The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The generation of the 2011 Tohoku-oki earthquake has been modeled by many authors by considering a dynamic weakening mechanism such as thermal pressurization (TP).
This first earthquake, which has been recorded as a 7.8Mw event, was followed at 15.24 local time (11.24 CET) by a second earthquake recorded as being a 7.5Mw event.Īn earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth’s lithosphere that creates seismic waves. Dimension reductionusing 1D or 2D models instead of 3D modelsis a commonly used simplification, but its consequences are not systematically studied. At 04.17 am local time (02.17 CET) on Monday 6 February 2023, the first of two extremely large earthquakes struck south eastern Turkey, near the Syrian border. Computer simulations are a powerful tool to understand earthquakes and they are often simplified to save time and energy.
