Top-down orthographic view (strictly from above) of a volcanic mountain belt strip designed as a map overlay. A long curved ridge line made of dark rocky mountains, with several small volcano cones along the strip. Bright red-orange lava cracks and glowing magma seams running through the ridge, symbolizing a tectonic plate boundary and magma being pushed upward. Clean infographic style, sharp silhouette, high contrast, minimal details, no perspective, no depth tilt, no horizon. Isolated single object centered on a pure white background (#FFFFFF).
