Our Seismograph

Through generous funding from individuals, groups and businesses, the Merrimack Public Library became the first public library in New Hampshire to house a working seismograph and join an international network of seismic monitoring centers in June 2014. The EQ-1 seismograph is installed in the Lowell Room.  Please contact Library Director Yvette Couser via email

if you would like to plan a class visit to learn more about the machine.

A seismograph in a library? Why?

Hosting a working siesmograph in our library is an exciting and unique way for the library to fulfill its mission to enhance life-long learning in our community.  By partnering with the Boston College Educational Seismology Project (BC-ESP) we have geophysicists, seismologists, and geologists from the Boston College Department of Earth & Environmental Sciences training library staff, patrons, home-school groups, seniors, teachers, school classes - all citizens who wish to become "citizen scientists" - how to read and analyze data collected from seismic events (earthquakes) around the world.


On October 16, 2012,  a 4.6 quake that shook Hollis, Maine was felt throughout the region.  It also happened to occur during a Merrimack Library Trustees' monthly Business meeting and recorded by Merrimack TV
