The objective of NGA-East is to develop a new ground motion characterization (GMC) model for the Central and Eastern North-American (CENA) region. The GMC model consists in a set of new ground motion prediction equations (GMPEs) for median and standard deviation of ground motions (GMs) and their associated weights in the logic-trees for use in ...

As a combat support agency, NGA operates in dozens of locations around the world to support the U.S. military combatant commands and international partners, the U.S. intel community and “Five Eye” partners and allies.

NGA Campus East Address: 7500 GEOINT Drive, Springfield VA 22150. The most current directions are listed below. Of all the direction-finding websites, Google Maps has the most accurate, up-to-date information. All major road connections to the NCE are open. Some minor construction work is ongoing, but the roads are all open. All NCE gates are open.

NGA-East -- Central & Eastern North-America. The objective of NGA-East is to develop a new ground motion characterization (GMC) model for the Central and Eastern North-American (CENA) region.

All ground-motion tools compute the Weighted Average model for both the median and sigma. Both Ergodic and Single-Station sigmas can be computed. In addition the Excel tool computes the individual models (17 models for the median, two models for sigma). NOTE: All of the tools compute the values for the reference Vs30=3000 m/sec, and for 5% damping.

Apr 1, 2015 · The objective of NGA- East is to develop a new ground motion characterization (GMC) model for the Central and Eastern North America (CENA) region. The tectonic region of interest reaches across into Canada; thus, the term CENA instead of CEUS is used.

This report documents recent ground motion models (GMMs) developed as part of the Next Generation Attenuation for Central and Eastern North America (CENA) project (NGA-East).

The NGA-East database constitutes the largest database of processed recorded ground motions in Stable Continental Regions (SRCs). It was developed as part of a large multi-disciplinary research project coordinated by PEER.

Jul 13, 2021 · In this article, we present an overview of the research project NGA-East, Next Generation Attenuation for Central and Eastern North America (CENA), and summarize the key methodology and products. The project was tasked with developing a new ground motion characterization (GMC) model for CENA.
