The problem is that earthquakes start out many miles beneath the surface, too deep for us to observe them directly. So we study them from afar by (1) observing the geological changes at the ground surface, (2) analyzing the symphony of earthquake vibrations recorded on seismographs, and (3) monitoring the tectonic changes in .

The Northern Pacific built its main line from Kalama on the Columbia River to Tacoma on Puget Sound, closely following the Cowlitz Trail route through the South Sound country. The Lewis County Historical Museum, and the Tenino Depot Museum are both housed in classic depots dating from the heyday of the Northern Pacific Railroad. With the modern three-component networks in the Northwest and adjacent parts of Canada, it is possible to determine the push or pull relationship at many stations, leading to information about whether the earthquake is on a reverse fault, a normal fault, or a strike-slip fault (Figure ). earthquake-related lore from the Puget Sound area.
