Case of the Shaky Quake, Part 2 | NASA SciFiles
In The Case of the Shaky Quake, the tree house detectives feel a strange tremor and begin to think that an earthquake has occurred. The detectives set out to investigate plate tectonics and earthquakes. As they begin the investigative process, the detectives get a little help from Michael Lyle, a seismologist at Tidewater Community College in Virginia Beach, Virginia, Heidi Stenner of the United States Geological Society (USGS) and David Whitman at the National Dinosaur Monument in Utah. The detectives also visit Dr. Carol Tang at the California Academy of Sciences to "experience" an earthquake. Mr. Ron Baalke and Dr. Andrea Donnellan at NASA's Jet Propulsion Laboratory (JPL) help the detectives come to an amazing discovery as they realize that plate movement is not the only thing that makes the Earth tremble.
