The USGS Earthquake Hazards Program web site allows you to download earthquake data as an Excel spreadsheet from any area in the world over a specific time period and magnitude range. This is a fantastic resource that makes it possible to study any area you want and not be limited to canned data sets. It's also very easy to save the Excel files in a way that can be imported directly into ArcMap and then into ArcScene.

In this in-class activity, students download earthquake data from the Sumatra area and examine it first in Excel. They quickly observe that, even when they sort the spreadsheet in various ways, they can develop only a limited picture of the data. In the second part of the activity, students bring the data into ArcMap to portray it spatially, and they change the symbols to portray various attributes of the earthquakes. In the final part of the activity, students display the data in three dimensions in ArcScene. This latter is particularly powerful, because students can interactively rotate the ArcScene, which helps immensely in their abilities to visualize the depth distribution of quakes.

Although the activity focuses on Sumatra, the activity could easily be done for any area of the world. Later in the semester in this course, students download earthquake data from other areas in the world when they evaluate earthquake hazards in other regions.

You can also download a GIS Primer (Acrobat (PDF) PRIVATE FILE 1.2MB Mar30 10) that we have written, which is a simple GIS "how-to" manual for tasks including those used in this exercise.

This activity is a teacher-led demonstration of continental drift and includes a math worksheet for students involving the calculation of continental drift over time. Students will understand what continental drift is, why it occurs, and how earthquakes occur because of it.

CK-12 Earth Science For High School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.

CK-12 Earth Science For Middle School covers the study of Earth - its minerals and energy resources, processes inside and on its surface, its past, water, weather and climate, the environment and human actions, and astronomy.

The earthquake game teaches how scientists learn about real earthquakes. The player must learn about S& P waves and triangulation to determine the epicenter of the earthquake that hit the cities.

To focus their research, students are presented with the following hypothetical situation:
Suppose you and your classmates are members of an organization that is looking for a site to build a new headquarters. As the Society for Earthquake Enthusiasts (SEE), you plan to put your headquarters at the site of a historically significant earthquake. You are not looking to put yourselves at risk, however, and are therefore looking for a safe location. You have decided that a safe site is one that will not produce a deadly earthquake in your lifetime (i.e., in the next 80 years).

Students complete a series of assignments throughout the semester to demonstrate their understanding of structural geology by writing papers and giving an oral presentation. First, a letter proposing a site is due early in the semester, next a historical background paper is due mid-semester, and finally a persuasive report and oral presentation are due at the end of the semester.

Students work in a jigsaw format, they start in an expert group analyzing one particular aspect of the earthquake that occurred (e.g., tsunami, geologic maps, damage assessment). After analyzing the data/information provided, students get into their new groups, which are a "consulting team" to make recommendations to key governmental officials about the earthquake they studied and implications for future development. These are presented in a poster session style event, which then leads to individual papers that are written about the same topic, which are peer reviewed and revised. Students are asked to reflect on their strengths and weaknesses in the process and to consider changes for future opportunities, as well as connect the curriculum to the overall process of science.

Students will write a research paper comparing the Sumatran (2004) and Tohoku (2011) tsunami generating earthquakes.

This demonstration uses an "earthquake machine" constructed from bricks, sand paper, and a winch, to simulate the buildup of elastic strain energy prior to a seismic event and the release of that energy during an earthquake.

This hands-on demonstration illustrates how GPS instruments can be used in earthquake early warning systems to alert people of impending shaking. The same principles can be applied to other types of early warning systems (such as tsunami) or to early warning systems using a different type of geophysical sensor (such as a seismometer instead of a GPS).This demo is essentially a game that works best with a large audience (ideally over 30 people) in an auditorium. A few people are selected to be either surgeons, GPS stations, or a warning siren, with everyone else forming an earthquake "wave."

Students in groups of two are giving access to 3 component seismograms from four locations through Google Earth. They are then asked to pick the P-wave and S-wave arrivals using OneNote and convert the time lag into a distance to epicenter. A circle drawing application in Google Earth then allows them to plot possible locations for the earthquake epicenter. This activity gives students practice in interpreting data, analyzing uncertainty and error in data or data analysis, and peer teaching Uses online and/or real-time data

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.

In this activity, students explore of the concept of probability and the distribution of earthquake sizes, and then work to understand how earthquake hazards are described by probabilities. Students then work in small groups to collect and analyze data from a simple physical earthquake model and use online data to investigate and compare the earthquake hazards in California and Missouri. The activity concludes with a reflection where they students are asked to consider how, in the role of a city planner or emergency manager, they would use what they have learned to mitigate the earthquake hazard in California and Missouri.

Earthquake location is an interesting and significant aspect of seismology. Locating earthquakes is necessary for compiling useful seismicity information, calculating magnitudes, and study of fault zones, Earth structure and the earthquake process. Methods of earthquake location involve understanding of seismic waves, wave propagation, interpretation of seismograms, Earth velocity structure, triangulation, and the concepts (and mathematics) of inverse problems. Because earthquake location can be approached with relatively simple to very complex methods, it can be included in various levels of educational curricula and for "in-depth" study. Progressively developing a deep understanding of concepts, computational techniques and applications (and the capabilities, limitations and uncertainties of these applications) is a characteristic of science and an -- opportunity to "learn science by doing science." A number of methods that vary from simple to complex are available for learning about earthquake location. The methods also allow connections to other important concepts in seismology and provide a variety of approaches that address different learning styles and can be used for reinforcement and assessment.

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.
