本州の真ん中に隠れた割れ目は、細い線か、大きな溝か。新潟県の糸魚川から静岡まで続く「溝の西の壁」に沿って3Dで飛び、産総研の地質図で地面を岩の年代で塗り、本州を東西に割って中身を抜くと、深さ6,000m以上の谷が現れます（深さ6,000mの穴を掘っても、底の古い岩に届かなかった溝です）。名前はフォッサマグナ、ラテン語で「大きな溝」。約2,000万?1,500万年前、日本海が観音開きに開いてできたこの溝が、なぜ今は見えないのか。長野で見つかった約1,300万年前のクジラの化石、溝の上に並ぶ火山、年3?4mmで高くなる南アルプスから3つの理由をたどります。最後は、電気の50Hz／60Hzの境（溝のせいではなく、偶然ほぼ重なる）や、大みそ…

How accurate are these YouTube video analytics?
View, like, and comment counts come from YouTube's public API and refresh regularly. Growth and revenue figures are estimates built from tracked historical data, so they can differ slightly from what the creator sees privately in YouTube Studio.
What is the outlier score?
How this video's views compare to the channel's usual Shorts or long-form video. A 2x score means double the usual views for that channel, 0.5x means half.
What is engagement rate and how is it calculated?
Likes and comments per view, compared to this channel's typical engagement rate — shown as above or below what's usual for the channel.
How is the revenue estimate calculated?
It's a rough public estimate based on a $0.7–$2.0 CPM (revenue per 1,000 views) applied to view count — not actual creator earnings, which depend on ad rates, audience geography, and monetization settings YouTube doesn't expose publicly.
Is this YouTube video analytics checker free?
Yes. You get 10 free channel and video analytics lookups per 24 hours without an account — logging in, which is also free, removes that limit entirely.
