The January 15, 2022 eruption of Hunga Tonga-Hunga Ha'apai in the South Pacific produced an eruption plume that reached approximately 57 km in altitude — well into the mesosphere, and by a wide margin the tallest volcanic plume ever measured by satellite, surpassing the previous record (Pinatubo in 1991, which reached about 40 km). The same eruption also generated the most intense volcanic lightning storm ever recorded, with over 192,000 lightning events detected in a single six-hour window, and triggered a globally observed atmospheric pressure wave and tsunami.

The greatest altitude ever reached by a volcanic eruption plume, as directly measured by satellite observation.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
