***it sits on top of an extinct volcano in West Java, Indonesia,***
Reminds me of the old hard to find 1953 movie A FAIR WIND TO JAVA in which a temple with diamonds is sitting on the volcano Krakatoa when it explodes.
And then there is the old Mighty Mouse cartoon about Krakatoa Katie...doing her hochie coochie dance...first time this little kid got turned on by a mouse!
