If there ever were a teachable moment when it comes to tsunamis, physics, and fault lines, that moment happened in December. And Cornell graduate student Evan Variano made sure it was not lost.

Evan Variano, a graduate student in civil and environmental engineering, demonstrates a portable tsunami teaching device he helped build to an earth science class at Dryden High School Jan. 13.

In the wake of the devastating Asian tsunami, he took a lesson plan he developed—and a portable teaching device—to high schools in the Ithaca and Rochester areas during January to answer students’ questions about the physics of tsunamis, the technology required to detect the killer waves, and the economics and sociology of developing early warning systems.

“I’m trying to cover whatever the students are curious about,” said Variano, a graduate student in Cornell’s School of Civil and Environmental Engineering. His mentor is tsunami expert Philip Liu, professor of civil and environmental engineering, who led a fact-gathering delegation of American scientists from the National Science Foundation’s Tsunami Research Group and the U.S. Geological Survey into wave-ravaged Sri Lanka.

Variano, whose specialty is turbulence, is a fellow in the Cornell Scientific Inquiry Partnerships (CSIP) program. The fellowship is a National Science Foundation-supported program that gives 10 Cornell graduate students free tuition and a stipend in exchange for about 15 hours a week teaching in area public schools.

He is teaching high school students studying earth science, environmental science, and biology how underwater earthquakes trigger the destructive waves. The teaching device, which Variano built with the help of Cornell technicians Paul Charles and Tim Brock, is a tube that allows students to experiment to see how a tsunami develops differently depending on what type of shoreline it hits.

“The wave drives through the deep ocean at 500 miles per hour, and without losing energy it builds up to 30 feet tall as it approaches shallower water and the shore,” explained Variano. “When it hits the coastline, it’s the turbulence—the mixing—that hits from all sides and holds people underneath the water. This causes most of the death and destruction.”

Variano also makes a point of discussing more than the science of waves and earthquakes with the high school students, because, he said, “Science doesn’t happen in a vacuum.” Observed Karen Taylor, an earth science teacher at Dryden High School, where Variano visited in January: “Many eyebrows were raised when Evan shared with them the cost of an early tsunami detection system in the Indian Ocean [about $20 million] versus the amount of relief money donated worldwide [$3 billion to $4 billion] versus the amount of money the United States has spent on the war in Iraq [more than $20 billion]. Evan did a great job of clearing up some misconceptions the students had, and they learned quite a bit about wave formation and why the tsunami behaved as it did.”

Variano visited a half dozen schools by the end of January, to discuss both the science of tsunamis and the socioeconomic problems resulting from the disaster.
