Dear Imanuela Indah Pertiwi

Nobody likes to reveal such things. Especially when you see this being asked by a geophysicist. Good information is worth a lot and yet everyone wants to get it for free!

I have something about this in my notes, but since they don't pay for it, I haven't worked it out.

See what has been published as evidence:

Research Proposal 'The effect of lightning on the Earth's gravitational field'

Call me in Indonesia and I'll bring my notes. My salary is small, I'm not sure I'll be able to pay for the plane ticket!

Imanuela Indah Pertiwi ,

here are a few examples of active faults that have been identified using gravity data:

• San Andreas Fault, California: Gravity data has been used to map the San Andreas Fault, one of the most well-known and active fault lines in the world. The variations in gravity measurements help to identify the fault's structure and the density differences in the surrounding rocks.

• North Anatolian Fault, Turkey: This fault is another significant and active fault line. Gravity data, along with other geophysical methods, has been used to study its characteristics and to monitor its activity.

• Alpide Belt, Europe-Asia: The Alpide Belt, which includes several active faults across Europe and Asia, has been studied using gravity data to understand the tectonic processes and the distribution of stress along these faults.

Dear Andreas Schwarz, thank you very much. I think this is very useful.

Imanuela Indah Pertiwi ,

I found these articles with the help of MS-Copilot: I entered your problem, re-formulated a bit several times, and finally received this list... ;-)

I myself did not know the word "faults" in this context - to me, this word meant "error" so far... ;-)

Andreas Schwarz I never thought about using MS Copilot, but i will try to use it.
