The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
A volcanic eruption is one of the most powerful forces in nature, a seemingly unstoppable phenomenon that can have far-reaching impacts far beyond the area surrounding the volcano itself. When a ...
Volcanic ash deposits on a parked McDonnell-Douglas DC-10-30 during the 1991 eruption of Mount Pinatubo, causing the aircraft to rest on its tail.While falling ash behaves in a similar manner to snow, the sheer weight of deposits can cause serious damage to buildings and vehicles, as seen here, where the deposits were able to cause the 120 ton airliner's centre of gravity to shift.
Tephrochronology is a geochronological technique that uses discrete layers of tephra—volcanic ash from a single eruption—to create a chronological framework in which paleoenvironmental or archaeological records can be placed. Often, when a volcano explodes, biological organisms are killed and their remains are buried within the tephra layer.
Two people wear hoodies and masks to shield themselves from the ash emitted by the Popocatépetl volcano in Atlixco, Mexico, on May 22, 2023. The volcano's activity has increased over the last ...
Mexico’s most dangerous active volcano spewed ash and smoke on Tuesday, with photos showing massive columns of gray emissions – large enough to ground nearby flights.
The International Volcanic Health Hazard Network (IVHHN) is an organization that provides research and information on the health hazards and impacts of volcanic eruptions. . IVHHN work covers a range of research areas including volcanology, toxicology, public health and exposure science, with the goal of determining the health impacts of volcanic emissions and how to protect exposed communit
A volcanic eruption could destroy the Icelandic town of Grindavik or lead to extensive ash clouds, experts have warned.. The country has been shaken by more than 800 small earthquakes today alone ...
