Greece Turkey Dispute Island Earthquake Magnitude Vs Peak Ground Acceleration

Earthquake damage data is of vital importance both as an indicator of the likely performance of buildings in future earthquakes as well as for the calibration of existing theoretical analytical models regarding building vulnerability.

Turkey chili with beans and corn. Pga min pgauh max pgad84th 05 where pgauh uniform hazard peak. Many factors influence the strength of earthquake shaking at a site including the earthquakes magnitude the sites proximity to the fault the local geology and the soil type. Greece is one of the most seismically active territories in europe and worldwide.

Dependence of strong ground motion on magnitude distance site geology and macroseismic intensity for shallow earthquakes in greece. It was demonstrated by ansal and tonuk 2007 that if limited number of input acceleration time histories eg. More than 250 structures throughout the united states have been outfitted with seismic.

We wont go too deep into the science but peak ground acceleration is essentially the measurement of how hard the earth shakes in a given area. All we need to say is that the really dark red bits are turkey. The magnitude of earthquake is determined from measurements on seismographs whereas the intensity is determined from effects on people human.

Magnitude and intensity measure various characteristics of earthquake. Ground shaking is the primary cause of earthquake damage to man made structures. The maximum considered earthquake geometric mean mceg peak ground acceleration pga values of the 2015 nehrp recommended seismic provisions the 2016 ascesei 7 standard and the 2018 international building code can be calculated from the downloadable data via the following equations.

Therefore real time peak ground acceleration pga distribution directly related to seismic damage is of. Three records as specified in some earthquake codes are used even with scaling to the same peak ground acceleration pga amplitudes for site response analysis the results in terms of pga peak ground velocity pgv and elastic. And we all know that on any map red usually does not equal anything good.

It was demonstrated by ansal and tonuk 2007 that if limited number of input acceleration time histories eg. How often do earthquakes hit in turkey and how hard. The analysis of damage data collected shortly after the august 14 2003 lefkada island greece earthquake revealed the higher vulnerability of masonry buildings.

I peak horizontal acceleration velocity and displacement. The friday afternoon quake that struck turkeys aegean coast and north of the greek island of samos registered a magnitude that turkish authorities put at 66 while other seismology institutes.
