The federal wildfire occurrence database lists 388 fires within 5 miles of Etna between 1992 and 2020, burning about 1,879 acres in total. None started naturally. 118 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Pedro
• Lisman
• Ellisonville
• Lawrence
• Lawrence Furnace
• Royersville

Every fire recorded in Lawrence County

Museums hold 375 specimens collected within 10 miles of Etna between 1890 and 1972: 299 Animalia, 45 Plantae, 30 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by Avery W. B., Bartley, F., Boepple and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

The federal mineral resources record lists 9 workings within 5 miles of Etna: 5 past producers, 3 producers, 1 plant. 4 still produce. What was taken out: Clay, Clay, Coal, Stone, Crushed/Broken. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Lawrence County

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1075815. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
