Tephra Toil

As a vulcanologist of the future you have an advanced system for scanning tephra as it is thrown from the volcano.

In order to complete your research you must scan all the types of tephra and escape the volcano with your precious research.


  • Movement — ⬅️ ➡️
  • Dive —  ⬇️ (for fun!)
  • Start / restart at game over — ❎ / X

Get close to the rising tephra in order to scan it, the more you scan the closer you get to completing your research and furthering humanity's understanding of hot flying rock.

The word "tephra" refers to the fragmented material thrown from volcanic eruptions.

Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism.
