Six Volcanoes Across the World Are Threatening Dangerous.

A total of 38 volcano eruptions where confirmed in the year 2014, as you can see on the wonderful graph below which falls into an average figure for the last 60 years or so. The largest eruption of the on the Volcanic Explosivity Index, ( VEI) in the last 14 years was a 5 on June the 4th 2011 at the Puyehue-Cordon Caulle in Chile and Argentina.

Periods of voluminous eruptions lasting 50 to 150 years (e.g., A.D. 300 450, 950 1060, 1607 1669) are followed by centuries of less productive activity, although at any time a violent outburst may occur. Such a revised history should be taken into account for eruptive models, magma output, internal plumbing of the volcano, petrological evolution, volcano mapping and civil protection. A careful.

Types of Volcanic Eruptions - Geology.

The most destructive volcano of known history is eruption of Tambora volcano in Indonesia in 1815. The death toll of 100,000 is the highest of all recorded volcano eruptions.The eruptive recurrence interval of Hualalai for all of Holocene time is on the order of 50 years (about 200 eruptions in 10,000 years). However, mapping and 14 C dating studies have indicated that eruptions have occurred in clusters (groups of several eruptions over a few hundred years), separated by several centuries of inactivity.This is a list of volcanic eruptions of the 20th century measuring a Volcanic Explosivity Index (VEI) of at least 4, as well as notable smaller eruptions. Note that there may be many other eruptions that have not been identified, and estimates for the size of eruptions can be subject to considerable uncertainties.


About 50 to 60 eruptions happen each month. Some volcanoes are in constant activity — Stromboli, Kilauea, or Sakurajima, for example. There are many examples of volcanoes which show some sign of renewed danger and then erupt within an hour, though more commonly, within one day. Most eruptions last hours but some continue for weeks and months.Some of the volcanic ash fell back down to the northwest of the volcano and buried crops and roofs under a layer up to 50 cm thick. In addition to eruption columns and ash fall, the eruption also caused hot mixtures of volcanic gases and rock debris (pyroclastic flows) to travel down the slopes of the volcano. Some of these pyroclastic flows turned into devastating mudflows (lahars) further.

This article and data visualizations explore the volcanic activity. A summary of some statistics about eruptions within the last 10,000 years and two new interactive visualizations that allow you to explore all recorded eruptions will be provided. Satellite image of Volcano Mount Tambora, Indonesia which in 1892 had the largest eruption with a volcanic explosivity index (VEI) of 7.

First, as populations increase, people end up living in many regions that were once considered remote, and if these happen to be volcanic regions then once unseen eruptions will now be reported. Plus the impact of volcanic events now ripples across the globe as seen in the 2010 eruption in Iceland. The same eruption, in 1500, would likely not have been as much trouble for the folks in England.

Cotopaxi erupted more than 50 times since 1738. The most violent historical eruptions of Cotopaxi volcano were in 1744, 1768, 1877, and 1904. its eruptions often produced pyroclastic flows and destructive mud flows (lahars). Some lahars have travelled more than 100 km and reached the Pacific to the west and the Amazon Basin to the east. At the moment, it has been dormant for over 70 years.

Ambae volcano is a very large volcano and is frequently active. In the recorded history, there have been many eruptions, every 10-50 years over the past 150 years. All have been from the summit craters, except one recorded in 1670’s when a lava flow occurred in the Ndui Ndui area. The current eruption is focused in the summit crater and there.

The last 600 years of apparent global volcanism can be displayed by plotting the number of volcanoes known to have been active each year (figure 2). At first glance the nearly exponential increase through recent centuries suggests that the planet may soon be overwhelmed by volcanic activity, but this increase tracks the striking growth of global population (dashed line on figure 1) that has.

People can get used to living near a volcano, but it is always a little dangerous. Scientists have estimated that at least 200,000 persons have lost their lives as a result of volcanic eruptions during the last 500 years. People set up homes on the slopes of volcanoes because of the rich, fertile soil produced. Parts of a volcano. Largest.
