Volcanodle
Puzzle #4 was Payun Matru.
The Payún Matrú volcanic field in Argentina includes a massive hawaiian-style shield volcano that lies 530 km from the oceanic trench. The 8 x 10 km alkaline caldera of Cerro Payún Matrú was formed after about 168,000 years ago. The high point of the massif, Cerro Payen stratovolcano, was constructed on the SW flank of the shield.

Volcanodle builds its record from Global Volcanism Program, Smithsonian Institution (Venzke, E. (ed.), Volcanoes of the World, volcano.si.edu). The description above comes from the same place the game credits on every reveal: A verbatim excerpt of the volcano's GVP Geological Summary. The puzzle itself is still playable in the archive, and every answer that has been and gone is listed on the past-answers page.
