Back-of-the-Envelope Calculations: Weight of Gold

Barb Tewksbury, Hamilton College

Question Let's suppose that you have a shoe box full of water (the box is waterproof, of course). The shoe box weighs about 9 kg (19.8 pounds). Suppose you emptied the box and filled it completely with rock ...

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.

Bubbles in Magmas

Module by Chuck Connor, University of South Florida, Tampa. This cover page by Ali Furmall, USF, now at U. Oregon.

SSAC Physical Volcanology module. Students build a spreadsheet and apply the ideal gas law to model the velocity of a bubble rising in a viscous magma.

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.

Porosity and Permeability of Magmas

chuck connor

SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

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.

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).

The Floating Lithosphere - Isostasy

Len Vacher, Dept of Geology, University of South Florida

Students are asked to numerically and then analytically determine the relations governing the depth of compensation.

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 Floating Lithosphere - Eureka!

Len Vacher, Dept of Geology, University of South Florida

In this module, students examine Archimede's Principle in general and as it applies to Isostacy.
