Resolution of the Eleventh Joint Meeting of the U.S.-Japan Panel on Earthquake
Research (UJNR)
November, 2016
The UJNR Panel on Earthquake Research promotes advanced research
toward a more fundamental understanding of the earthquake process and hazard
estimation. The Eleventh Joint meeting was extremely beneficial in furthering
cooperation and deepening understanding of problems common to both Japan andthe U.S.
The meeting included very productive exchanges of information onapproaches to systematic observation and modeling of earthquake processes.
Regarding the Earthquake and tsunami of March 2011 off the Pacific coast of
Tohoku and the 2016 Kumamoto earthquake sequence, the Panel recognizes thatfurther efforts are necessary to achieve our common goal of reducing earthquake
risk through close collaboration and focused discussions at the 12th UJNR meeting.
We look forward to continued cooperation on issues involving the densification ofobservation networks and the open exchange of data among scientific communities.
We recognize the importance of making information publicly available in a timely
manner. We also recognize the importance of information exchange on researchpolicy and strategies, including the frameworks of research organizations.
Areas of Cooperation
Specific areas of earthquake research where cooperative research between
Japan and the U.S. may lead to significant advancement include, but are not limited
to:-Probabilistic earthquake and tsunami hazard estimation, including
extraordinarily large earthquakes, both in our respective countries andworldwide, incorporating knowledge of current and past behavior, andphysics based computational models;-

Real-time information from seismic, geodetic and strain measurements,
including borehole strainmeters and seafloor observations using offshore
cabled networks;-Technologies for measuring crustal deformation including GNSS, GPSacoustic, InSAR, LiDAR, VLBI and SLR;-

Early warning technologies for earthquakes and tsunamis;-

Studies of recurrence of large and extraordinary large earthquakes using
paleoseismic, paleotsunami, geodetic and seismic methods;

-Studies of earthquake sources and fault-zone processes using observational,experimental, theoretical, and in situ methods;-

Studies of episodic tremor and slow slip events using seismic, geodetic,
borehole strain measurements, and simulation techniques;-

Systematic studies of earthquake predictability through rigorously evaluatedscientific prediction experiments and robust databases;-Studies of strong ground motions, geological effects and the response ofengineered structures;-Observations and research on the causes and effects of earthquakes inducedby fluid injection.

The Panel strongly urges that the appropriate agencies in Japan and the U.S.
that are represented on this panel work together with the academic sector tosupport and coordinate scientific work in these areas of cooperation.
The Panel recognizes the importance of promoting the exchange of scientificpersonnel, exchange of data, and fundamental studies to advance progress inearthquake research. Japan and the U.S. should promote these exchanges
throughout the world. The Panel endorses continuation of these activities.
Next Meeting
The next meeting will be held in Japan in the autumn of 2018.
