Item #: SCP-2704
Object Class: Euclid
Special Contaiment Procedure: All instances of SCP-2704 within Foundation custody are to be kept in storage containers located at storage hangar 19A and 19B. Infrasonic detection systems are to be placed within both storage units and kept operating at all times. If a sound at a frequency below 20 Hz is detected in either of these units, all personnel are to evacuate to Observation Site 19A, and are to remain there until the sound diminishes.
Instances of SCP-2704 discovered outside of Foundation custody are to be immediately reported. If said instances are located in a heavily visited or populated location, they are to be replaced by a 1:1 replica. This is necessary due to SCP-2704's current importance in modern Costa Rican culture. Instances found in their original position prior to SCP-2704’s discovery, as well as instances which reside in the Finca 6 archaeological site, are not to be relocated. Implanted Foundation agents have acquired control over administration and security of this site. Infrasonic detection systems are to be kept within all security offices of Finca 6. If a sound at a frequency below 20 Hz is detected, any present pedestrians are to be evacuated to a distance of 92 meters from the premises.
All subjects affected by an activated instance of SCP-2704 are to be apprehended and questioned. Class A amnestic are to be administered to all unnecessary subjects.
Description: SCP-2704 is the collective designation given to an assortment of over three hundred petrospheres predominantly located in Costa Rica, which were initially discovered in the Diquis Delta during the 1930s. These spheres range in size from a few centimeters to over 2 meters in diameter, and weigh up to 16 metric tons.
The anomalous effects of SCP-2704 instances only become activated when they are paralleled with a specific celestial body. This occurs primarily with the planets and moons of our solar system. However, there have been incidents which may have involved celestial bodies outside the milky way galaxy. It is believed that SCP-2704 instances activate in concordance with one another depending on their arrangement, however it is impossible to predict when the majority of instances will become activated, due to the loss of their original organization during initial discovery. Studying the activation of these unorganized instances has not progressed the discovery of a pattern of activation.
Once any instance of SCP-2704 is activated, it will begin to emit a sound at a pitch of about 13 Hz, undetectable by the human ear. This hum has physical and psychological effects on all human beings within a 92-meter radius, and plays continuously for approximately 3 hours after activation. The means used to produce this sound remain unknown, as well as the nature of their activation.
• After 30 minutes of exposure subjects experience mild migraines and discomfort.
• After 1 hour of exposure subjects experience increase in emotional unease and throbbing pain in the temple.
• After 2 hours of exposure migraines worsen, in some cases subjects become incapacitated due to pain. Subjects will begin to receive an influx of information. Complimenting this information, subjects experience visual and auditory hallucinations. This information, as well as the hallucinations, are described as disjointed and unorganized. This activity lasts for approximately one hour. These episodes can cause loss of consciousness in those with a history of medical complication or recent head injury. If these subjects are not removed from exposure radius, they may enter a coma. However, casualties from exposure are rare.
• After 3+ hours of exposure, effects will slowly deteriorate. Subjects retain memories of some information received during incident, but the majority is reportedly forgotten.
Please refer to the Incident Log for further details concerning the effects of SCP-2704 and information received.
These spheres were originally found in clusters of up to twenty organized in geometric patterns. They are estimated to have been carved between 200 BC and 1600 CE. Details concerning the method used to sculpt and transport these spheres, as well as their original purpose, are unknown. This is due to the extinction of the indigenous culture of Diquis Delta following the Spanish conquest.
The anomalous properties of SCP-2704 were not discovered by the Foundation until 1947. Due to this, the majority of known instances have been damaged and re-positioned prior to Foundation involvement. These instances of SCP-2704 were relocated to public areas such as tourist locations, , government offices, and several museums, as well as private properties and homes. The majority of these instances have been replaced with exact replicas, and are now under Foundation custody. However, there are still public instances of SCP-2704 that have yet to be located, as well as instances in their original position which remain undiscovered.
Known instances which retain their original order are primarily located in the Finca 6 archaeological site. These instances of SCP-2704 are to remain in this original position to facilitate the observation of activation, discovery of patterns of activation, and investigation of the stone's possible purpose. Public access to these spheres has been scheduled and restricted in order minimize possibility of pedestrian presence during a cluster activation. Since initial containment there has only been one successfully recorded cluster activation. For further details concerning effects of a cluster activation please refer to the Finca6 incidents.
On █/██/19██ undercover field agent Marcelo Ocampo reported single sphere activation at 12:50 outside Costa Rican Center of Science and Culture. ██ pedestrians were affected before Foundation interference. Local task force dispatched to evacuate office building and apprehend all effected parties.
At 2:30 pm on █/██/19██ an unknown number of SCP-2704 instances located in storage hangar 19b became activated. This incident occurred prior to the placement of a infrasonic detection system in storage hangar 19b, causing the exposure of 13 members of personnel. Surveillance cameras depict subjects undergoing mild to severe seizures, resulting in 3 casualties. Surviving personnel report hallucinations and migraines similar to those of public incidents, but at a much higher intensity. Investigation suggests this is due to subjects being exposed to many activated unorganized instances at once.
At 1:30 am on █/██/20██ a group of five spheres began to emit an audible hum at a pitch of 20 Hz. Unlike the activation of a single SCP-2704 instance, the effects of this activation were immediate. All human beings within a 92-meter radius entered a state described similar to intoxication. Surveillance depicts many of the subjects seating themselves around the spheres in a semicircular formation. This activity continued for an approximated 7 hours. All members of personnel present, as well as Finca-6 security officers and pedestrians were interviewed after the incident. The following is an interview with agent Daniel Vega.
Contact has been made with Franklin Chan Diaz concerning the incomplete blueprints. Due to his experience as an engineer and current research in the facilitation of space travel, it was believed there existed a connection between him and the information provided by Agent Vega. Dr. Diaz expressed great interest in the blueprints, implying that they had several similarities to experimental designs he has been working on for his current study of plasma propulsion. Dr. Diaz suggested the incomplete blueprints were that of a section of an exceedingly advanced plasma propulsion rocket engine, and that such a device would theoretically cause significant advances in interplanetary travel, as well as be used as a platform to begin studies of interstellar travel. However, human knowledge of this technology is currently insufficient to complete these designs. Dr. Diaz was administered Class-A amnestic after his analysis.
Current theory presented by Dr. Quesada suggests that the purpose of these blueprints is to assist in the progress of human space exploration, specifically that of the dwarf planet Eris, which has yet to be visited by a spacecraft. However, it is currently impossible to make use of this information due to it being incomplete.
At 9:23 pm on ██/██/20██ a single sphere began to emit an audible hum at a pitch of 23 Hz. The activation of this sphere has been determined to be caused by it's alignment with the dwarf planet Eris. All human beings within a 92 meter radius of the activated instance entered a state similar to that of Incident Finca6-1. However, the severity of the effect diminished with the distance from the sphere. Agent Gabriel Chavez, who was located 2 meters from the sphere during activation, was the only subject to undergo a complete hallucinatory episode. The following is an interview with Agent Chavez after the incident
