TASK-DI-09-01B: Seismographic Networks Improvement and Coordination

Task Description

Task Definition

Improve the capabilities of global seismographic networks such as GSN, FDSN (including regional and global components), GNSS networks and new ocean bottom networks such as VENUS, NEPTUNE and ESONET. Facilitate sharing of data and event products among GEO members. Expand and coordinate efforts to provide access, using GEOSS interoperability methods, to real time and archived seismological data and products. Develop a portal that will interlink distributed seismological data centers and provide seamless access to other GEOSS components. Broaden the scope of this activity to identify and build upon synergies across in-situ observing network types (e.g. seismological, GNSS, hydrological). Synergies could range from the use of the same best practices and operational approach, to the use of a common part of the infrastructure for collection and dissemination, and co-location of in-situ instruments.

Architecture and Data

1) Please briefly describe any task-related Earth observation resources (data set, system, website/portal) and any related Web Service interfaces that are contributed to GEOSS. State whether these items are or will be registered with the GEOSS Component and Service Registry for access via the GEO Web Portals, and whether any associated standards or other interoperability arrangements will be registered in the Standards and Interoperability Registry.

2) Please also describe what data and information your activity/system needs that you would request to be accessible through the GEOSS Common Infrastructure.

Capacity Building

(capacity building is defined to include the development of capacity related to: (i) Infrastructure and technology transfer (Hardware, Software and other technology required to develop, access and use EO); (ii) Individuals (education and training of individuals to be aware of, access, use and develop EO) and (iii) Institutions – building policies, programs & organizational structures to enhance the value of EO data and products).

1) In accordance with the above definition does this Task have a capacity-building component? If so, please provide a short description of this component including a description of end users.

2) Have any additional CB needs for this Task been identified? Please provide a short description.

Science and Technology

1. Please briefly describe the elements of scientific research or technological development contained in this Task

2. In relation to the S&T component(s) of this Task, please describe gaps, priorities, continuity needs, barriers, scientific expertise and additional resource needs (this information will be used for developing a gaps and needs assessment in Task ST-09-01)

User Engagement

Please briefly describe to what extent end users are engaged in this Task and influence the nature of the outputs produced

Disaster Management agencies sit on the steering committees for several of the sub-tasks. They are involved in the defition of the workplan, particualrly in defining the deliverables that will be used by them for improved disaster management. Users will led the evaluation process after each phase to ensure that the results are judged as a function of their relevance to user goals and objectives.

Contribution to Outputs and Activities Above

China

Seismographic Network Division, China Earthquake Networks Center (CENC): China Earthquake Networks Center (CENC) undertakes the following tasks: real-time collecting, processing and storing the data of 31 regional seismic networks data in China; rapidly reporting strong earthquake's parameters; producing monthly seismological catalogues; compiling and publishing "Observation Report of Nation Digital Seismic Network" and "Observation Report of China Seismic Stations"; Storing and maintaining nationwide various seismic data, periodically collecting and storing the observation data recorded by mobile seismic stations; operating and maintaining World Data Center for Seismology, Beijing. CENC will improve the capability of seismographic networks in Asia, and share its continuous data and event data. By the web site of World Data Center for Seismology, Beijing, CENC will facilitate GEO members to access the data in CENC.

Germany

DLR DFD-KA: Set-up of the Network for Detection of Mesopause Change, NDMC in order to also detect infrasound from seismic events.

Japan

JAMSTEC: contributes to the upgrading in the function of the global earthquake observation network by improving land and marine earthquake observation network of West Pacific Ocean region operated by JAMSTEC.

NIED: contribute to strengthening global earthquake observation networks by installation and operation of broadband seismometers in Indonesia and other countries and collecting online data.

USA

The Incorporated Research Institutions for Seismology (IRIS) Consortium and the U.S. Geological Survey (USGS) jointly operate the Global Seismographic Network (GSN)—a permanent network of state-of-the-art seismological and geophysical sensors connected by available telecommunications. All data are openly available in real-time without restriction. The GSN provides data for earthquake response, tsunami warning, international nuclear treaty monitoring, and serves as a foremost resource for seismological research and for training and educating the next generation of earth scientists.

The USGS and IRIS, through collaboration and cooperation with national and international partners, are working to increase the capability and capacity of global earthquake and tsunami monitoring networks. This is being achieved by expanding the GSN and affiliated networks, by upgrading their telemetry, through the development of software to enhance product quality and delivery, and through participation in workshops and training programs with regional partners. The USGS obtains rapid estimates of seismic event parameters within 12-15 minutes of an earthquake’s origin that are expeditiously disseminated worldwide. Work continues to improve post-earthquake information products, including a rapid estimate of the impact of an earthquake on the local population. PAGER (Prompt Assessment of Global Earthquakes for Response) and ShakeMap are publicly available products that provide rapid estimates of societal impact from major earthquakes worldwide, based on estimates of people and property exposed to potentially damaging levels of ground motion. The IRIS Consortium operates a Data Management System, archiving data from over 5,000 seismic stations—of which over 1,000 are available in near-real-time—and a wide range of other geophysical sensor channels. All data are freely and openly available from www.iris.edu.
