Signatures that are anticipated to be observed of a nuclear explosion is adequately known to the scientific community via accumulated knowledge of previous events. On-Site Inspectors are fully equipped to pick site-specific observables through their thorough training. However, it would be rather peculiar to anticipate conventional observables in a clandestine nuclear explosion, as signatures would be concealed to a great extent. Pertaining the verification ease on events of the atmosphere and oceans, a clandestine test will be confined to the subsurface, which detection is a tedious affair. Considered the Treaty-accepted technologies, fixed and partially outdated, along with a degree of concealment that violator may apply, a conclusive OSI would be a great challenge on a clandestine event. OSI is partially denied for luxury of advancing technology, while a possible violator hardly obstructed for the same, keeping the OSI verification in par with would-be Inspected State Parties needs to be critically analyzed. Emphasizing the necessity of lifting technological barriers, synergy of Treaty-accepted technologies via a versatile set of Inspectors who are trained to think out-of-box manner, probably enable to unearth possible cause of an event which a request has been triggered. Where tools and technologies are inadequate, human intuition prevails.
The availability of space-borne high resolution full-motion video such as Urthcast or Google’s Terra Bella offer new data sources for imagery analysts. These sensors capture up to 90 seconds of video over an area of interest in high resolution video. The videos are analyzed in industry-standard imagery exploitation software using specialized tools specifically developed for video analysis. Video may complement or enhance existing treaty verification analysis by offering more information for visual interpretation as well as offering additional input data to create digital elevation models. Because video may be used to show activities and motion on the earth’s surface, it may offer enhanced reporting methods for analysts. CTBTO’s International Monitoring System may use these datasets to cross-reference observations and the On-Site Inspection Division may complement this with their existing use of remote sensing. This presentation will highlight some of the existing processing and interpretation techniques developed for satellite borne video. Preliminary results show that elevation models from SkySat video imagery can recover height information of industrial buildings with a similar quality as satellite-borne sub-meter very high resolution optical stereo pairs.
Numerical modelling of seismic wave propagation and seismic motion in realistic models of local small-scale near-surface structures requires realistic physical models and sufficiently accurate numerical-modelling method. Realistic models may include non-planar material interfaces, smooth heterogeneities inside layers/blocks and frequency-dependent attenuation. We present an optimized FD scheme with a. reduced grid dispersion in sediments, b. more accurate discrete representation of an interface, c. more accurate representation of realistic attenuation. The reduced grid dispersion in sediments is due to an optimized FD approximation of spatial derivatives. The approximation combines the Taylor-expansion and dispersion-relation-preserving approaches. The resulting scheme differs from the standard (2,4) staggered-grid scheme only by values of two approximation coefficients. A new discrete representation of heterogeneous viscoelastic medium with material discontinuities is based on the assumption that an interface of two viscoelastic media with the generalized Maxwell body (GMB-EK) rheologies can be approximated by an averaged orthorhombic medium with the GMB-EK rheology and the optimal procedure for a joint determination of the anelastic coefficients and distribution of the relaxation frequencies for an arbitrary Q(omega) law. The improved numerical modelling will be applied to the set of structural models of an underground cavity after a nuclear test explosion in the vertical emplacement.
A demonstration experiment was recently conducted in the state of Oklahoma in the USA to evaluate strategies for observing the full seismic wavefield, for events at local to teleseismic distances and across a wide range of frequencies. The experiment tested new instrumentation and deployment strategies, producing an open-use dataset for evaluating a range of array processing techniques. The field effort, organized by the Incorporated Research Institutions for Seismology, used a crew of ~50 students and faculty to deploy 363 3-component "nodal" sensors along three seismic lines and in a seven-layer nested gradiometer array. The seismic lines spanned a region ~13x5 km. A broadband, 18 element "Golay 3x6" array was deployed with an aperture of approximately 5 km, encompassing the two nodal arrays. In addition, 9 infrasound stations were deployed to capture and identify acoustic events that might be recorded by the seismic array. We summarize the design considerations for the gradiometer and Golay arrays, along with preliminary analyses of the data. We examine the performance of the various types of instrumentation, including co-located surface and buried nodes, and co-located nodes and broadband stations. We present ground motion visualizations illustrating the wavefield complexity observed by these arrays.

The ASHE Asia project is an international collaboration between National Data Centers, operational agencies, and research organizations to improve early notification of potentially hazardous eruptions in Asia and the Western Pacific. The increased availability of open seismo-acoustic data in the ASEAN region and recent advances in mobile distributed sensors networks can reduce notification latency of hazardous volcanic eruptions. We use the IMS network in combination with established technologies and next-generation smartphone sensing systems to detect and characterize eruptions in the Asia-Pacific region that can inject volcanic ash at aircraft cruising altitudes. The Volcano Explosivity Index (VEI) is an operational metric traditionally used in the monitoring community, where a VEI 4 eruption injects ash above 10 km. The initial ASHE Asia V4R4 technical objective is to automatically detect and report eruptions with a VEI 4 and above within a maximum notification latency of 4 hours (~4,000 km range). We will implement standardized metrics to provide actionable reports with the eruption location, time, duration and VEI-equivalent energy. These reports would provide relevant eruption characteristics that can be used to trigger ash dispersion models by Volcanic Ash Advisory Centres or individual meteorological services for ash and aviation safety.
Seismic threat and related earthquake engineering dedications usually require evaluation of return periods or probabilities of exceedance of specific levels of design load criteria or extremal safety conditions. For the purpose, a comprehensive treatment of earthquake hazard estimation, Gumbel’s type-I extremes event probability distribution have been used to estimate designed earthquake recurrence times using annual extreme magnitudes. Hindukush–Pamir Himalaya and their vicinity bounded by 25–40°N and 65–85°E have been selected for quantify future earthquake hazard and risk. The result of analyses have enabled earthquake hazard that exist in the Hindukush-Pamir Himalayan belt to be quantified in terms of recurrence periods and probabilities of occurrence of earthquake of any given magnitude. Seventeen years complete and reliable earthquake data from June 13, 1999 to March 12, 2015 have been taken from International Monitoring System (IMS) Network setup by Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), Vienna Austria. Study indicates that the most probable largest annual earthquakes are close to 5.5. The most probable earthquakes that may occur in an interval of 50 years are estimated as 6.6. The results are potentially useful for probabilistic seismic hazard assessment in the region.
Anthropogenic events of interest to the nuclear treaty monitoring community are typically observed seismically and in some instances acoustically. The number of these events seem to be ever increasing as additional sensors continue to be installed and existing stations are tuned to improve detection capability. The use of non-traditional data sources, such as social media, can corroborate geophysical detection network data. For example, the U.S. Geological Survey’s use of Twitter to track earthquakes in populated areas as an alternative data source can aid in situational awareness of ground shaking intensity. The USGS can use social media such as Twitter to alert them before the earthquake is detected by their sensors. These types of alerts help aid the timeliness of first responders to the scene. We incorporate social media into the analysis of events to better characterize sources observed in waveform data sets. This could potentially assist in identifying previously unknown sources and may enhance the scientific community’s ground truth data collections.
The nuclear tests by the Democratic People's Republic of Korea (DPRK) have generated both seismic and infrasonic signals. This presentation will address seismo-acoustic analyses of these tests. Special focus will be given to the 2013 and January 2016 tests, that were estimated to have a similar yield. Clear detections were made in the Russian Federation (I45RU) and Japan (I30JP) in 2013 at stations from the International Monitoring System. Both tropospheric and stratospheric refractions arrived at the stations. In 2016, only a weak return was potentially observed at I45RU. Data analysis and propagation modeling show that the noise level at the stations and the stratospheric circumpolar vortex were different in 2016 compared to 2013. A relative analysis of the 2013 and 2016 DPRK tests, in combination with atmospheric infrasound propagation modeling, motivates the hypothesis that the 2016 test was at a greater depth than the 2013 test. In such a case, less seismic energy would couple through the lithosphere-atmosphere interface, leading to less observable infrasound. A preliminary analysis suggests that the 2016 test occurred at least 1.5 times deeper. Since explosion depth is difficult to estimate from seismic data alone, this motivates a synergy between seismics and infrasonics.

T2.1-P18 The Seismic Event in North Korea 9 September 2016
Amplitude ratios between the first 2016 and 2013 North Korean nuclear tests for different kinds of seismic waves are compared. The observations show the first 2016 test had generated stronger Rayleigh waves with weaker short period P and Love waves in comparison with the 2013 test. Based on the observations, secondary seismic sources including the DC components caused by tectonic releases and the CLVD components caused by induced rock damages of the explosions are determined. It is shown the DC sources of the two tests should have an identical thrust faulting mechanism with DC moment MDC of the first 2016 test smaller than that of the 2013 test, and the ratio between the CLVD moment MCLVD and the isotropic moment Miso is between 17~27% for the 2013 test, 0.7~11% for the first 2016 test, both much lower than that for underground nuclear explosions detonated by standard yield-scaled burial depth and of similar mb. The above mentioned results suggest the tectonic releases have significant effect on Ms for DPRK nuclear tests, which is of important implications for understanding the mb:Ms criteria and Ms-yield scaling.
We analyze seismic and infrasound signals generated by five underground nuclear tests in North Korea in 2006, 2009, 2013, and 2016 (January and September). Regional data from six seismo-acoustic arrays, cooperatively operated by Southern Methodist University (SMU) and Korea Institute of Geosciences and Mineral Resources (KIGAM) in the Korean peninsula, were used with two additional infrasound arrays operated by KIGAM and an additional seismic station in China. We explore the relative seismic source scaling of Pn, Pg, Sn, and Lg phases, using the Mueller and Murphy (1971) and Denny and Johnson (1991) source models. This analysis constrains a range of relative source strengths and depths. We analyzed infrasound signals detected from all the explosions using an automatic detector and compared these with the model predictions using time dependent atmospheric specifications. These results suggest that infrasound detections from the five explosions are strongly dependent on atmospheric condition at the time of each explosion (best detectability in January 2016 case) with infrasound event locations improved using this information. Future work is needed to integrate both seismic and infrasound analyses to provide combined constraints on source depth as well as free surface interactions near the source.
The CTBT and the Ban Treaty Edward Ifft The UNGA recently voted to authorize negotiation of a treaty banning nuclear weapons. This negotiation will end July 7, shortly after the conclusion of SnT 2017. It may appear that there would be little relationship between such a treaty and the CTBT, but there may be important technical, legal and political issues between the two. The Ban Treaty (BT) will ban the testing of nuclear weapons, so we may have in force a legally binding document that explicitly prohibits the testing of nuclear devices well before EIF of the CTBT. Efforts for and against the BT may distract from the CTBT. A strong case can be made that efforts to universalize and bring into force the CTBT should have priority. Also will the BT only refer to "testing," or will it explicitly specify "explosions?" Will operative terms be defined and obligations with respect to what is/is not allowed be exactly the same as in the CTBT? If not, the possibility of ambiguities and contradictions is clear. Will the BT attempt to define a "nuclear explosion," something that was purposely not done in the CTBT? All these issues bear careful watching.

Discussion and Arrangements
Globalized Data Dissemination in near real time is a challenge. Data replication as an alternative is cost intensive and delayed. Therefore, one of the possible solutions is to develop a protocol that classifies data at source. This sorting of data is based on spatial, temporal and spectral significances defined at the source. Parametric thresholds, i.e. boundary conditions for classification, are part of the architecture resulting in propagation ready warehousing of data at source. Optimizations are also achieved by propagating only variations to the standard data or most specific conditions. This results in a sizable reduction of data transmitted over the networks. The complete data set or subset, as may be applicable, can be rebuilt at the remote site by adding variations to the standard conditions generating data as recorded by the sensors. This protocol can be implemented at the transport or higher layers of the Open Systems Interconnection model. New fields are required in the existing database designs to accommodate only keeping records of received variations. A furtherance to this optimization can be achieved by only recording variations at sensors even prior to the analogue to digital conversions and transmission can also be investigated with possibly fascinating outcomes.

From definitions of weapons, to articles governing verification of compliance, inspection, and assistance, science and technology underpin international disarmament treaties. Both treaty negotiation and implementation require sound technical advice to inform policy; requiring scientific advisers. Despite this need for science in disarmament, the two worlds are often at odds. The Chemical and Biological Weapons Conventions serve to illustrate this tension, where to some, scientific developments raise concerns about misuse potential and security risk, while others see opportunities for innovation in treaty implementation and solutions to pressing global issues. Science is only one of many dimensions that policymakers must consider in decision making, yet the worldâs current security environment shows a need for scientifically literate policymakers and scientist-policymaker engagement that has never been greater Actionable science advice for policy requires experts capable of clearly communicating with those receiving advice. In this regard, the Chemical Weapons Convention (CWC) serves as a case study on involvement of scientists in treaty negotiation, compliance verification, providing advice to policymakers, and as science communicators to policymakers. We will discuss experiences and lessons learned from the CWCâs science advisory mechanism; lessons informative for nurturing the science-policymaker engagement required to meet current and future disarmament challenges.
Global Verification extends far beyond the standard tools of International Monitoring System (IMS), and act as the common platform for public interaction; a platform to share knowledge. The tools of Global Verification regime would be a library of knowledge varying from physical earth characters to possible physiological behaviour of a would-be Inspected State Party. Whereas, On-Site Verification is a specialized and robust operation, confined to specific expertise, due to strict code-of-conduct and sensitivity of the outcome. The two entities, marry effectively forming a continuous process towards successful verification via IMS products. On a specific event, IMS products along with Global Verification tools produces an effective framework for OSI initiation. The whole process is a continuous flow zooming into the area of interest, adding layers as progress, towards fruitful On-Site Verification. Considered the developing trends of remote sensing techniques, the challenges on evolving a full-fledged remote Global Verification mechanism hardly a technical aspect, yet political, as constrains will be imposed on usage of the technology under the pretext of "national security". However, identifying the Global Verification norms in its practical domain and appropriate linkage with the On-Site inspection tools and functionality, enables to overcome many the challenges that Verification demands.
