Solving volcanic eruptions triggers

Large numbers of people continue to be exposed to volcanic eruptions because of their proximity. Therefore, understanding the volcanic activity of drivers is important to better predict future eruptions and develop mitigation strategies. To this end, the latest article in Natural Assessments – Earth and Environment It explores a variety of factors that contribute to a magical explosion.

Satellite-based remote navigation or ground-based methods may only show limited data. Volcanologists often have to turn to the chemistry and texture of volcanoes to understand their magical development.

Much depends not only on the speed at which magma accumulates in a volcano but also on its operation. The authors note that although the risk of volcanic eruption increases with the exploding magma, the volatile elements are removed from the magma, allowing it to be further compressed, which can be reduced over time. The continual construction of the immutable rich magma pushes the system to critical conditions and ultimately leads to an explosion.

The tower is important

A large internal explosion triggers a magma “injection” from deep reservoirs to deep, this phenomenon is also known as magma reservoir collapse. An earlier study in 2012 suggested that the Bronze Age (00 1600 BC) in Santorini, Greece, had a similar effect.

Another potential trigger is rapid cooling and crystallization of magma. This leads to low levels of fluctuations from low density. This increases the pressure in the magma compartment and is a real stimulus. Explosions in Calcutta, Chile (2015) and Kellogg, Indonesia (2014) are a case in point.

The role of climate change

There are equally important external factors that can trigger an explosion. Climate change is a striking example. During the Middle Ages, when ice melts, rocks move with the melting of ice. This can cause short-term depression, which in turn can lead to magical and volcanic activity. Similarly, rising sea levels can also affect magical activity.

The authors note the strong link between volcanic eruptions, although not immediately after the quake. He argued that earthquakes could quickly lead to the destruction of iron-rich magnets. Of course, volcanic eruptions can also cause earthquakes.

Rainfall problem

In addition, since no magma rock is in nature, and gas / magma transport depends heavily on the host rock, precipitation is a major influence on volcanic activity by changing peripheral pressure. Historical observations have shown that there is a strong link between volcanic eruptions and increased rainfall. A significant example is The 2018 record-breaking volcanic eruption paved the way for volcanic eruptions in the United States, Hawaii, and Kilauea.

Rain also affects the hydrothermal pressure of the knees, leading to mineral collapse and eventually dome collapse. Rain helps to reduce the pressure in the lava, which causes it to explode. The Soufrière Hills, Montserrat, is believed to have been the cause of the explosion. Unzen, Japan; Morapi Volcano, Indonesia and Mount Helen, USA.

Finally, for all of the above reasons, a high-pressure magnet must go into the mouth of a volcano.

In addition to the magma characteristics we discussed above, the study examines a few key mechanisms by which this occurs.

  • * The magma fluid can be broken down by the surrounding shell, allowing it to be transported upward. Beyond certain stress points, magma transport can further widen the fractures around the walls of the magma room.
  • * Volcanic Structure – A large volcano tries to hold magnificent reservoirs to further erode the rock and prevent further demolition.
  • * Contrary to popular belief, the magnet has a cylindrical discharge from the top. Depending on the pressure, the distribution of the magnetic field may change frequently, even after a few months.

The authors point out that geophysical observations often cover the evolution of the volcanic system, and there is a poor understanding of magical behavior. It is often impossible to study magma reservoirs. In the long run, he hopes the study will lead to the development of better, more proxy, magma construction and transportation solutions that will lead to more accurate and well-compacted volcanic models.

“It is important to know whether to leave the population or not, and we hope that our study will help reduce the impact of volcanic activity on our society,” said Luca Carichi in the magazine.
