Summary

On April 11, 2018, a phenomenon of periodic outgassing of an unknown black liquid from the ground was confirmed deep within the forests of the Upper Rio Negro Basin, Amazonas, Brazil. This liquid induces abnormal metamorphosis in surrounding plants, rapidly discolors them, and leads to their demise. Local indigenous communities refer to it as "Tears of the Earth," a phenomenon known through ancient traditions. Investigations by authorities have recorded inexplicable electromagnetic field fluctuations and subtle acoustic noise at the outgassing site. The outgassing continues to this day, with its origin and mechanisms entirely unclarified.

Details

On April 11, 2018, reports emerged of a specific location deep within the remote forests of the Upper Rio Negro Basin, Amazonas, Brazil, where a black, viscous liquid periodically outgasses from the ground. These reports were relayed to authorities by indigenous communities who have resided in the region for many years. Plants exposed to the outgassed liquid exhibited abnormal metamorphosis, rapidly discoloring and ultimately dying completely.

Authorities, in cooperation with the National Institute of Amazonian Research, immediately dispatched an investigation team. Initial reconnaissance observed that the muddy soil within an approximate 3-meter radius was saturated with the black liquid, which intermittently outgassed from its center. Elders of the indigenous communities call this phenomenon "Yurupchá" (Tears of the Earth) and have passed down traditions of its periodic occurrence in that land since ancient times.

Collected liquid samples underwent detailed chemical analysis at the institute. However, their composition did not match any known terrestrial substance, revealing unusually high concentrations of unknown organic compounds and amorphous inorganic matter. This substance was found to induce simultaneous abnormal proliferation and breakdown in surrounding plant cells at an accelerated rate.

Electromagnetic field measurements at the outgassing site recorded periodic fluctuations in the electromagnetic field starting several minutes before active outgassing. Simultaneously, extremely faint low-frequency acoustic noise, imperceptible to human hearing, was also detected. While these physical changes are presumed to be closely related to the outgassing itself, their causal relationship remains unclear.

During the investigation, portable electronic and communication devices periodically suffered unexplained malfunctions in the vicinity of the outgassing site. Specifically, data recording devices experienced sudden data loss, and cameras recorded abnormal noise on multiple occasions. This suggests the possibility that localized electromagnetic field anomalies affected the equipment.

Analysis of past satellite imagery confirmed a pattern of periodic vegetation changes around the site over several-year cycles. At certain times, circular or elliptical areas of discolored vegetation appeared, gradually recovering thereafter but never fully returning to their original state. This periodicity aligns with the outgassing events.

Authorities are considering the possibility that this phenomenon is caused by geological activity, unknown microbial activity, or even more anomalous factors. However, current scientific knowledge cannot provide a comprehensive explanation for the liquid's origin, its effects on plants, or the accompanying electromagnetic and acoustic anomalies.

This incident carries the potential to pose an unknown threat to the Amazonian ecosystem. Authorities recognize the need for a long-term monitoring program and additional deep drilling investigations to assess the widespread impact on the ecosystem. The phenomenon remains active to this day, its true nature still shrouded in mystery.

Timeline

  2. April 20, 2018Joint investigation team from authorities and the National Institute of Amazonian Research arrives on site. Initial observations and liquid sample collection.
  3. May 15, 2018Liquid analysis begins at the institute. Composition found to be unlike any known terrestrial substance.
  4. June 2, 2018Electromagnetic field and acoustic measurements commence at the outgassing site. Periodic anomalies recorded.
  5. Early July 2018Frequent malfunctions of investigation equipment. Data loss occurs.
  6. September 2018Analysis of past satellite imagery confirms periodic changes in vegetation.
  7. From 2019 onwardsTransitioned to long-term monitoring. The phenomenon continues.

Witness Testimony

Witness A (Indigenous Hunter)Deep in the forest, at that place, the earth weeps black tears. If touched, the leaves rot instantly. The elders have always told us never to approach it.
Investigator B (Researcher, National Institute of Amazonian Research)The liquid is highly viscous and unlike any common oil or mud. The analysis results were astonishing; nothing matched existing databases. Is this a new geological phenomenon, or perhaps...?
Investigator C (Authority-dispatched Technician)The electromagnetic field was abnormal, causing the measuring instruments to error repeatedly. Noise intruded at specific frequencies, and parts of the data sometimes vanished completely. It was as if we were being deliberately interfered with.

Kyu's Analysis

This phenomenon is unlikely to be natural. It suggests an unknown energy source deep within the earth. Continuous monitoring and deep drilling investigations are urgent.
