The Doji bara famine (also Skull famine) of 1791–1792 in the Indian subcontinent was brought on by a major El Niño event lasting from 1789–1795 and producing prolonged droughts. Recorded by William Roxburgh, a surgeon with the British East India Company, in a series of pioneering meteorological observations, the El Niño event caused the failure of the South Asian monsoon for four consecutive years starting in 1789.The resulting famine, which was severe, caused widespread mortality in Hyderabad, Southern Maratha Kingdom, Deccan, Gujarat, and Marwar (then all ruled by Indian rulers). In regions like the Madras Presidency (governed by the East India Company), where the famine was less severe, and where records were kept, half the population perished in some districts, such as in the Northern Circars. In other areas, such as Bijapur, although no records were kept, both the famine and the year 1791 came to be known in folklore as the Doji bara (also Doĝi Bar) or the 'skull famine,' on account, it was said, of the 'bones of the victims which lay unburied whitening the roads and the fields.' As in the Chalisa famine of a decade earlier, many areas were depopulated from death or migration. According to one study, a total of 11 million people may have died during the years 1789–1792 as a result of starvation or accompanying epidemics of disease.

The 1991 eruption of Mount Pinatubo in the Philippines' Luzon Volcanic Arc was the second-largest volcanic eruption of the 20th century, behind only the 1912 eruption of Novarupta in Alaska. Eruptive activity began on April 2 as a series of phreatic explosions from a fissure that opened on the north side of Mount Pinatubo. Seismographs were set up and began monitoring the volcano for earthquakes. In late May, the number of seismic events under the volcano fluctuated from day-to-day. Beginning June 6, a swarm of progressively shallower earthquakes accompanied by inflationary tilt on the upper east flank of the mountain, culminated in the extrusion of a small lava dome.On June 12, the volcano’s first spectacular eruption sent an ash column 19 km (12 mi) into the atmosphere. Additional explosions occurred overnight and the morning of June 13. Seismic activity during this period became intense. When even more highly gas-charged magma reached Pinatubo's surface on June 15, the volcano exploded, sending an ash cloud 40 km (25 mi) into the atmosphere. Volcanic ash and pumice blanketed the countryside. Huge pyroclastic flows roared down the flanks of Pinatubo, filling once-deep valleys with fresh volcanic deposits as much as 200 m (660 ft) thick. The eruption removed so much magma and rock from beneath the volcano that the summit collapsed to form a small caldera 2.5 km (1.6 mi) across.Fine ash from the eruption fell as far away as the Indian Ocean and satellites tracked the ash cloud as it traveled several times around the globe. At least 16 commercial jets inadvertently flew through the drifting ash cloud, sustaining about $100 million in damage. With the ashfall came darkness and the sounds of lahars rumbling down the rivers. Several smaller lahars washed through the Clark Air Base, flowing across the base in enormously powerful sheets, slamming into buildings and scattering cars. Nearly every bridge within 30 km (19 mi) of Mount Pinatubo was destroyed. Several lowland towns were flooded or partially buried in mud. More than 840 people were killed from the collapse of roofs under wet heavy ash and several more were injured.Rain continued to create hazards over the next several years, as the volcanic deposits were remobilized into secondary mudflows. Damage to bridges, irrigation-canal systems, roads, cropland, and urban areas occurred in the wake of each significant rainfall. Many more people were affected for much longer by rain-induced lahars than by the eruption itself.
