"Design an earthquake-resistant, modular shelter system composed of lightweight, stackable units with clean, modern lines. Each unit should be compact but adaptable, with foldable walls and extendable spaces to accommodate families of different sizes. The shelters should be arranged in clusters around a central community area, featuring minimalistic but functional outdoor spaces. Visualize the structures on a flat terrain, with a mix of rigid, earthquake-dampening materials like steel frames and lightweight panels. Architectural presentation techniques like exploded axonometric views, sectional perspectives, and plan layouts should be used to clearly show the modular assembly and spatial organization. Highlight flexibility and community interaction, using transparent or semi-transparent materials for certain sections to reflect openness and accessibility."
