## Where it stands

**Disputed** None pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- Lights correlate with local seismic activity.

## What would rule it out

- No seismicity strong enough in the valley.

## Evidence none for · 1 against

[The 2024 survey judged seismicity in the valley too weak to sustain such a source.](https://mysteriesdept.com/mysteries/hessdalen-lights/evidence/EVD0D0NDX861A2D/the-2024-survey-judged-seismicity-in-the-valley-too-weak-to)
