|What is an Earthquake?: Revealing A Fault Plane with Hypocenters|
In this activity, students plot earthquake hypocenters along a cross-section in an attempt to create an image of a fault deep beneath the surface. The hypocenters they will be using come from the aftershock sequence of the magnitude 5.6 North Palm Springs earthquake that occurred in 1986. The students will learn that accurate positioning of earthquake hypocenters can produce a rough image of a fault, allowing subsurface determination of dip. They will also understand that obtaining this much data for a single fault usually requires a large aftershock sequence. A materials list and procedures are included: links are also provided to printable versions of the required map of hypocenters and the graphing template.
