Visit to Nicaragua -as a JICA Short Term ExpertBy Dr. Toshiaki Yokoi, Director of IISEE

I have traveled to Managua,Nicaragua from 19 to 28, April asa JICA short term expert andhave
instructedthefieldmeasurement
anddataprocessing of the microtremor
array exploration (mainly SPACmethod) in suburban area at thesouth of the Augusto Cesar
Sandino international Airport ofManagua.

GlobalSeismologicalObservation Course) who is working
for the Nicaraguan Institute of
Territorial Studies (INETER).

Managua
wasjolted
byanearthquake of M6.2 in April 10 andthe mass media was so interested inearthquakes that they interviewed
me. My images have appeared in a
newspaper and a few TV programs inNicaragua. I hope that it canstimulate the people's attention toMr. Castrillo (right)
the earthquake hazard, risk and themeasures. This is my third visit to Managua and I could enjoy my stay

Call for Papers
IISEE Bulletin is now
accepting submissionsof papers for the seismol og y, ea rt h qu ake
engineering, andtsunami. Developing
countries are targeted,but are n ot limited.

During our visit to Kansai District, we were able to visit cities like Osaka, Kobe
and Kyoto. The purpose of this study trip was to experience the current status
and recovery process of the areas that were affected by the Great HanshinAwaji Earthquake.
We visited centers like the Disaster Reduction andHuman Renovation Institution, which is very important
to transfer experience to the next generations, and EDefense, used as a vehicle to understand the behaviorof structures during an earthquake, enrich the design
methods and to study the effective methods ofretrofitting.
Akashi Kaikyo Bridge is a marvel of engineering.
Building the longest span suspension bridge of the world is, for sure, a very
complicated task, but with a good design, good considerations and research,
this kind of structures can exist.
In Kyoto we learned that efforts to preserve historical structures are very
valuable. The retrofitting techniques and all the meticulous procedures to do an
extraordinary repair work is a lesson for all of us to care more of our history.

(2)Ms. Erica Nora Flores Terreros (Peru, Earthquake Engineering Course)
In the middle of April, Seismology, Earthquake Engineering and Tsunami
courses had the last Study Trip in Kansai Region (Osaka, Hyogo and Kyotoprefectures).

Your original papers
will be reviewed by theeditorial members andsome experts.

The main objective of the study trip is to know and acquire the lessons learned
from the Great Hanshin-Awaji Earthquake (Kobe Earthquake, 1995), and also
gain knowledge about new technology and methodology for construction andretrofitting in temples like Nijo Castle and Kiyomizu-Dera Temple.

NO submission fee isneed.

After Kobe Earthquake, Japan’s important target is toimprove their Seismic Standard by studying the real
behavior of their building. In the trip, we had theopportunity to visit the world’s largest 3D shaking
table, and we could appreciate some building tested infull scale. Another place to get more my attention wasAkashi Kaikyo Bridge, the longest suspension bridge
engineering in the world, we could see some advanced
forconstructing
andtechnology,methodology
adjustment done in the design of the bridge, since it was still underconstruction when Kobe earthquake happened.

Try to challenge!!

Japanese government educates its population, building museums like great
Hanshin Awaji Memorial Museum to observe past seismic experiences about thedisaster and how to protect yourself from them through games anddemonstrations leaving great teachings for future generations. Once again I canconclude that Japan is one of the countries well prepared in natural disaster as
the Earthquakes.
The knowledge acquired in all our study trips was useful to understand theexperiences of past earthquakes, which is considerable information that we canapply to our countries’ developing and implementing policies of disastermitigation.

My Research Field
By Dr. Takumi Hayashida, IISEE Research Seismologist
It has been almost one year since I was assigned as a staff member of IISEE. I
am currently engaged in research on strong motion seismology that estimatessubsurface seismic velocity structures for the accurate prediction of long-period
ground motions.

In recent years, the seismic interferometry techniques(e.g., Shapiro and Campillo, 2004) are widely appliedin fields of exploration geophysics and seismology. It
can be used to extract inter-station Green’s functions(i.e. surface point excitation solutions that haveinformation about physical properties of sedimentarystructures) and evaluate propagation properties ofsurface waves (seismic waves that propagate along theEarth’s surface), by calculating the cross-correlation of
the diffuse wavefields.
I apply this method to microtremor data observed in sedimentary basins toobtain Green’s functions between arbitrary seismic station pairs and checkconstraint conditions for the improvement of existing seismic structure models.
I am also trying to combine this technique and other existing microtremor
survey methods [e.g., spatial autocorrelation method, Aki (1957); Okada(2003)] for further understanding of subsurface structures.
The microtremor survey will provide interesting information in seismology alongwith important information in the field of seismic engineering. I am going tovisit Managua, Nicaragua from this week to take part in the microtremor survey
project, following the Dr. Yokoi’s visit.

In Memoriam: Prof. Koji Fujima (Japan)
It was with profound sorrow that we received the sad news of the passing awayof Prof. Koji Fujima, Professor of Department of Civil and Environmental
Engineering, School of Systems Engineering, National Defense Academy ofJapan on May 2, 2014.

Prof. Fujima had been teaching a class on “Tsunami Damage Survey” inTsunami Disaster Mitigation Course since its beginning in 2006-2007 academicyear. Even in a cold windy day in winter, he pursued a field-survey practicearound the pond located on the BRI’s premise.
Also, from the academic year 2010-2011,“Introduction of Tsunami Disaster Mitigation.”

The then participants of Tsunami Disaster Mitigation Course would surely all
remember his practices and lectures.
We would like to extend the sincerest sympathy from all of us at IISEE to hisloss.
