Case No. #1574
Ecuador, Pastaza Province: "Whispers of the Abandoned Waterway" Infrasound Anomaly
Summary
In the early hours of July 12, 2023, near Mera, Pastaza Province, southeastern Ecuador, reports emerged of anomalous infrasound emanating from an abandoned colonial-era stone waterway. The sounds, described as deep groans or faint whispers, caused intense unease and disorientation among local residents. Initial investigations by authorities failed to pinpoint the source, ruling out natural phenomena or known biological activity. The sounds occur irregularly, becoming particularly pronounced at night and in humid conditions.
Details
On July 12, 2023, authorities received multiple reports from residents of Mera, Pastaza Province, concerning an unknown low-frequency sound near an abandoned colonial-era waterway located on the outskirts of the village. This waterway, extending deep into the rainforest, is currently disused but has been subject to local legends as a "place where the souls of lost workers reside." Residents described the sounds as "groans echoing from the depths of the earth" and "incomprehensible whispers," with some reporting tinnitus, headaches, and psychological distress.
Authorities immediately formed and dispatched an investigation team to the site. During the initial survey, attempts to identify the sound source using specialized frequency analysis equipment yielded no specific origin. However, recording devices set up by the team captured irregular sound fluctuations in the infrasound range, below human audibility. Although these fluctuations lacked a distinct pattern, they occasionally exhibited undulations resembling faint vocal signals.
Local elders testified that this phenomenon closely resembled legends passed down through generations. These tales recount workers who perished under harsh conditions during the waterway's construction, their souls now said to linger within it. Past attempts to repurpose the waterway have consistently failed due to frequent worker illnesses and inexplicable accidents. This information presents an eerie congruence that cannot be dismissed as mere superstition.
Authorities established an extensive acoustic sensor network, conducting continuous monitoring over several weeks. This revealed that the infrasound occurred at unpredictable intervals, becoming particularly prominent from late night to early morning, and in high humidity environments. However, recorded data frequently suffered inexplicable omissions, and some sensors exhibited unexplained malfunctions.
During one nocturnal investigation, a team member on site suddenly reported severe dizziness and nausea, then lost consciousness. Another investigator claimed to have heard auditory hallucinations of multiple voices echoing from deep within the abandoned waterway, but no audio was recorded during this incident. These occurrences are abnormal and cannot be explained by mere environmental factors or equipment failure.
Detailed acoustic analysis suggested that some recorded infrasound contained waveform patterns similar to human vocal cord movements. However, this audio did not constitute language and was merely a collection of fragmented, meaningless sounds. It presented as if inexpressible emotions or thoughts had materialized as sound.
Currently, the area around this abandoned waterway is strictly restricted by authorities. The unexplained acoustic phenomenon continues to occur irregularly. Authorities deem this incident an unsolved anomaly that cannot be explained by ordinary natural phenomena or psychological factors.

Witness Testimony
Witness A (Mera Village Resident)When I woke up in the middle of the night, I heard a low groan, like it was crawling up from deep underground. At first, I thought it was the wind, but it wasn't. It sounded like... something pleading.
Witness B (Mera Village Resident)I've heard that waterway has always been strange. Whenever someone tries to work on it, bad things happen. The voices, I think they're the deceased trying to return home.
Investigator C (Acoustic Analysis Specialist)Within the low-frequency noise, there were clearly fluctuations in a frequency band close to human speech. However, it wasn't distinct language. It felt as if deep sorrow or anger was leaking out as sound.
Kyu's Analysis
Residual emotions, or a different intent? This acoustic phenomenon transcends physical laws. Continued recording and long-term analysis are imperative.
