In every InSights issue, ESNO features two of the dozens of tools, modules, and activities that utilize EarthScope data to benefit a wide variety of users (K–12, university educators, informal programs like museums or after-school programs).
Looking up from below and northward along the San Andreas fault zone in the vicinity of the SAFOD core. The drill site, marked by a star, is projected on the green and tan ground surface. Multiple strands of the San Andreas fault are mapped with black lines. The red path of the main SAFOD line intersects the fault at depth, where numerous earthquakes (shown as white balls) happen continuously. (Image from L. Blair, U.S. Geological Survey)

A Writing Intern in the Field


As the science writing intern for the EarthScope National Office, field work is not generally a part of my job.
Access to SALMON station SALA in western Cook Inlet, showing challenging conditions. At high tide, all the rocks in view are underwater. Here a three-wheeler pulling a trailer is being driven onto the boat at a falling tide. Note the typical bluffs in the background; these bluffs posed challenging access to sites on top.(Credit C.Tape)
