Iceland Volcano: Most Active Volcanoes In The World

A state of emergency has been declared in Iceland, with authorities urging residents to evacuate the coastal town of Grindavík due to a series of intense earthquakes in the southwest. The seismic activity, numbering nearly 800 quakes between midnight and 2 p.m. on Friday, is potentially linked to a volcanic eruption.

The Icelandic Meteorological Office reported that the earthquakes had varying depths, with the shallowest recorded at 3-3.5 kilometers (1.86-2.18 miles). The Civil Protection Agency of Iceland stated on Friday that a magma tunnel is forming, and there is a possibility it could extend to Grindavík. However, as of Friday evening, authorities have been unable to determine whether and where the magma might breach the surface.

Most active volcanoes

Creating a definitive ranking of the most active volcanoes can be subjective in certain instances. However, recent research has provided insights that firmly place the volcano claiming the top position as a deserving contender. Here are the world's most active volcanoes.


Mauna Loa
Mauna Loa, the largest volcano on Earth, reclaimed its title after a brief interruption in 2013. During that time, scientists had suggested that the Tamu Massif underwater feature might be the world's largest volcano, but subsequent information from National Geographic refuted that claim, casting doubt on its volcanic nature. Mauna Loa, with a history of erupting for approximately 700,000 years, poses a significant threat to nearby communities due to its regular lava flows.

Eyjafjallajokull
Eyjafjallajokull made headlines with its eruption in 2010. Although the eruption was relatively minor, the resulting ash plume triggered a worldwide air traffic crisis, leading to numerous flight diversions and cancellations. Its notable recent activity has elevated its status as one of the most famous volcanoes today.

Mount Vesuvius
Most active volcanoes worldwide pose a threat if you're in close proximity during an eruption. However, the attention often gravitates towards a specific volcano due to its geographical proximity to densely populated areas. A prime example is Mount Vesuvius, situated merely 5.5 miles (9 km) from the city of Naples, Italy, making it the most densely populated region with an active volcano globally.

The catastrophic eruption in 79 AD resulted in the burial of the cities of Pompeii and Herculaneum under layers of ash and lava. Notably, Vesuvius stands as the sole volcano on the European mainland to have erupted within the last century. Presently, it is acknowledged as one of the most perilous volcanoes globally, given its close proximity to Naples and its tendency to unleash violent, explosive eruptions.

Mount Merapi
Mount Merapi is believed to be the most prolific lava producer among all volcanoes globally. In October 2010, a heightened alert was issued for residents in the nearby areas, urging them to evacuate.

On October 25th, lava started spewing from the southern slopes, and the eruptions persisted throughout November. Tragically, the events led to the loss of approximately 350 lives and rendered many in the neighboring communities homeless. Mount Merapi is recognized as the most active volcano in Indonesia, with eruptions as recent as 2018, necessitating frequent evacuations in the region.

Sakurajima
Once an independent island volcano, Sakurajima fused with the Osumi Peninsula in Japan as its lava flows expanded. Since 1955, this volcano has been in a near-constant state of eruption, with numerous small explosions occurring annually, posing risks to the nearby city of Kagoshima.

A significant event took place on 18 August 2013 when the volcano erupted from the Showa crater, generating an ash plume soaring 3 miles (5,000 meters) high. This marked the 500th eruption of the year.
