Geology Calculators
Geology calculators for volcanic plumes, ash hazards, earthquakes, rocks, sediment, and geophysical measurements used to reason about Earth systems.
Top calculators
A short starting set for the most common geology calculators workflows.
Earthquake Energy Calculator - Magnitude to Joules and TNT
Convert earthquake moment magnitude into radiated seismic energy, seismic moment and TNT equivalent, compare two quakes, and see why one step is about 32 times.
Richter / Local Magnitude (ML) Earthquake Magnitude Calculator
Estimate local (Richter) magnitude from Wood-Anderson amplitude and hypocentral distance with the IASPEI standard ML equation, plus a distance-sensitivity chart.
Rock Density Calculator – Calculate Density from Mass and Volume
Calculate rock density from mass and volume in grams and cm³. Useful for geology, mining, construction, and classroom lab work to compare rock and ore samples.
Boulder Weight Estimator - Approximate Rock Mass
Estimate the weight of an irregular boulder using its dimensions and rock density. Useful for landscaping, construction, and geology projects.
Enhanced Rock Weathering CO₂ Removal Calculator | Estimate Carbon Uptake from CaO and MgO Assays
Estimate CO₂ removal from enhanced rock weathering by entering rock mass, CaO and MgO content, and the fraction expected to react.
Geothermal Injection Seismicity Screening Risk Calculator
Screen a geothermal injection scenario with a transparent induced-seismicity score based on flow rate, pressure rise, fault density, prior M≥2 events, and distance to population.
