Cause and mechanism of great earthquakes due to highly compressed methane gas mass trapped in subduction faults

Abstract

This paper uses the highly compressed methane gas mass model to interpret and explain the occurrence of great earthquakes at subduction fault with long recurrence intervals[1]. The gas model can be described as follows with the reference to Figure below. The subduction faults are weak zones and can become gas reservoirs generated in deeper rocks. With time t, the mass M(t), volume V(t), pressure P(t) and temperature T(t) of the reservoir gas can change and increase. At the fault rupturing of great earthquakes (t = 0), a huge amount of highly compressed gas mass ...
