Disclosed is an improved model kit including a plurality of support members for constructing a hollow frame upon which one or more surfaces can be constructed. The kit may include flat support members having slots, a first material which is in the shape of a flat sheet when fully extended, and which becomes self-adhering when saturated with water and which dries into a hardened material, a second material which becomes moldable when saturated with water and which dries into a hardened material, where the plurality of flat members are configured to interconnect with each other to form a hollow frame, where the first material can be laid over the hollow frame to form a first surface, and where the second material can be laid over the first surface to form a second surface. The improved model kit may be efficient, cost-effective, visually appealing, easy to assemble, and compact when stored.

A method can include providing a mesh of a geologic environment that includes conformable sequences and an unconformity; interpolating an implicit function defined with respect to the mesh to provide values for the implicit function; and identifying an iso-surface based on a portion of the values where the iso-surface represents the unconformity as residing between two of the conformable sequences. Various other apparatuses, systems, methods, etc., are also disclosed.

Disclosed is a real-scale landslide simulator for earthquake reproduction comprising: a base; a tower provided in one end of the base; a multi-stage simulation soil box provided movably in the vertical direction along the tower and filled with soil, which is subjected to compaction; a movable bogie provided movably in the horizontal direction on the upper surface of the base while supporting the other side of the multi-stage simulation soil box; a vertical reciprocator that reciprocates the multi-stage simulation soil box in the vertical direction; and a horizontal reciprocator that reciprocates the movable bogie in the horizontal direction. It is possible to reproduce liquefaction and shear strength reduction caused by an earthquake and analyze a real-scale landslide mechanism caused by an earthquake by repeatedly providing vertical and horizontal vibrations to the soil and forming a groundwater level using the groundwater simulation device.
