Seismograph Trace in Algiers School Gym

Soft, diffused light from a post-rain noon filters into the Algiers school gymnasium, illuminating a portable seismograph case resting on a folding table. A continuous paper trace curls upward from the machine, its black ink line marking subtle ground vibrations against the white background. The gym floor reflects the damp air, showing scattered water droplets from the light drizzle. Behind the instrument, rows of empty bleachers stretch into the distance, their metal frames gleaming under the flat glare. The symmetrical arrangement centers the device, showing the precise analytical calm of the moment. A final ink line curves sharply at the paper's edge, showing the exact moment of seismic activity.
