Fagradalsfjall mountain erupted in March which was the first ever for the area following a strong seismic crisis. Erta Ale Danakil depression, Ethiopia. Erta Ale is famous for its continous lava lake which has been active during most of the past decades since it was first discovered in the s.
Nyiragongo Congo. With more than 13, islands, Indonesia leads the world with the largest number of active volcanoes. The areas volcanoes have also produced the most fatalities.
Sinabung Sumatra, Indonesia. Dukono Halmahera, Indonesia. Ibu Halmahera, Indonesia. Merapi Central Java, Indonesia. Semeru East Java, Indonesia. Lewotolo Lesser Sunda Islands. One of Mexico's most active volcanoes. In the past large eruptions have produced giant mud flows that have buried Atzteque settlements, even entire pyramids according to historians. Santiaguito Guatemala. The most prominent of a chain of large volcanoes that rises dramatically above the Pacific coastal plain of Guatemala.
An eruption in devastated much of SW Guatemala. Fuego Guatemala. One of Central America's most active volcanoes. It often features spectacular intense lava fountains, while producing tall ash plumes. Continued outpouring of gases has killed people since then and a rise in the lava lake in has led researchers to suggest that the volcano may erupt again by Located 30 miles 48 km south of the capital city of Manila, Taal volcano is the second most active in the Philippines. However, this volcano is notable due to its fatality rate over the years, with around people having been killed.
Due to it's proximity to dense population centers, the volcano remains a risk. Now, the volcano was been fairly quiet since , but erupted again in January of this , spewed ashes to as far as Metro Manila, and parts of Central Luzon. Ashfalls and volcanic thunderstorms forced evacuations and these were followed by magma eruptions with a lava fountain accompanied by thunder and lightning. A total of 39 people died in the eruption, from either refusing to evacuate or from health-related problems during the evacuation.
Mount Merapi is thought to have produced more lava flow than any other volcano anywhere in the world. In October of , a high-alert was raised for people living in the surrounding areas, who were warned to evacuate.
On the 25th of October lava began erupted from its southern slopes. The eruptions continued throughout November, eventually causing the deaths of around people and left many in the surrounding population homeless. It's known as the most active volcano in all of Indonesia, erupting as recently as , and causing frequent evacuations in the region.
Galeras's summit rises an impressive 2,65 miles 4, meters above sea level and has been quite active for millions of years. It is thought that Galeras has been an active volcano for around a million years, but the first recorded eruption was in An eruption over , years ago actually expelled 15 cubic kilometers of material into the surrounding landscape and formed a caldera.
The volcano lies near the city of Pasto and poses a threat. Notably, in , scientists thought this volcano had gone dormant, but just 10 years later it erupted. After that, in , it erupted during a Decade Volcano conference in Pasto, killing 6 scientists who had mounted an impromptu expedition to the crater, along with three tourists. Activity in recent times continues at a low level, dusting local areas in ash and presenting a risk to the nearby residents.
An eruption marked as "continuing" does not always mean persistent daily activity, but indicates at least intermittent eruptive events without a break of 3 months or more. Detailed statistics are not kept on daily activity, but generally there are around 20 volcanoes actively erupting on any particular day ; this is a subset of the normal with continuing eruptions. Additional eruption data is available for recent years. The most recently started eruption is at the top, continuing as of the Stop Date given.
An eruption listed here might have ended since the last data update, or at the update time a firm end date had not yet been determined due to potential renewed activity. Complete updates are done about every weeks, but information about newer eruptions can be found in the Weekly Report. Current Eruptions. Gas measurements showed that sulfur dioxide emissions had increased from tons per day recorded on 14 October to tonnes per day.
Additionally, carbon dioxide increased from to tonnes per day and hydrogen sulfide increased from 10 to 38 tonnes per day. The gas data suggested that a pulse of gas was rising from molten material at depth. Temperatures in the main vent area were as high as degrees Celsius, similar to temperatures first measured in September and onward. Very minor ash emissions were visible and deposits only extended around the active vents.
The lake had slightly deepened from recent rainfall. Report for Krakatau PVMBG reported that during periods of clear weather during November white plumes from Anak Krakatau were visible rising as high as m above the summit. White-to-gray plumes were seen in webcam images during November rising m and crater incandescence was visible three times. The Alert Level remained at 2 on a scale of , and the public was warned to remain outside of the 2-km-radius hazard zone from the crater.
As many as lava avalanches traveled a maximum of 2 km SW. One pyroclastic flow traveled 2 km SW. The Alert Level remained at 3 on a scale of , and the public was warned to stay km away from the summit based on location. The events were accompanied by a series of four short-lived plumes that rose less than 1 km above the lake. Text on this page is printable and can be used according to our Terms of Service.

Most are located around the Pacific Ocean in what is commonly called the Ring of Fire. A volcano is defined as an opening in the Earth's crust through which lava, ash, and gases erupt.
The term also includes the cone-shaped landform built by repeated eruptions over time. Teach your students about volcanoes with this collection of engaging material. A volcano is a feature in Earth's crust where molten rock is squeezed out onto the Earth's surface. Along with molten rock, volcanoes also release gases, ash, and solid rock.
