Questions
Question (1)
We collected gravity data on a slope in Avcılar where near the North Anatolian Fault Zone (NAFZ) . We think that, we can study or collected gravity data on any slope (there is a slope stability problem) and gravity value are affected by on that. However, we worry that why does the gravity change on the same measurement point in 7 days. The increasing value is approximately 38 mgal near to (NAFZ) in Turkey? The measurements were conducted with the CG-5 Scientrex device. The stress is increasing sharlpy or not? We asked it to you.? For the earhtquake prediction, Is these increasing is normal or not?
Sincerly.
