RIEDEL MEGASHEARS R' AND THE TREND TO GRAVITATIONAL EQUILIBRIUM AS MAIN FACTORS OF TSUNAMIGENIC EARTHQUAKES
Published 2015-09-01“…Such style of shear formation has been explained in various waysare proposed (Fig. 15–16), and the main point of the explanations is joining of small tensile fractures by means of larger shear fractures. However, our experiments with wet clay (Fig. 31–35) show that even artificially created ’Riedel shears’ show nearly a zero extension under loading followed by shearing, which casts doubt on possibile occurence ofshear fractures as such without involvement of smaller tenson joints.While being not satisfied with the results of our experiments, we carried out numerical simulations of the evolution of Riedel shears, R and R' for different values of lithostatic pressure (which is actually impossible in experiments with equivalent materials) and angles of shearing. …”
