THE VAULT DOCUMENT
Environmental Evidence
Environmental evidence refers to measurable conditions, observations or physical characteristics of an environment that are presented as documentation of an event, phenomenon, location or claim.
Within The Vault, environmental evidence is used when investigating:
- Reported hauntings.
- UFO and UAP cases.
- Cryptid encounters.
- Unexplained events.
- Historical locations.
- Scientific anomalies.
Environmental evidence differs from direct witness testimony because it focuses on measurable or observable conditions within a location rather than personal experiences.
Environmental evidence can provide important information about a case, but measurements or observations must be correctly collected, interpreted and compared against possible conventional explanations.
Role of environmental evidence
Environmental evidence may include:
- Temperature measurements.
- Electromagnetic field readings.
- Weather conditions.
- Geological features.
- Atmospheric conditions.
- Lighting conditions.
- Sound levels.
- Air quality.
- Radiation measurements.
- Physical changes within a location.
Examples include:
- A sudden temperature change recorded during a paranormal investigation.
- Unusual electromagnetic readings near a reported sighting location.
- Environmental conditions affecting a UFO observation.
- Geological features associated with local legends.
Evaluating environmental evidence
Environmental evidence should be assessed using several factors.
Measurement accuracy
The reliability of environmental evidence depends on:
- Quality of equipment.
- Calibration.
- Recording methods.
- Measurement location.
- Operator experience.
- Environmental conditions.
A reading is only meaningful if the method used to obtain it is understood.
Baseline measurements
Environmental evidence should ideally be compared against normal conditions.
Consider:
- What are typical readings for the location?
- Were measurements taken before and after the reported event?
- Are there natural variations?
- Were control measurements collected?
A measurement is more useful when there is a comparison point.
Equipment limitations
All equipment has limitations.
Factors include:
- Accuracy range.
- Sensitivity.
- Calibration.
- Interference.
- User error.
- Environmental effects.
A device recording an unusual reading does not automatically indicate an unusual cause.
Documentation
Environmental evidence should include:
- Date and time.
- Location.
- Equipment used.
- Conditions during measurement.
- Methodology.
- Raw data where available.
Poor documentation reduces the ability to independently assess findings.
Types of environmental evidence
Temperature changes
Temperature measurements are commonly collected during paranormal investigations.
Reports may include:
- Sudden cold spots.
- Localised temperature changes.
- Unusual fluctuations.
Possible explanations include:
- Air movement.
- Building design.
- Heating systems.
- Ventilation.
- Human presence.
- Equipment limitations.
A temperature change alone does not establish a paranormal cause.
Electromagnetic measurements
Electromagnetic field (EMF) readings are frequently used in paranormal investigations.
Reports may involve:
- Unusual readings.
- Sudden fluctuations.
- Localised electromagnetic changes.
Possible sources include:
- Electrical wiring.
- Mobile devices.
- Appliances.
- Radio signals.
- Environmental interference.
The relationship between electromagnetic fields and paranormal claims remains debated.
Weather and atmospheric conditions
Environmental conditions can affect observations.
Factors may include:
- Fog.
- Clouds.
- Wind.
- Temperature inversions.
- Atmospheric phenomena.
- Visibility.
Weather information is particularly relevant in:
- UFO reports.
- Apparition sightings.
- Outdoor encounters.
Geological evidence
Geological features may contribute to reports or legends.
Examples include:
- Caves.
- Rock formations.
- Fault lines.
- Unusual landscapes.
Geology may explain environmental conditions that influence perception or local folklore.
Acoustic environment
Sound conditions can affect reports of unusual events.
Consider:
- Background noise.
- Building acoustics.
- Echoes.
- Natural sounds.
- Human activity.
Environmental acoustics are especially relevant when investigating alleged footsteps, voices or unexplained sounds.
Environmental evidence in paranormal investigations
Paranormal investigators often collect environmental data using:
- Thermometers.
- EMF meters.
- Audio recorders.
- Cameras.
- Data loggers.
- Environmental sensors.
The Vault distinguishes between:
Measurement
A recorded environmental condition.
Example:
"An EMF meter recorded a change from 1 milligauss to 4 milligauss."
Interpretation
The explanation proposed.
Example:
"Investigators suggested the change may have been associated with paranormal activity."
The second statement requires additional evidence.
Common explanations for environmental anomalies
Many environmental observations may have conventional explanations.
These include:
- Electrical systems.
- Building materials.
- Weather.
- Natural geological activity.
- Equipment error.
- Human activity.
- Animals.
- Environmental fluctuations.
Investigations should consider ordinary explanations before unusual ones.
Environmental evidence and scientific investigation
Scientific investigation requires:
- Controlled conditions.
- Repeatable measurements.
- Appropriate equipment.
- Transparent methods.
- Independent analysis.
A single unusual reading may be interesting, but repeated and independently verified results carry greater significance.
Limitations of environmental evidence
Environmental evidence has limitations.
These include:
- Measurements may be affected by surroundings.
- Equipment may produce false readings.
- Conditions may change naturally.
- Results may be difficult to reproduce.
- Interpretation may exceed the available data.
A measurable anomaly does not automatically identify its cause.
Environmental evidence and evidence ratings
Within The Vault, environmental evidence is assessed alongside other available information.
Factors include:
- Measurement reliability.
- Equipment quality.
- Documentation.
- Controls used.
- Repeatability.
- Independent verification.
- Alternative explanations.
Environmental evidence may contribute to an evidence assessment but is rarely considered conclusive without additional supporting evidence.

Writing guidelines
When describing environmental evidence, articles should separate measurements from interpretations.
Preferred:
"Investigators recorded an unusual temperature change during the investigation."
Avoid:
"Investigators recorded a ghostly cold spot."
Preferred:
"The cause of the reading remains unexplained."
Avoid:
"The reading was caused by paranormal activity."
unless supported by appropriate evidence.
