This week we have a guest columnist, Terry Smithson the Director of Marketing for JES & Co., covering the topic of earthquakes. Peggy will be back in a few weeks.
On October 17, 1989 at 5:04 P.M., I was in the upper deck at Candlestick Park in San Francisco for game 5 of the World Series. I had a childhood friend that was visiting from North Carolina and had never seen a professional baseball game. Needless to say, he did not see this one either. The game was postponed due to a 7.1 magnitude earthquake centered on the San Andreas Fault in the Santa Cruz Mountains near Loma Prieta Peak which is about 50 miles south of San Francisco. This quake only lasted between 10-15 seconds. To put it in perspective, the recent quake in Japan lasted for just over 2 minutes.
In college, geology was one of my favorite classes. I really enjoyed learning about the different ways in which the earth can change and move, as well as the reasons behind these changes. The world is truly an amazing place, and nature's effects, such as earthquakes, leave students with many questions. Why, for example, does the ground shake during an earthquake? Why does the earth shake more in places like Japan, and less often in places like Kansas? Why are there lots of smaller earthquakes, or aftershocks, after a large earthquake? Once students start asking questions such as these about earthquakes, the floodgates are likely to open, paving the way for additional questions about this mysterious and powerful event.
Here are some really fun activity driven resources focused on answering these questions and many more.
Musical Plates
Grade: 6-12

Earthquakes, a scientific and physical phenomenon, affect our lives in many ways. In this project, students use Real-Time earthquake and volcano data from the Internet to explore the relationship between earthquakes, plate tectonics, and volcanoes. This resource also has many links including links to seismicity maps for each state. This resource is from the Center for Improved Engineering & Science Education.
What’s Shaking?
http://www.thegateway.org/browse/dcrecord.2008-12-10.4019663742
Grade: 6
This lesson is a mini-unit on earthquakes. Students will watch videos, complete drawings and diagrams, and work in collaborative groups as they investigate such things as faults and the causes and effects of earthquakes. Students will also learn about seismic waves and how earthquakes are measured. There are also suggestions to extend the lesson as well. This resource is from the Alabama Learning Exchange.
Earthquakes
http://www.thegateway.org/browse/20486
Grade: 3-12
What are earthquakes? Why do they occur? and Why can't we predict them? Although we still can't predict when an earthquake will happen, we have learned much about earthquakes as well as the Earth itself from studying them. We have learned how to pinpoint the locations of earthquakes, how to accurately measure their sizes, and how to build flexible structures that can withstand the strong shaking produced by earthquakes and protect our loved ones. The homepage of this resource has some really fun links as an exhibit map. This is how you navigate through the resource. This resource is from the Tech Museum of Innovation.
Earthquakes: A Whole Lot of Quakin’ Goin’ On
http://www.thegateway.org/browse/dcrecord.2010-01-17.5080835734
Grade: 9-12
In this activity, students will delve into seismology, the study of earthquakes, learning about and contrasting two scales used by seismologists to categorize and compare these quaking forces of nature. Students will review firsthand accounts from people who experienced an earthquake, then employ one of these scales to categorize and map the earthquake's intensity. This resource is from National Geographic and includes related links and suggestions for extending the lesson.
These are just a few of the many resources available on The Gateway involving the study of earthquakes. Joann has chosen many more resources to feature throughout the week on Facebook and Twitter, so please join us there to learn more!

Japan – Earthquakes
Earthquakes are mysterious things. We understand why earthquakes happen, but still lack the ability to predict the magnitude of a quake or when such an event might occur. Once an earthquake begins, current technology can only provide a few seconds’ warning before severe shaking arrives at a specific location. For most people, the first sign of an impending earthquake occurs only once it’s begun.
Severe earthquakes have been mentioned throughout history, with the earliest recorded quake noted in China in 1177 BC. Scientific research into earthquakes didn’t really commence until the 18th century, where one commonly accepted theory held that earthquakes were caused by subterranean air surging out of vast caves beneath the Earth’s surface. It wasn’t until the twentieth century that the notion of plate tectonics began to develop, and for scientists to begin to understand what really caused an earthquake. Earthquakes are nearly always caused by the friction and stress associated with tectonic plate movements; as plates continuously strain and push against each other, a sudden release of energy caused by one plate slipping over another can result in an earthquake.
The 21st century thus far has spawned some massive earthquakes around the globe; as of this writing, Japan alone has seen 19 earthquakes of magnitude 7.0 and above in the last ten years. The island nation is located in the infamous Ring of Fire, a volatile region that rims the Pacific Ocean for roughly 25,000 miles and is notably home to 452 volcanoes and 90% of our planet’s earthquakes. Japan lies on the edge of the junction to three tectonic plates – the Philippine, Pacific, and Eurasian Plates – which continuously shift and grind over and under one another.
Like all disasters, the Japanese earthquake and tsunami have an effect on populations far from the stricken geographic region. Millions of people around the world are moved emotionally by the tragedy, and donate to Japanese relief efforts to signify their support and human solidarity. Traces of radiation were found on planes from Japan at O’Hare Airport in Chicago, docks and vessels were destroyed on the coasts of California and Hawaii due to waves caused by the tsunami, and the destruction from the earthquake and tsunami will have economic repercussions worldwide. And according to NASA, the March 11 earthquake was powerful enough to shift the Earth’s mass so that our planet spins a bit faster, thus reducing the length of each day by 1.6 microseconds. Thus the scope of one event – an earthquake – has created a ripple effect of significant proportions throughout the world.
My picks this week focus on understanding earthquakes and their impact on local and distant communities. Throughout the week, I’ll be featuring many additional lessons and activities on our Facebook and Twitter pages, so please check those pages for lots of ideas.
Table-Top Earthquakes
http://www.thegateway.org/browse/26190
Subjects: Geology, Earth science
Grade: K-12
Using an earthquake machine (materials list is included in the resource), the teacher can demonstrate how the machine’s sliding motion mimics the intermittent fault slippage that characterizes the earthquake fault zones. This demonstration of seismology for teachers and students can be used to expand lessons in earth science, physics, math, social studies, and geography. This activity was produced by the U.S. Geological Survey, a science organization that provides all types of information to scientists, policymakers, and others. Additionally, the USGS helps to help educate the public about natural resources, natural hazards, geospatial data, and other issues through lesson plans, maps, and data.
Building Structure Exercise: Designing Structures To Perform Well During an Earthquake
http://www.thegateway.org/browse/dcrecord.2011-03-23.5175455774
Subjects: Engineering, Geology, Physical science
Grade: 6-12
Did you ever notice that after an earthquake some structures have a lot of damage while others have little? There are different factors that affect how structures perform during an earthquake. In this activity, students will learn about the effect of different variables on building performance during a simulated earthquake. They’ll learn about what physical forces are at work during an earthquake, and brainstorm ways to strengthen the buildings to withstand an earthquake. This activity was produced by MCEER Information Systems, a national center dedicated to the creation and development of new technologies to equip
communities to become more disaster resilient in the face of earthquakes and other extreme events.
You Don’t Need a Seismograph to Study Earthquakes
http://www.thegateway.org/browse/32585
Subjects: Geology, Physical science
Grade: 7-12
Earthquakes are difficult to predict, and most of our scientific investigation occurs after the event. This lesson will help students to understand earthquakes. Students will simulate p waves (longitudinal) & s waves (transverse) using a slinky and rope. They will simulate one of the three types of lithospheric boundaries and investigate plate tectonics at some select web sites. This lesson is aligned to national education standards, and was produced by PBS NewsHour, which covers national and international news. NewsHour also provides educational resources for both teachers and students.
