In the interim, Greece had become a republic again, making it a better prospect for fieldwork. “The thing about Iran is that it’s being shortened but Greece and Western Turkey are being stretched,” says McKenzie. “When things are being shortened it’s extremely hard to see where the faults are but when they’re in extension it’s really easy.” McKenzie and JacksonJames Jackson (1954-present) of the University of Cambridge works on active deformation of the continents, focusing on earthquake source seismology alongside geomorphology, space geodesy and remote sensing. He is interested in quantifying not only the deformation from individual fault ruptures but also in how individual earthquakes combine to produce the landscape of active tectonic regions. toured Greece and Western Turkey, driving about 10,000 miles in six weeks, and were surprised by the clear visibility of faulting in the landscape. “We knew that it was normal faulting from the fault plane solutions but we had no idea how obvious it was in the field.”
How did the ideas on the relationship between earthquakes and continental deformation develop?
