Seismic instruments at the Rolnick Observatory
The New England Seismic Network (NESN), located in Weston Massachusetts, installed a seismic vault July 15th, 2011 at the Rolnick Observatory that hosts 2 instruments. One is a seismometer that measures global earthquakes and the other is an accelerometer that measures big, local ones. While not strictly related to astronomy, we support all scientific research and love to share it with the public.
Visit the live view of the Rolnick Seismometer and take a look at recent seismic activity–the instruments are sensitive enough to detect most earthquakes all over the world!
The NESN page has historical drums that recorded the devastating 2011 9.0 earthquake in Honshu Japan as well as the 2010 7.0 Haiti quake and more. Big earthquakes like the August 23rd 2011 event are rare in New England but small ones happen often as they explain.
