Rainfall Sandbox vs Terramoto

Ever wondered how rainclouds and land impact each other? Why does one side of a mountain seem greener than the other? Build your own world and test out different scenarios to get to the bottom of these questions and discover the secret of orographic lift! Rainfall Sandbox is an engineering simulation where players can choose between various land and water formations to create their own geosphere. Observe how rainclouds form, see where they go, and witness how your landscape changes! * Aligned to educational science standards for third to fifth grade * Grounded in educational psychology research * Sandbox design dynamically simulates the scientific phenomena of orographic lift * Designed for play and discovery-based learning * Introduces students to concepts such as orographic lift, and geosphere, atmosphere, hydrosphere and biosphere interactions * Fully standalone learning experience * Designed to be used with SSEC Science for the Classroom Curriculum

Terramoto brings the science of earthquakes and tsunamis to life with stunning real-time physics simulation. DISCLAIMER This app is for educational and entertainment purposes only. Terramoto is NOT an emergency warning system and should NOT be used for disaster planning, evacuation decisions, or any life-safety purposes. The simulations are simplified models that do not account for all real-world factors. For actual tsunami warnings, always rely on official sources such as NOAA, local emergency management agencies, and government alerts. REAL PHYSICS, NOT ANIMATIONS Unlike simple visualizations, Terramoto uses actual shallow water equations—the same mathematics used by scientific institutions—to simulate how tsunami waves propagate across oceans. Watch waves travel at realistic speeds, reflect off coastlines, and flood coastal areas based on real elevation data. GPU-ACCELERATED SIMULATION Powered by Metal compute shaders, Terramoto runs a full fluid dynamics simulation on your device. The well-balanced hydrostatic solver ensures physically accurate wave behavior without artificial artifacts. GLOBAL COVERAGE Accurate coastlines from Natural Earth public domain data Real bathymetry (ocean depth) affecting wave speed and behavior Waves travel faster in deep ocean, slow and amplify in shallow coastal waters AFFECTED CITIES ANALYSIS See which cities would be impacted by seismic events. Terramoto calculates distances and provides estimates based on magnitude and proximity. FEATURES Tap anywhere on the map to simulate earthquakes of varying magnitudes Watch tsunami waves propagate in real-time across the globe Observe wave reflection, refraction, and coastal flooding Track simulation time and wave progression Smooth, interpolated wave visualization Dark mode interface designed for clarity EDUCATIONAL VALUE Perfect for students, educators, and anyone curious about geophysics. Understand why some coastlines are more vulnerable to tsunamis, how ocean depth affects wave speed, and why early warning systems are critical.
