Seismograph Exhibit
The new Seismograph Exhibit for the Arkansas Museum Network is finished! Many thanks to J. Lahr (USGS), Dave F., Andrew L., Klover K., and Pearl T.(Exploratorium).
A seismograph measures the magnitude of an earthquake by sensing and recording the shaking it causes. Extremely sensitive seismographs can detect earthquakes too small to feel, even those happening on the far side of the globe.

Detail: The lever allows visitors to touch the sensitive beam of the seismograph and see the resulting wave motion.
