Saudi Arabia, Harrat Rahat: 'Silent Pulsator' Subterranean Movement Incident
Summary
In the early hours of September 13, 2019, in Harrat Rahat, a vast basalt plateau in western Saudi Arabia, unusual low-frequency sounds and a massive shadow moving beneath the ground were observed multiple times. Reports of an unidentified creature, which Bedouin nomads call "The Pulsation of the Earth," surged, leading to the deployment of an investigation team. This phenomenon exhibits patterns distinct from geological shifts and has been confirmed to interfere with observation equipment. The authorities cannot rule out the possibility of an unknown ecosystem deep beneath the desert or an unresolved physical phenomenon.
Details
At 03:15 on September 13, 2019, peculiar low-frequency vibrations originating from beneath the basalt surface of Harrat Rahat in western Saudi Arabia were intermittently recorded by nearby meteorological observation stations. Simultaneously, approximately 20 km away, an oil exploration team driving through the area witnessed a massive dark shadow, dozens of meters long, seemingly gliding over a sand dune crest. The shadow vanished instantly, after which the exploration vehicle's GPS system experienced a temporary malfunction, and its compass pointed in an aberrant direction.
A few days later, at 01:40 on September 16, Bedouin nomads traversing the same region experienced a deep, heavy rumbling sound emanating from the ground and a phenomenon where the sand significantly undulated. They traditionally refer to this phenomenon as "Al-Nabbada" (the pulsator), recognizing it as a sign of a colossal entity residing deep within the desert. Some testimonies also reported fleeting reddish points of light appearing in the darkness of night, seemingly synchronized with the shadow's movement.
In response to these reports, the authorities formed a joint investigation team, deploying geologists and biologists to the site. Extensive acoustic measurements detected infrasound frequencies below the human hearing range in multiple locations. These frequencies exhibited irregular patterns inexplicable by known geological activity or meteorological phenomena, resembling the acoustic patterns of large marine creatures but on an incomparably grander scale. Furthermore, shallow indentations, not strictly linear but continuous and approximately 5 to 8 meters wide, resembling pressure marks, were discovered on the surface.
Subsurface sensors installed by the investigation team irregularly captured data indicative of large-scale mass movement. This movement involved a complex path through deep bedrock layers, clearly distinct from geological shifts such as groundwater flow or landslides. The sensors also recorded patterns where the moving entity would temporarily halt at specific points before resuming its movement.
This incident also raised the possibility of a connection to the region's geological characteristics, particularly the subsurface structure of Harrat Rahat, where active volcanic traces remain. However, the dynamic nature of the recorded phenomena and their extensive interference with electronic devices are difficult to explain by mere geothermal activity or magma movement. The estimated size of the "Pulsator" from the observed shadow length and subterranean mass movement data is vastly disproportionate to any known terrestrial creature, and its speed and ability to burrow through sand also defy conventional understanding.
To date, the identity of this "Silent Pulsator" remains unconfirmed. Its location and scale subtly shift with each sighting, making it difficult to establish a specific pattern. Tracking it in the vast desert environment proves extremely challenging, and the authorities continue their monitoring and data collection to determine whether this phenomenon represents an endemic unidentified creature or an unresolved phenomenon in earth science.

Witness Testimony
Oil Exploration Team Leader"The desert ridge distorted unnaturally, and something moved beneath it as if gliding. It was immense, yet almost silent. Our instruments went haywire temporarily, and the compass was off."
Bedouin Nomad A"At night, a deep rumbling came from the ground. The sand undulated like the sea. A sign of 'Al-Nabbada,' as my grandfather told me. It is a creature that crawls beneath the earth."
Geologist (Anonymous)"The detected infrasound differs from minute plate movements or volcanic tremors. If hypothesized as the activity of a specific life form, it possesses an abnormal scale, unlike any known creature."
Kyu's Analysis
Inexplicable by known ecosystems. A presence lurking deep within the desert, mimicking geological activity. This incident is highly significant. Continuous monitoring is imperative.
