Recently, a large amount of data, indicating induced seismicity in area of large underground nuclear tests (UNE), has been accumulated. Such studies were conducted on Amchitka Island (USA), Nevada Test Site (USA) and Semipalatinsk Test Site (USSR). Researchers considered three types of impacts: seismic activity associated with the destruction of the explosion cavity, induced tectonic activity...
The New Manual of Seismological Observatory Practice, NMSOP, is a compendium of seismological knowledge needed to run seismic networks and observatories. It is intended to facilitate the use and analysis of digital data acquired by seismic networks with a general focus on modern systems. Nevertheless, most of the Nuclear Explosions that occurred in history were recorded on analog...
Legacy seismograms contain unique data about past events, nuclear explosions among them, crucial to study and analyze past and present monitorization efforts. Unfortunately, many collections of these original data and their related accessory documentation are still in risk because of inadequate storage conditions and lack of proper recognition. At many institutions personnel and resources...
Historical geophysical data recorded during the peak of nuclear testing is rare and limited. Efforts have been made to preserve and digitize data but have minimal quality control from decades of lost history and retiring personnel. The Livermore Nevada Network (LNN) is a seismic network in California, Nevada and Utah deployed in the 1960s to record nuclear explosive testing at the Nevada Test...
In recent years, the seismological community has recognized the critical importance of preserving analogue seismic data. However, Germany was lacking strategies for preserving these records. Here we present the preliminary findings of our feasibility study, which evaluates the potential for digitizing all analogue seismic data in Germany.
Initial inventory of the contents of German analogue...
