Case No. #1066
Atlantic Forest, Deep Low-Frequency Pulsation
Summary
In the early hours of March 12, 2018, an unknown ultra-low-frequency vibration was first recorded deep within Brazil's Atlantic Forest. Ground sensors deployed by an environmental research team detected rhythmic pulsations distinct from natural phenomena. This phenomenon closely resembles local indigenous legends of a 'forest heartbeat,' yet attempts by authorities to investigate have been met with equipment malfunctions and personnel health issues. The source of the vibration remains unidentified, unclassifiable by known biological, geological, or artificial factors. The Bureau maintains ongoing surveillance to decipher the phenomenon.
Details
On March 12, 2018, deep within the Atlantic Forest of Brazil, a specific low-frequency vibration was recorded for the first time. Ground sensors deployed by an environmental research team detected intermittent ultra-low-frequency sound for approximately three hours, starting at 02:17 AM. The vibrations were distinctly different from natural phenomena patterns, suggesting a kind of organized pulsation. The detected frequency band fluctuated between 2Hz and 8Hz, and its regularity did not align with tectonic movements.
This phenomenon aligned with ancient narratives among the indigenous Copai people, who speak of the 'Heart of the Forest.' They have passed down stories of 'earth's heartbeat' emanating from deep within the forest during certain periods, often associated with illness or poor harvests. Historical records indicate multiple similar reports in the same region in the 1970s, which were then attributed to geological activity or unknown animal calls. However, the current vibration's frequency band is unusually low for a biological sound, and too regular for geological activity.
Authorities dispatched multiple survey teams equipped with high-sensitivity microphones, ground-penetrating radar, and thermal imaging drones. However, attempts to pinpoint the phenomenon's core were consistently obstructed. Electronic equipment frequently malfunctioned or experienced rapid battery drain when approaching the suspected source. Specifically, high-precision acoustic measurement devices repeatedly reported temporary shutdowns.
Furthermore, vibrations observed at specific points exhibited a localized nature, undetectable at other locations, complicating the identification of a physical source. The area where the vibration was strongest was limited to a diameter of approximately 50 meters, decaying rapidly further away. This localization suggests the source is either very small or highly directional, but its true nature remains unknown.
Some team members reported disorientation and mild nausea when approaching the sound source, experiencing temporary, unexplained health issues. These symptoms are similar to those known to be caused by low-frequency sounds affecting the human body, but the intensity required to cause them would be far beyond typical acoustic levels. The team leader testified experiencing a sensation of 'profound silence' accompanied by a feeling of heaviness when in close proximity.
Recognizing the gravity of the incident, the Ministry of Environment formed an additional expert team, but without success. Geologists, biologists, and acoustic engineers conducted field investigations but reported the phenomena as inexplicable within their respective scientific frameworks. There was a consensus that existing scientific paradigms could not clearly categorize this phenomenon.
To date, the source of this low-frequency vibration remains unidentified. The Bureau's analysis concludes it is an event with unique physical characteristics, fitting neither known animal species, geological phenomena, nor artificial sources. The Bureau hypothesizes this is either the activity of an unidentified life form or an unknown physical phenomenon.
Periodically, the vibration continues to occur, each time bringing subtle changes to the surrounding ecosystem. Animal herds exhibit avoidance behavior in the specific area during certain periods, and slight biases in plant growth patterns are observed. This incident remains under continuous surveillance as a priority investigation target for the Bureau.

Witness Testimony
Investigator AEntering deep into that forest, I was struck by a strange sensation, like a vibration beneath my skin. I couldn't hear it, but I felt something with my whole body. It was as if the ground itself was alive. The closer I got, the more nauseous I became.
Copai ElderSince ancient times, there are times when the forest's heart beats. It is the sound of the earth breathing deeply. We do not approach. When the earth speaks, people listen in silence. It is not a sound of joy.
Acoustic Engineer SOur high-sensitivity microphones ceased functioning when we neared the source. Unbelievable. Battery levels were full, yet they shut down as if their power was drained. Instruments failing to capture anything—this is a first.
Kyuu's Analysis
Inexplicable by known physics. The unique vibration affects the environment. Further deep-layer exploration is imperative.
