Powerful volcanic eruptions are a … Significant volcanic eruptions in the Philippines over the past 2000 years The following list shows all volcanoes of the last 2000 years with significant damage. In a volcanic eruption, lava, volcanic bombs and ash, and various gases are expelled from a volcanic vent and fissure.While many eruptions only pose dangers to the immediately surrounding area, Earth's largest eruptions can have a major regional or even global impact, with some affecting the climate and contributing to mass extinctions. Satellite image of Volcano Mount Tambora, Indonesia which in 1892 had the largest eruption with a volcanic explosivity index (VEI) of 7. Data is reported through the last data update (10 December 2020). By some estimates, it was the largest volcanic eruption in recorded history. This article and data visualizations explore the volcanic activity. ... Today global temperatures are rising at unprecedented rates and most of the warming occurred in the past 35 years… Largest volcanic eruptions (2000-2010) #1 Post by HurricaneBill » Thu May 13, 2010 11:50 pm During the past decade, there were several volcanoes that had eruptions measuring VEI-4 on the Volcanic Explosivity Index.

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. Over the past 2,000 years, volcanoes have played a larger role in natural temperature variability than previously thought, and their climatic effects may have contributed to past societal and economic change, an international team of researchers found. Human death toll Volcano Location Year Source(s) 71,000 to 250,100+ (regarded as having caused the Year Without a Summer, creating famines and epidemics across the Northern Hemisphere) : Mount Tambora: Indonesia: 1815: 36,000+ Most of these deaths were not attributed to the eruption itself, but to the tsunami generated by it.
