Greetings
Message from Chairman of the Organizing Committee
Dear all,It is a great pleasure to invite you to the IAVCEI 2013 Scientific Assembly in
Kagoshima city. Kagoshima city is one of the Kyushu's largest cities, and islocated across Kagoshima-bay only 8 km from the summit of Sakurajima
volcano which is one of the most active volcanoes in Japan.
We counted almost one thousand explosive eruptions at Sakurajima
volcano last year, and its activity continues, already counting 660 explosive
eruptions at the beginning of this August. You may experience ash-fallToshitsugu Fujii,
during the assembly because summer wind often brings ash cloud toward
Chairman of the Organizing Committee,
IAVCEI 2013
the Kagoshima city.
Emeritus professor of the University of Tokyo
Frequent historical eruptions have been recorded since the 8th century at
Minami-dake of Sakurajima volcano, and the last largest eruption occurred on 12th January, 1914. During this eruption, lava flow issued from one of the
fissures on the flank of Minami-dake was poured into the strait between Sakurajima and Osumi-peninsula, transforming Sakurajima from an isolatedisland to the part of the peninsula. The ash cloud drifted northeastward and fall out ash was detected even in Kamchatka. That was also the last largest
eruption we experienced within 20th century in Japan. Several centenary programs are scheduled by Kagoshima city during a period from 2013 to thecentennial anniversary of 2014, and this IAVCEI Scientific Assembly is a kind of kick-off event for the series of programs.
I would like to encourage many people from different countries to attend the Assembly and discuss broad aspects of research relevant to the study andunderstanding of volcanoes. I hope that all of you will take advantage of the beautiful location and the interesting volcanic setting.

Message from President of IAVCEI
Dear Colleagues,
On behalf of the IAVCEI Community, welcome to the 2013 IAVCEI Scientific
Assembly in Kagoshima, Japan. The scientific program for this Kagoshima
Scientific Assembly is an exciting and very comprehensive one, catering forvery diverse research interests. The organisers of the conference and thescientific program are to be congratulated on their dedicated and excellent
work in organising this conference in the aftermath of the massive Tōhoku
Ray Cas,earthquake and tsunami of 11th March, 2011, and the ensuing Fukushima
President of IAVCEI,
Monash University,
nuclear disaster. These extreme events have come on top of the impact ofMelbourne, Australia.
the ongoing global financial crisis, and therefore the IAVCEI international
community is very grateful to Japan, its people and its scientific community for hosting this meeting under the extremely difficult circumstances
experienced by all.
Japan is no stranger to extreme natural disasters, including major volcanic eruptions, volcanic related sector collapse and debris avalanche events, andearthquakes. Here in Kyushu, in southwestern Japan, one of its most active volcanoes, Sakurajima volcano erupts continuously on the doorstep of thehost city for the conference, Kagoshima. Sakurajima is a very active stratovolcano that appears to have grown on the ring fault of the Aira Caldera thatformed during a major explosive eruption about 22 ka. Not far away sits Mt Unzen, which erupted continuously from 1990 to 1995. On 3rd June 1992,
43 people, mostly Japanese media people, but including three volcanologists, Katia and Maurice Krafft and Harry Glicken, were killed by a block and ash
flow event. In 1792, a sector of the Mayuyama lava dome edifice of Mt Unzen collapsed, and generated a tsunami that is estimated to have killed 15,000
people. Conference participants have the opportunity to participate in fieldtrips to these iconic volcanoes and others.
Unlike AGU and EGU meetings, which occur every year, in more or less the same venue, and have developed a sameness about them, IAVCEI Scientific
Assemblies occur every 4 years in different, usually exotic locations, between the major IAVCEI General Assemblies, which are held as part of 4 yearly
IUGG General Assemblies. Because these two conferences allow IAVCEI to organize scientific symposia, workshops and meetings covering the spectrumof cutting edge volcanological, geochemical and geophysical research relevant to the study and understanding of volcanoes, they represent the twomost important international conferences for the IAVCEI community. These conferences provide opportunities to hear cutting edge volcanologicalresearch, to network with international colleagues and to welcome and encourage our young scientists to participate in the activities of the global
IAVCEI community. In more recent years, the Cities on Volcanoes conferences have also grown in importance, with a focus on the impact of volcanic
events on society, hazards, and civil management of volcanic crises. The IAVCEI and IUGG General Assemblies, like AGU and EGU conferences, bring
together the broader "geophysical" community to address scientific problems from an interdisciplinary approach, as well as allowing each member
association of IUGG, including IAVCEI, to present its own scientific program of symposia and workshops. They are enormously fruitful and insightful
meetings in allowing interaction between the volcanological community with the seismology, hydrology, cryospheric, atmospheric, oceanographic,
geodetic, and magnetism research communities. The next IUGG and IAVCEI General Assembly will be held in the beautiful city of Prague, in the Czech
Republic, in 2015, so be sure to make this a "must attend" meeting in your diaries.
Finally, I welcome you all as members of IAVCEI. You will all automatically become members of IAVCEI when you attend CoV7. This is free, but we invite
members to become donors to IAVCEI, to help it continue its numerous activities, including supporting conferences and the participation in these by
early career researchers and scientists from developing countries.
I invite you to visit the IAVCEI website to find out more about IAVCEI and its activities: http://www.iavcei.org

Venue and Access
About Kagoshima
Kagoshima is located at the southern tip of Kyushu, the southernmost of the four main islands in Japan. It has a warm climate and vast area spanning
600 kilometers from north to south. Situated in close proximity to China and South Korea, it has developed a unique history and culture due to economic
and cultural influences from East Asia, as well as from Europe via sea trade.
Kagoshima is one of the main food supplying regions of Japan, producing high quality agricultural and marine produce. It is also the only prefecture in
Japan that has rocket launching facilities.
With the Kyushu Shinkansen going into full operation since March 2011, Kagoshima became more accessible and the number of visitors and businesspeople doubled. It now takes 4 hour 19 minutes to travel from the JR Shin-Osaka station in Kansai to Kagoshima Chuo station on “Sakura”, the new
Shinkansen train. In addition, Kagoshima airport, the hub of southern Kyushu, has regular international flights from Taipei, Shanghai and Seoul, which
are in turn connected to nine major Japanese cities such as Tokyo, Osaka, and Nagoya, as well as eight islands of Kagoshima prefecture, via domestic
flight.
Kagoshima City welcomes you with its wonderful grandiose view of Sakurajima, an active volcano, right in front of the city center. The former has growninto a major city in southern Kyushu with a population of approximately 606,000 people. The various city sights can be accessed via the street trams andsight-seeing buses. With magnificent scenery and delicious local food, the warm southern hospitality will make your stay and unforgettable one.
The IAVCEI 2013 Scientific Assembly welcomes you to this charming city.

Hokkaido is situated at the junction of two arc-trench systems, the NE Japan and Kuril arcs, both of which have experienced intense volcanism
since late Miocene. We will visit central and eastern Hokkaido, where locates at the southern end of the Kuril arc. We will focus on various typesof younger volcanoes, calderas (Akan, Kutcharo and Mashu), a volcanic complex (Taisetsu-Tokachi volcano group), and post-caldera volcanoes(Me-Akan and Atosanupuri). These volcanoes have erupted tephra deposits that are widely distributed in Hokkaido. We will investigate these
deposits to reconstruct the eruption sequences and magmatic processes. In addition, we will climb Tokachi-dake and Me-Akan volcanoes
to investigate their respective structures. We will also focus on the snow-melt lahar associated with the AD 1926 eruption of Tokachi-dakevolcano, which caused severe hazards and killed 144 people.
The participants are required to book into a hotel at Asahikawa on July 13 (Sat.) and will be sharing rooms from July 14 to 18. Further details of
the field trip will be announced after the application process.

This trip will visit two active volcanoes, Unzen and Aso, in central Kyushu, southwestern Japan, to observe volcanic deposits and study theirimpacts on the residents around the volcanoes. The 1990-1995 eruption of Unzen volcano resulted in one of Japan’s largest volcanic disasters
in the 20th century. Shimabara city and its environs were damaged by repeated pyroclastic flows and lahars. We will climb the new lava dome,
visit the devastated area, and observe the 1991-1995 dome-collapse type block-and-ash pyroclastic-flow and lahar deposits. Furthermore, wewill examine older deposits around the volcano and discuss the growth history starting from 500 ka.
Aso volcano, located about 70 km ENE of Unzen, is one of the most beautiful caldera volcanoes in the world. The caldera, which is 25 km northsouth and 18 km east-west in diameter, was formed by four gigantic pyroclastic-flow eruptions from 270 to 90 ka. The post-caldera central
cones initiated their eruptive activity just after the last caldera-forming eruption and have produced large volumes of fallout tephra layers andlava flows. Nakadake volcano, the only active central cone, is one of the most active volcanoes in Japan. Its recent activity is characterized byash and strombolian eruptions and phreatic or phreatomagmatic explosions. This field trip will focus on the gigantic pyroclastic-flow deposits
related to the caldera formation and the explosive and effusive post-caldera activity of the volcano.
Field boots and gloves are needed for the new lava dome climb. Rain gear and sun protection cream are highly recommended.
Meeting place: JR Kumamoto Station (9:00) or Kumamoto Airport (9:45) on July 15.
Transportation from JR Kumamoto Station or Kumamoto Airport (July 15) to JR Kumamoto Station (July 19), round trip by ferryboat from

This field trip will visit Suwanosejima volcanic island, one of the most active volcanoes in Japan and sometimes called the "Lighthouse of East
China Sea." This volcano has been active for more than 50 years, with strombolian to vulcanian activities that emit ash and ballistic ejecta. We
will climb the summit of Mt. Otake, 799 m asl, to observe the current activities in the crater (very quiet as of October 2012). We will also visit
some of the geophysical monitoring sites in the proximal area and examine the deposit from the 1813 eruption, the larg

est known eruptionof this island. We will focus on some aspects of the proximal facies of the 1813 sub-plinian eruption, consisting of clastogenic lava flows andagglutinate, as well as the distal scoria-fall deposits.
We will take the local ferry “Toshima” from Kagoshima to Suwanosejima island. This boat will pass along the volcanic islands of the KirishimaRyukyu arc. We will return to Yakushima aboard the chartered boat “Nanashima 2,” which will go around Suwanosejima, allowing us to see
coastal volcanic deposits, and then cruise along the volcanoes of the Tokara islands toward Yakushima island; this area is one of the mostpopular natural heritage sites in Japan.
Note: The boat trip to Suwanosejima is frequently cancelled or its schedule changed due to bad sea conditions caused by typhoons. This field
trip may also be cancelled, even immediately before it starts, if there is a risk of the boat trip being cancelled due to stormy weather. Field boots
are needed for the climb. Rain gear and sun protection cream are also highly recommended. There are no shops and banks in Suwanosejima
island, only some drink vending machines. The trip fee covers all three meals (mainly Japanese-style seafood) and 4 liters of water daily.

Northeast Japan, a mature island arc, has many stratovolcanoes along with some other volcano types. Eighteen of these volcanoes are active.
Most of the stratovolcanoes in NE Japan are thought to follow a general evolutional course consisting of (1) cone building, (2) caldera collapse,and (3) post-caldera stages. We will visit the following six active volcanoes and observe the geologic features of their activities during various
evolutional stages: the Iwate volcano, which is in the cone-building stage; the Bandai volcano, which is in the caldera-forming stage; and the
Azuma, Zao, Akita-Yakeyama, and Hachimantai volcanoes, which are in the post-caldera stage. The latest eruptions took place in AD 1888 at
Bandai, in AD 1977 at Azuma, in AD 1940 at Zao, in AD 1919 at Iwate, and in AD 1997 at Akita-Yakeyama. Among these, the 1888 eruption
in Bandai is famous for a sector collapse that accompanied a debris avalanche phenomenon, which was the first ever reported in the world.
Around Akita-Yakeyama, one can enjoy a spectacular view of a geothermal field. We will also visit Ichinomegata maar (80 to 60 ka), whichfeatures mantle xenoliths, and the Toga tuff ring.

This trip visits two topographically and petrologically contrasting active volcanoes in the Izu islands, the basaltic Izu-Oshima and the rhyolitic
Niijima volcano. Izu-Oshima has erupted more than a hundred times during the last 20,000 years. Its latest 12 eruptions in the past 1,500 years,
including the caldera formation, have been well investigated. We will view a spectacular tephra sequence, the caldera topography, and a chainof fissure vents. In view of the continuing inflation of the volcanic edifice on the island, we will visit the well-equipped observation stations andsee how data are monitored in preparation for any forthcoming eruption. Niijima volcano consists of more than 16 rhyolite lava domes. The
recent products of dome-building eruptions, such as pyroclastic surge and flow deposits, fallout pumice, and dome lava, are exposed along thesea cliff and quarry. We will closely observe the pyroclastic materials and their depositional structures, which suggest eruptions in the shallow

The Kikai caldera is one of the most active volcanoes in Japan. Most of the caldera is now submerged except for two major islands, Satsuma
Iwo-jima and Take-shima. The last caldera-forming eruption, called the “Akahoya eruption,” occurred 7,300 years ago. This eruption produced
voluminous pyroclastic flows (Koya ignimbrite) and widespread ashfall (Akahoya ash), which had devastating impacts on the culture andnatural environment of western Japan. After this eruption, new volcanoes formed inside the caldera through bimodal magmatism. One ofyoung silicic cones, Iwo-dake, has continued to emit volcanic gases for hundreds of years. On this field trip, we will visit Satsuma Iwo-jima islandand southern Kagoshima area to observe the eruptive products from the Kikai caldera, mainly focusing on pyroclastic deposits (plinian fallouts
and ignimbrites with various lithofacies) from the Akahoya eruption, and young tephra and lava flows from post-caldera volcanoes. Two young
volcanoes (the silicic Iwo-dake and the basaltic Inamura-dake) in Satsuma Iwo-jima island make for a spectacular scenery. The recent activities,
deposits, and current landscape represent the evolution of a large silicic magmatic system beneath the sea. We will also visit silicic pyroclastic
deposits from the Ikeda caldera in Ibusuki area.
Note: Stay at a Minshuku (Japanese-style accommodation) in Satsuma Iwojima island. The final schedule will be decided depending on theweather and sea conditions, which are basically good during this season, except for occasional typhoons.

The Kamchatka peninsula hosts a highly active and explosive volcanic arc, which forms the northwestern part of the Pacific Ring of Fire. Our
field excursion will concentrate on the Holocene volcanism, with a special focus on recent tephra deposits. The highlights of the excursion
include trips to the most active and prolific volcanoes of the arc. Near the city, we will be able to see the Avachinsky and Koriaksky "homevolcanoes" and examine their Holocene deposits. Then we will drive 500 km northward toward the Kliuchevskoi volcanic group, which
comprises the largest Kamchatka volcanoes. Kliuchevskoi (4850 m asl) is one of the most productive volcanoes on Earth, erupting an averageof about 90 Mt of magma every year. Ash clouds shooting from the volcano reach an altitude of ~20 km and regularly affect the air traffic
between SE Asia and North America. Tephra from Kliuchevskoi, as well as other volcanoes, has been accumulating on its slopes over thelast 12 kyr at a rate of ~1 mm/yr. This tephra sequence represents one of the longest and highest resolution record of explosive volcanism
in Kamchatka. We will examine tephra deposits and visit a number of Kliuchevskoi’s flank cinder cones and their lava flows. Then we will goto the Tolbachik monogenetic lava field, from where we can climb Plosky Tolbachik volcano (3085 m asl) to see its summit caldera and thenvisit the cinder cones and lava flows of the monogenetic field, including those formed during the 1975 eruption. The trips will be guided byvolcanologists from the Kamchatka Institute of Volcanology and Seismology.
Air carriers from Japan to Kamchatka: Vladivostok Airlines to Vladivostok, overnight stay, and then proceed to Petropavlovsk-Kamchatsky.
