhu River in Morbi, Gujarat, partly failed while crowded with visitors. The sudden collapse killed at least 135 people and injured many more.

2020 Aegean Sea earthquake
On October 30, 2020, a shallow Mw 7.0 earthquake struck the Aegean Sea near the Greek island of Samos, producing strong shaking felt across the eastern Aegean and western Turkey, a locally significant tsunami that flooded harbors, and deadly building collapses in İzmir.

1983 Erzurum earthquake
On October 30, 1983, a shallow, mid‑6 magnitude earthquake struck eastern Turkey with an epicenter near Horasan in Erzurum Province, leveling stone houses across remote villages and small towns in Erzurum and neighboring Kars. The quake exposed the vulnerability of unreinforced masonry in mountainous rural settings, sent rescue teams down narrow mountain roads, and left hundreds to a few thousand dead and many more injured as communities rebuilt under winter's approach.

Tsar Bomba (RDS‑220)
On October 30, 1961, the Soviet Union detonated RDS‑220—commonly called Tsar Bomba—over the Sukhoy Nos test site on Severny Island, Novaya Zemlya. Engineered to be the largest thermonuclear device ever built, the bomb’s tested configuration produced about a 50‑megaton yield, creating a mushroom cloud and shock waves recorded around the world and reshaping how governments and scientists thought about atmospheric testing.

Hungarian Revolution of 1956
In Budapest on October 23, 1956, a student demonstration that began with a 16‑point program of demands exploded into a nationwide uprising against Soviet‑backed Stalinist rule. For weeks Hungarians fought in the streets, briefly installed a reform government under Imre Nagy and declared neutrality; on November 4 the Soviet Union sent overwhelming force to crush the revolt. Thousands were killed or wounded, hundreds executed or imprisoned, and nearly 200,000 fled the country — yet the memory of October lived on and helped shape Hungary's eventual break from Communist rule.

Sinking of the SS Principessa Mafalda
On October 25, 1927, the Italian passenger liner SS Principessa Mafalda foundered off the coast of Brazil, in the approaches to Santos and São Vicente, after progressive flooding and an uncontrollable list. Carrying hundreds of emigrants, passengers and crew on the Italy–South America run, the ship’s chaotic evacuation and the imperfect rescue that followed left several hundred dead and reshaped public scrutiny of emigrant shipping practices.
