Hi. I really like geology. What's Japan's geology like? Is it mostly sentimentary rocks? Is it volcanic rocks? It's a pretty long country so I'm guessing it varies a bit. Are there any karst regions? If so do those regions have any famious caves? All I am super aware of is it's near a fault line so earthquakes and tsunamis are common.
If anyone knows any cool facts please share I really like rocks.
From your questions, it may be not the kind of facts you wanted but a megathrust earthquake "may" happen in the future. The last one was the 1944 Tonankai earthquake followed by 1946 Nankaido earthquake (they often occur in pair). Those earthquakes have a return period of 90-200 years, so... (check the Nankai megathrust earthquakes wiki article if you want to know more)
Also because of that (and also the frequency of the earthquakes), they really share a special relation with sismology and geology in general. From the engineering of building that can resist earthquake to the detection of earthquakes with a system that can "almost" predict when earthquakes will happen and the awareness of the population, it's pretty crazy to see that kind of relation between a society and a scientific discipline.
As for the rock, I guess it should be volcanic rock since there is mount fuji (Japan is also a part of the ring of fire).
Edit: well, nevermind, the part facing the Pacific ocean is mainly volcanic rock while the part facing the sea of japan is mainly sedimentary rocks. That's interesting x) Also, I said Mt. Fuji but I just checked a list of volcanoes in Japan and yeah, pretty long list...
A few basic word also if you don't know them already 地震 (じしん) -> Earthquakes 津波 (つなみ) -> Tsunami 火山 (かざん) -> Volcano
地質学 (ちしつがく) -> Geology
Geology is like 地 (earth, soil) + 質 (quality, property) + 学 (study), so it's like "Study of the property/quality of the earth/soil) btw.
