火孔底、最深部の穴からは白い噴気が噴出していて、マグマの通り道である地下の火道につながっていると思う。過去に何回も噴火を繰り返し、今後もこの場所から噴火する可能性が高いと考えられている。

火孔底
火口南展望所の反対側から撮影した火孔底です。
最深部の白い噴気が噴出している穴は、マグマの通り道（火道）につながっているのではないかと思います。

火孔底の地表面温度は、1986年噴火後に低下してきていますが、近年は低下が止まりつつあるようにもみえます。
これが上昇に転じたり、噴気活動が活発になったり、火孔壁の崩落が頻繁になったるする火孔内の現象は、噴火の前兆として、とても重要です。

Thermal Emission Imaging System (THEMIS) image from the Mars Odyssey spacecraft reveals a unique Martian landscape. Light-colored, finger-like formations, initially thought to be salt deposits, are now identified as eroded volcanic ash, contrasting sharply with the dark surrounding sand within a 10km area of a larger crater. The image showcases the fascinating geological processes shaping the Martian surface.

What do you guys think of the smaller opening? Less moon jar, more bud vase. 🧐 I like both and may just keep doing both directions.
