SCP-654

Item #: SCP-654

Object Class: Euclid

Special Containment Procedures: SCP-654 is currently contained in an isolated area of a large coastal national park, approximately 250 km from the nearest city. Large quantities of low income housing units have been demolished and cleared away from the area, and possibly replaced with new structures. SCP-654 is to be protected by a 5 km radius around its location at all times, and any trespassers are to be apprehended immediately by security personnel.

Due to excessive losses of life due to SCP-654's effect, it is strongly recommended that civilians not enter the area within the containment perimeter.

Description: SCP-654 is a large, irregularly-shaped block of Portland cement with a well-defined circular perimeter. Within the perimeter is an area in which Earth has been removed, providing a clear path around the object. The effect of SCP-654 originates from within this 'void' area and cannot be seen on a scale greater than 1 m unless the person viewing is at least 10 m away. It is theorized that SCP-654 was originally used to build roads around the perimeter, although there is no concrete evidence supporting this theory.

When an individual enters SCP-654's containment zone and approaches very close to the center of its surface, they will suddenly begin to feel as if they are moving at high speeds through the ground. While this feeling can be brought up to approximately 80 km per hour, outside of SCP-654's containment zone, individuals who approach it at this speed experience nothing out of the ordinary. It is currently unknown exactly how long subjects will remain in their motionless state after entering SCP-654; records show that some subjects have remained motionless for periods exceeding two weeks.

Subjects who are within 20 m of the center of SCP-654's surface when this occurs begin to suffer from extreme visual disorientation and dizziness, often suffering from fainting spells and nausea. Particularly susceptible subjects may vomit frequently during this time, while violent physical reactions such as convulsions become more common as dosage increases. Subjects exposed to the side effects of SCP-654 will recover completely upon leaving SCP-654's containment zone or if removed from their sight. If a subject remains within SCP-654's containment zone after having entered it, they will begin to lose consciousness.

The exact formula for SCP-650's effect is not yet known; however, current research suggests that it is caused by Portland cement and/or silica sand containing trace amounts of sodium chlorate or sodium bicarbonate being mixed with water (maximum pH 6). Further research into these substances has been curtailed due to lack of funding.

Addendum-654-1: Incident Report

On ██/██/20██, security personnel reported a large amount of civilians entering the containment perimeter of SCP-654. After searching the area and finding no anomalies, they contained the group in a safe area and waited for foundation personnel to arrive. Reports indicate that approximately 20% of the civilians were suffering from gastric distress and had vomited prior to containment. Upon arrival, Foundation personnel scanned the area and located the source of SCP-654's effect.

Dr. ██████: Ah, I see you've found it!

Security Officer: Yeah, just outside the containment perimeter. I think we got it contained though.

Dr. ██████: Do you have a way to contain it?

Security Officer: We're not sure yet. We've got something blocked off here, but it's not quite big enough to cover the whole thing. The best I can do is keep it contained until we can get something bigger.

Dr. ██████: Alright. Go ahead and try to contain it as best you can, alright?

Security Officer: Will do sir. Shouldn't be a problem though, right? It's just cement?

Dr. ██████: Right. It's just cement. Just make sure you don't let anyone inside, okay?

Security Officer: Yes sir. We'll keep it contained as much as we can.
