About the Mechanism of Volcanic Eruptions

TL;DR

This paper introduces a new physical mechanism-based theory of volcanic eruptions, explaining various eruption types and formations through system imbalance criteria involving magma, crust, and fluid interactions.

Contribution

It proposes a unified physical model for volcanic eruptions, deriving an imbalance criterion and analyzing stratovolcano and caldera formation.

Findings

Derived a criterion for magma eruption based on system imbalance

Explained formation processes of stratovolcanoes and calderas

Discussed mechanisms behind high explosive silicic eruptions

Abstract

A new approach to the volcanic eruption theory is proposed. It is based on a simple physical mechanism of the imbalance in the system "magma-crust-fluid". This mechanism helps to explain from unified positions the different types of volcanic eruptions. A criterion of imbalance and magma eruption is derived. Stratovolcano and caldera formation is analyzed. High explosive eruptions of the silicic magma is discussed
