Microearthquakes preceding a M4.2 Earthquake Offshore Istanbul

Izmit Earthquake on Seismic Hazards in Istanbul

We calculate the probability of strong shaking in Istanbul—an urban center of 10 million people—from the description of earthquakes on the North Anatolian fault system in the Marmara Sea during the past 500 years, and test the resulting catalog against the frequency of damage in Istanbul during the preceding millennium. Departing from current practice, we include the time-dependent effect of st...

A probable earthquake scenario near Istanbul determined from dynamic simulations

We perform numerical simulations of dynamic rupture processes along the North Anatolian fault in the Sea of Marmara, which poses a high risk to the nearby city of Istanbul. Several fault geometry models, nucleation points, and initial stress states are tested. The likelihood of each earthquake scenario is evaluated, and a probabilistic assessment of the ground-motion estimation is proposed. The...

Lifelines Performance of the Mw 8.8 Offshore BIOBÍO,Chile Earthquake

The paper will provide a summary of all lifelines performance in this strong earthquake. The paper will discuss the damage, emergency response, and recovery of electric power, telecommunication, transportation (roads and bridges), seaports, airports, water and wastewater, and their facilities. The impact as a result of the lifelines service interruption will be discussed; most important is the ...

Insights on earthquake triggering processes from early aftershocks of repeating microearthquakes

Characterizing the evolution of seismicity rate of early aftershocks can yield important information about earthquake nucleation and triggering. However, this task is challenging because early aftershock seismic signals are obscured by those of the mainshock. Previous studies of early aftershocks employed high-pass filtering and template matching but had limited performance and completeness at ...
