Hi, I guess this article is all over the news and mentions the federal government; so it may come up in your libraries, too : The Really Big One: An earthquake will destroy a sizable portion of the coastal Northwest. The question is when. http://www.newyorker.com/magazine/2015/07/20/the-really-big-one Here are the information sources available online from the U.S. Geological Survey (USGS) that I disseminate for earthquake inquiries; mostly to show the public what we do and how the government monitors these hazards : ~~~~~~~ To view the earthquake network stations on Earth : http://earthquake.usgs.gov/monitoring/operations/ ANSS: http://earthquake.usgs.gov/monitoring/anss/ Global: http://earthquake.usgs.gov/monitoring/operations/network.php?network=GSN National Strong Motion Project : http://earthquake.usgs.gov/monitoring/nsmp/ ~~~~~~~ Earthquake hazard maps : http://earthquake.usgs.gov/hazards/?source=sitenav includes: custom hazards maps: http://geohazards.usgs.gov/hazards/apps/cmaps/ and custom earthquake probability maps for your neighborhood : http://geohazards.usgs.gov/eqprob/2009/index.php ~~~~~~~ Largest Earthquakes in the United States: http://earthquake.usgs.gov/earthquakes/states/10_largest_us.php The second largest earthquake = the Cascadia Subduction Zone (Pacific Northwest) : USGS: http://earthquake.usgs.gov/earthquakes/states/events/1700_01_26.php Natural Resources, Canada: http://www.earthquakescanada.nrcan.gc.ca/histor/15-19th-eme/1700/1700-eng.php Please note the other large earthquakes in Missouri and South Carolina...

Also, if your agency wants a tour of the USGS National Earthquake Information Center (NEIC), here is the contact information : http://earthquake.usgs.gov/contactus/golden/neic.php I hope that helps and(or) saves you time searching for our USGS products!
