2000年、三宅島と神津島の間で約1 km³もの大規模なマグマ貫入が発生しました。その直後、約100 km離れた富士山では、それまでとは桁違いに多くの深部低周波地震が発生しました。さらにその後、箱根、伊豆半島東部、八丈島などでも通常とは異なる活動が相次ぎます。 これは、伊豆・小笠原の火山が地下でつながっていることを意味するのでしょうか。あるいは、三宅島から富士山までマグマそのものが移動したのでしょうか。 今回は、2000年前後の伊豆火山弧の活動、1986年伊豆大島噴火で観測された震源移動、そして伊豆大島周辺の海底火山の岩石学的研究をもとに、「火山同士は地下でどのようにつながっているのか」を解説します。 実際、伊豆大…

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.
