What is the Volume of the 1992 Eruption of Cerro Negro Volcano, Nicaragua?
chuck connor
SSAC Physical Volcanology module. Students build a spreadsheet to calculate the volume a tephra deposit using an exponential-thinning model.

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber?
Module by Peter LaFemina, Penn State, State College, PA. This cover page by Ali Furmall, University of South Florida, now at University of Oregon.
SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.

Waves Through Earth: Interactive Online Mac and PC
JAVA Applet and activity provided by Visual Entities. Starting Point page organized by R.M. MacKay.
Students vary the seismic P and S wave velocity through each of four concentric regions of Earth and match "data" for travel times vs. angular distance around Earth's surface from the source to ...

The Waves and Tsunamis Project
Ralph Stephen
How is a tsunami like a wave on a string? We assemble rubber bands, paper clips and washers into strings with various mass distributions to observe the effects on wave characteristics. The project is supplemented ...

How are Flow Conditions in Volcanic Conduits Estimated?
chuck connor
SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

What is the Volume of a Debris Flow?
chuck connor
SSAC Physical Volcanology module. Students build a spreadsheet to estimate the volume of volcanic deposits using map, thickness and high-water mark data from the 2005 Panabaj debris flow (Guatemala).

How Do We Estimate Melt Density?
chuck connor
SSAC Physical Volcanology module. Students build spreadsheets to estimate melt density at high temperatures and pressures from the thermodynamic properties of silicates.

How Do We Estimate Magma Viscosity?
chuck connor
SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.
