文摘

Parameter space study of prism size, prism compliance and sub-prism friction. Compliant prisms often cause greater slip and larger tsunamis. But some sets of parameters show decreased slip with greater compliance. Compliant prisms slow rupture speed, resembling “tsunami earthquakes”. Larger, more compliant prisms generate tsunamis more efficiently.
