According to foreign media reports on January 17, residents of the Meteora community in West Thessaloniki, Greece, have been harassed by a mysterious underground voice for more than a month and have been sleepless all night. Locals say that since about December, mysterious sounds have emerged from the ground, making them feel very frightened.
Locals complain that deafening sounds can be heard every day from midnight to early morning, and curious urban explorers are now conducting a search to determine the source. A member of the Residents' Union of Meteora traveled to the intersection of Kifisias and the streets of the Acropolis, where he heard a continuous, rhythmically loud thud.
The closer he got to the ground, the louder he heard. Some netizens speculated whether it would be like the movie in which someone was secretly digging an underground tunnel at night. "Are they still playing Brave now?" A netizen asked. Another joked: "The Nephilis and the Hobbits came out." ”
The Meteora Residents' Union posted on Facebook that it had contacted local authorities to request an investigation. The local water company said that after preliminary investigation, the mysterious sound had nothing to do with the underground pipe. Kostas Papazachos, a professor of geophysics at Aristotle University in Thessaloniki, Greece, analyzed the audio, ruling out the possibility that it was a geological phenomenon.
Professor Papazajos said in an interview: "This is a rhythmic, periodic noise, not a precursor to an earthquake. It should be a human-induced sound, maybe a pump, a fuse, or a faucet, but it can't be a geological cause anyway. But worried residents said they could feel the ground moving with the noise, and some had moved out of fear. Now, the nearby streets have become a tourist attraction for urban explorers who flock there for hours, listening to the sounds and searching for sources. However, the latest inspections suggest that this may be related to the water pipe, but the investigation is still ongoing.
