The Technology Seismograph‐Station

Abstract

After long delays in securing the instrumental equipment, the Technology Seismological Station was put in operation July 5, 1932. This seismograph is on the grounds of the Surveying Camp operated by the Massachusetts Institute of Technology, and is just north of United States Route 1, on Gardner Lake, about six miles east of Machias, Washington County, Maine. The equipment consists of two horizontal components of the Wenner seismometer, mounted on a low concrete‐pier about four feet by six feet, resting on an outcropping ledge. The building is of concrete with enclosed airspace on the walls and ceiling, and also on the roof. The room is entered through two outer rooms. The walls are banked with earth up to the eaves. The rather serious moisture‐difficulties encountered at first now appear to have been overcome.
