Earthquake Machine
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
In this activity, learners work collaboratively in small groups to explore the earthquake cycle by using a physical model. Attention is captured through several short video clips illustrating the awe-inspiring power of ground shaking resulting from earthquakes. To make students' prior knowledge explicit and activate their thinking about the topic of earthquakes, each student writes their definition of an earthquake on a sticky note. Next, through a collaborative process, small groups of students combine their individual definitions to create a consensus definition for an earthquake.

Unit 1: Earthquake!
Vince Cronin, Baylor University (Vince_Cronin@baylor.edu) Phil Resor, Wesleyan University (presor@wesleyan.edu)
In this opening unit, students develop the societal context for understanding earthquake hazards using as a case study the 2011 Tohoku, Japan, earthquake. It starts with a short homework "scavenger hunt" ...

Earthquake Intensity
Jennifer Pickering
Introductory lesson that compares ShakeMaps between earthquakes in the same location but different magnitudes, and earthquakes of the same magnitude but different depths, to acquaint learners to the fundamental controls on intensity of shaking felt during an event: magnitude and distance from the earthquake source.

Base Isolation for Earthquake Resistance
Larry Braile (Purdue University) and TOTLE (Teachers on the Leading Edge) Project
This document includes two activities related to earthquake base isolation. Learners explore earthquake hazards and damage to buildings by constructing model buildings and subjecting the buildings to ground vibration (shaking similar to earthquake vibrations) on a small shake table. Base isolation a powerful tool for earthquake engineering. It is meant to enable a building to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. The buildings are constructed by two- or three-person learner teams.

Earthquake Seismograms and Spreadsheets
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students read and interpret seismograms, determine the epicenter of an earthquake by triangulation, and learn how to enter ...

Engaging With Earthquake Hazard and Risk
Jennifer Pickering
This introductory activity engages learners in the study of earthquake hazards and the risk these hazards pose to humans in the communities in which we live. Learners will compare three maps of Anchorage, AK, depicting spatial information related to seismic hazards to generate questions about the factors that influence shaking intensity and damage to the built environment during earthquakes.

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.

Pasta Quake: Exploring Earthquake Magnitude
Paul Doherty (Exploratorium Teacher Institute) and Roger Groom (Mt Tabor Middle School) with improvements by ShakeAlert
This short activity provides an intuitive introduction to earthquake magnitude using an everyday item--spaghetti. Learners are introduced to the earthquake magnitude scale by breaking different amounts of uncooked noodles. Visual scale of the pasta emphasizes the relative differences between magnitudes with each whole step in magnitude. For older students, the demonstration helps students understand why seismologists use the nonlinear logarithmic scale to best graph the huge range of quantities.

Signal processing and earthquake triggering
Jackie Caplan-Auerbach, Western Washington University
In this exercise, written for an undergraduate seismology class, students use MATLAB to analyze waveforms from the 2004 Sumatra M9.0 earthquake, as they were recorded on three seismic stations in Alaska. Two of ...

Alaska Earthquake Hazard Inventory & Mitigation Planning
Bonnie Magura (Portland Public Schools), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), and ANGLE Project
In this two-part activity, students/participants first: - Complete a Hazard Inventory for their city or area of interest in the event of a magnitude 7 or larger earthquake and tsunami. - Identify what critical structures and infrastructure will be affected. Then: - Write a summary statement assessing strengths and vulnerabilities of essential services or infrastructure. - Propose actions for mitigating vulnerabilities. - Create an Action Plan to address identified needs.
