In 1257, a catastrophic eruption occurred at the Samalas volcano on the Indonesian island of Lombok. The event had a probable Volcanic Explosivity Index of 7, making it one of the largest volcanic eruptions during the current Holocene epoch. It created eruption columns reaching tens of kilometres into the atmosphere and pyroclastic flows that buried much of Lombok and crossed the sea to reach the neighbouring island of Sumbawa. The flows destroyed human habitations, including the city of Pamatan, which was the capital of a kingdom on Lombok. Ash from the eruption fell as far as 340 kilometres (210 mi) away in Java; the volcano deposited more than 10 cubic kilometres (2.4 cu mi) of rocks and ash. The eruption was witnessed by people who recorded it on the Babad Lombok, a document written on palm leaves. It left behind a large caldera that contains Lake Segara Anak. Later volcanic activity created more volcanic centres in the caldera, including the Barujari cone, which remains active. The aerosols injected into the atmosphere reduced the solar radiation reaching the Earth's surface, causing a volcanic winter and cooling the atmosphere for several years. This led to famines and crop failures in Europe and elsewhere, although the exact scale of the temperature anomalies and their consequences is still debated. The eruption may have helped trigger the Little Ice Age, a centuries-long cold period during the last thousand years. Before the site of the eruption was known, an examination of ice cores around the world had found a large spike in sulfate deposition around 1257, providing strong evidence of a large volcanic eruption having occurred somewhere in the world. In 2013, scientists linked the historical records about Mount Samalas to these spikes.

The 1970 Bhola cyclone was a devastating tropical cyclone that struck East Pakistan (present-day Bangladesh) and India's West Bengal on November 11, 1970. It remains the deadliest tropical cyclone ever recorded and one of the world's deadliest natural disasters. At least 500,000 people lost their lives in the storm, primarily as a result of the storm surge that flooded much of the low-lying islands of the Ganges Delta. Bhola was the sixth and strongest cyclonic storm of the 1970 North Indian Ocean cyclone season.The cyclone formed over the central Bay of Bengal on November 8 and traveled northward, intensifying as it did so. It reached its peak with winds of 185 km/h (115 mph) on November 10, and made landfall on the coast of East Pakistan on the following afternoon. The storm surge devastated many of the offshore islands, wiping out villages and destroying crops throughout the region. In the most severely affected Upazila, Tazumuddin, over 45% of the population of 167,000 was killed by the storm. The Pakistani government, led by junta leader General Yahya Khan, was criticized for its delayed handling of relief operations following the storm, both by local political leaders in East Pakistan and by the international media. During the election that took place a month later, the opposition Awami League gained a landslide victory in the province, and continuing unrest between East Pakistan and the central government triggered the Bangladesh Liberation War, which led to a genocide and eventually concluded with the creation of the independent country of Bangladesh.
