One volcano going off 15 miles away, and another one going off 30 miles away
Is that because of climate change? Asking for a friend.
No , the whole Hawaiian chain of Islands ... is volcanic .
there is a "hot spot" in the Earth's mantle
that is stationary , for the last 40 million years anyway
and as the ocean floor drifts over ... islands pop up through the hotspot . ( still drifting northwest at about 3 and 1/2" per year )
The process has been happening for millions of years .
( there is a similar hotspot underneath what is now the Yellowstone area )
The big island of "Hawaii" is the newest and most active in the Hawaiian chain , at about half a million years old
While Kauai is older , at just over 5 million years old
But speaking of climate change , The National Observatory atop Hawaii's tallest volcano
is where evidence for climate change was first gathered .
