# List of volcanic eruptions in the 21st century

This is a list of volcanic eruptions in the 21st century with a volcanic explosivity index (VEI) of 4 or higher, and smaller eruptions that resulted in fatalities, significant damage or disruptions.
The largest volcanic eruption of the 21st century is the 2022 Hunga Tonga–Hunga Haʻapai eruption and tsunami, and the deadliest are the 2018 Volcán de Fuego eruption and the 2018 Sunda Strait tsunami.

## Large eruptions (VEI of 4 or higher, or plume height of at least 15 km)

| VEI | Volcano | Country | Year | Max plume height (km) | Material volume (km$^3$) | Fatalities | Notes |
| 4? | Mount Ruang | Indonesia | 2024 | 23 | | | Thousands of homes were destroyed. Volcanic ash was reported as far away as Manado and several areas in Gorontalo. Airlines from West Malaysia and Singapore cancelled flights to Sabah and Sarawak on 18 April due to reduced visibility. The eruption also prompted the shutdown of Sam Ratulangi International Airport in North Sulawesi. All 843 residents of Ruang island were evacuated to Manado, while 12,000 residents of Tagulandang were relocated to Siau Island by ship. On 17 and 30 April, authorities raised the volcano's alert level to four, the highest in Indonesia and issued a tsunami alert which led to orders for 11,000 residents and evacuees in Tagulandang to be moved to Manado in mainland Sulawesi, citing the risk of the volcano collapsing into the sea. |
| 4? | Sheveluch | Russia | 2023 | 20 | | | An eruption on April 11 ejected a cloud of volcanic gas and ash that reached a height of 20 km (12 mi) and spread over an area of 108,000 km$^2$ (42,000 sq mi). Pyroclastic flows from the eruption traveled up to 19 km (12 mi) away from the volcano. |
