Monitoring Earthquakes across the United States
"Those who plan for and respond to earthquake disasters, and those who study earthquakes, require timely notification of earthquake occurrences and information to mitigate losses. Earthquake events throughout the United States are currently monitored by sophisticated systems that provide the notification and information needed by decision makers before and during times of crisis. The national and regional earthquake monitoring systems for the United States have evolved into one of the world's finest emergency-management and research tools."

National Earthquake Information Center Strategic Plan, 2019-23
From the Executive Summary: "Damaging earthquakes occur regularly around the world; since the turn of the 20th century, hundreds of earthquakes have caused significant loss of life and (or) millions of dollars or more in economic losses. While most of these did not directly affect the United States and its Territories, by studying worldwide seismicity we can better understand how to mitigate the effects of earthquakes when they do occur within U.S. borders. Within the U.S. Government, this mandate falls on the U.S. Geological Survey (USGS) National Earthquake Information Center (NEIC), which has the statutory responsibility for monitoring and reporting on earthquakes domestically and globally. [...] To maintain its prominent position in earthquake monitoring, the NEIC must continue to evolve, concurrently improving its operations and 24/7 robustness, streamlining services and infrastructure, and keeping pace with research and innovation in the field of seismology. This document outlines how the NEIC might best achieve such goals, by describing specific avenues and opportunities for development in the next five years (2019-23)."

Seismicity of the Earth 1900-2018
From the Document: "This map illustrates 119 years of global seismicity in the context of global plate tectonics and the Earth's physiography. Primarily designed for use by earth scientists, engineers and educators, this map provides a comprehensive overview of strong (moment magnitude [M] 5.5 and larger) earthquakes since 1900. The map clearly identifies the locations of the 'great' earthquakes (M 8.0 and larger) and the aftershock or rupture area (in green fill), if known, of the M 8.3 or larger earthquakes. The circular earthquake symbols are scaled to be proportional to the moment magnitude and therefore to the area of faulting, thus providing a better understanding of the relative sizes and distribution of earthquakes in the magnitude range 5.5 to 9.5. Plotting the known rupture or aftershock areas (which are closely related) of the largest earthquakes also provides a better appreciation of the faulting extent of some of the most famous and damaging instrumentally recorded earthquakes in modern history."
