Earthquake Hazard Maps & Liquefaction: Alaska emphasis
TOTLE (Teachers on the Leading Edge), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), EarthScope ANGLE, and ShakeAlert projects
Ground shaking is the primary cause of earthquake damage to man-made structures. This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment. The amplitude of ground shaking is affected by the type of near-surface rocks and soil. Earthquake ground shaking can cause even gently sloping areas to slide when those same areas would be stable under normal conditions. Liquefaction is a phenomenon where water-saturated sand and silt take on the characteristics of a dense liquid during the intense ground shaking of an earthquake and deform. Includes Alaska and San Francisco examples.

Build a Better Wall
FEMA (Federal Emergency Management Administration) and CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program). Improvements by ShakeAlert.
How can we design buildings to withstand an earthquake? This activity uses simple materials and gives learners a chance to experiment with structures that can withstand an earthquake. Two optional activities explore building damage by subjecting models to ground vibration on a small shake table.

Calculating and using Unit Hydrograph using Matlab

We are using the concept of Unit Hydrograph to understand the behavior of a watershed following a rain event and to calculate the runoff following any rainfall event.
