Google Maps 17th International Symposium on Vulcanospeleology Aloha from our mid Pacific Polynesian island The small band of cavers on the Big Island of Hawai'i, together with a lar ger group of regular visitors, welcome you to attend the next Symposium of Vulcanspeleology on Hawaii in 2016. It will be the 25th anniversary of the last time the symposium was held in Hawai'i. In the past 25 years there have been some momentous discov eries here and we hope that many vulcanspeleologists will make the effort to see the world class lava tubes and other volcanic features active and dormant on the Big Island. We, the organizers, will do all we can to make your long trip very worthwhile. Since the symposium is 10 months away, plans can, and probably will, change. There will be updated information about accommodation s pre and post symposium activities, and cave trips offered during the symposium. We are giving you enough information now so you c an decide whether to attend and when to arrive and leave. If Ocean View is covered in lava, the symposium is off! Ann Bosted bosted@earthlink.net

LIMIT ON NUMBER OF ATTENDEES At the Galapagos symposium, when we proposed holding the next symposium in Hawai'i, we said that we would have to l imit the number or attendees to make the Ocean View venue workable and affordable. After careful consideration, we have set the limit at 80 attendees. As far as we know, no symposium has had more than 80 attendees, so hopefully this will not inconvenien ce anyone. However, it does mean that if you are planning to attend, you should register soon to avoid disappointment. Since t here is a limit, we ask that only those who plan to attend most talks and/or most cave trips should register. If you are traveling with a companion who is not interested in vulcanspeleology, perhaps you should encourage him or her to not register and to pursue other activities.

GETTING TO OCEAN VIEW The Big Island's two airports are equally convenient to Ocean View. There are direct flights to both Kailua Kona KOA and Hilo ITO from many cities on the mainland. If you are flying from other countries, you will likely have to fly through Honolulu and you may have to spend a night in the big city. From Honolulu you can fly to either Hilo or Kailua Kona. Both airports have car rental facilities. We prefer Kailua Kona as it is on the dry side of the island, it stays open longer and is generally cheaper. AIR QUALITY & HEALTH ISSUES When the prevailing Trade Winds blow, the town of Ocean View is down wind of the island's active caldera called Halema'uma'u, which has been spewing a plume of sulfur dioxide for about the last 6 years. P eople who suffer from bad asthma or other respiratory problems should consid er not attending the symposium. http://health.hawaii.gov/cab/files/2015 /02/kilauea_vog_faq january 2015b.pdf ORGANIZERS There are a few cavers living in Ocean View who are willing to put this event together. They are Peter & Ann Bosted, Ric Elhard & Rose Herrera, and John & Mary Wilson. Stephan Kempe, who lives in Germany and has attended most of the symposia, will be heavily involved and he takes respon sibility for organizing the papers and proceedings and keeping us all in line. Hilo caver, Steve Smith, Volcano volcanologist, Jack Lockwood and cave biologist Fred Stone of Kurtistown will all be supporting. We are counting on a huge number of cavers, w ho regularly cave on the island, to volunteer to lead field trips and help with the running of the symposium. THE CAVES The Big Island of Hawai'i is home to world class lava caves and many of them are in the Ocean View area. These amazing lava caves ar e the primary reason for holding the symposium in Ocean View. If you go to Bob Gulden's web site, you will see how heavily Hawaiian lava tubes feature in his list of the world's longest. Here is the link : http://www.caverbob.com/lava.htm

ACCOMMODATIONS Each attendee will be responsible for finding a place to stay and paying for it. We will provide a list of possible places and prices. If you come, you must choose a place that you like and pay for it independent ly of the symposium organizers. The exception is camping. The owner of the campground, a caver, Andreas Pflitsch, asked us to manage it, by arranging the bookings and collecting the fees. If you wish to camp in a yurt, please e mail bosted@earthlink.net to make arrangements. We are still finalizing a few of the details, so we will send out a circular devoted exclusively to lodging. Please be patient. When it does arrive, please study your options carefully to make sure you are getting a place that suits your needs and your budget. After doing a preliminary survey of vacation rental accommodation available in Ocean View, w e determined that there are about 100 beds available in about 35 homes, guest cottages, small homes or large houses. A rough calculation shows that a person could spend a week in Ocean View for an average cost of about $250, assuming double occupancy and a willingness to share large family homes with multiple bedrooms. In addition there are professi onal Bed and Breakfasts, plus camping in yurts or permanently parked camper vans. Again, we are encouraging attendees to share. It will save money and improve your social life. MISCELLANEOUS We will announce when the symposium web site is ready for reg istration. If you change your e mail address, please inform bosted@earthlink.net More detailed information about Ocean View and pre & post symposium activities was provided in a an e mail. If you d id not receive this e mail : FIRST CIRCULAR FOR THE 17TH SYMPOSIUM OF VULCANSPELEOLOGY please contact the Bosteds directly or anyone one of the newsletter editorial staff see page 2 We will be happy to forward that e mail directly to you.

From December 2013 to January 2015, the joint team of the Geological Museum of Vietnam belonging to the General Department of Geology and Minerals and NPO Vulcano Speleological Society of Japan carried out a survey for volcanic caves in the lava flowed from the Chu B luk Volcano located in the centra l Vietnam plateau in Dak Nong Province, CU JUT Prefecture. As a result of the survey, the joint team explored 18 lava tube caves, among which the measured total length o f the caves C2, C3, C4, C6, C61, C7, C8, C9 and A1 is 4832.5 m. The longest lava tube cave found is C7 which has a total length of 1066.5 m. Th e second longest cave is 967.8m of C3+C4 lava tube cave. The third longest Vietnam Volcanic Cave Survey by Tsutomu Honda and Hiroshi Tachihara NPO Vulcano Speleological Society, Japan

PAGE 13

cave is 791.0m of C8 lava tube cave. The sixth longest cave is 475.5 m of C0 lava tube cave. The seventh longest cave of A1 lava tube cave has a length of 438m. The eighth longes t cave of C2 lava tube cave has a length of 402.2m. So far the longest lava tube caves known from South East Asia since then was Hang Doi 1+2 Km 122 cave 549m and Hang Doi 1+2 Km 12 3cave 495m discovered by a team of speleologists from the German Spel eoclub Berlin and members of the Vietnam Academy of Sciences Institute for Tropical Biology in the Tan Phu area of Dong Nai Province. Consequently, Hang Doi 1+2 Km 122 and Hang Doi 1+2 Km 12 3 cave is fourth and fifth longest lava tube cave in South East Asia. Then, after C0, A1 and C2, Gua Lawa II cave in Indonesia will be nineth longest in South Eas t Asia. Vietnam hosts now eight longest lava tube caves in South East Asia. Total integrated length measured as a tube system of lava caves C2~C9 is 4393.8 m Also, it is worth to mention that the large lava tree mold is found on the surface of the inner side wall of C2 and C3 lava tube cave.

Gallardo Cave, Galapgos Islands Photo by Peter an d Ann Bosted Provisional Report 16th Symposium of the Commission on Volcanic Caves Galpagos 15th 22nd March 2014 Since I chairman of the commission Jan Paul was not present a t this symposium notes are based on the first E mails from participants. First many thanks to the organizers Theofilos Toulkeridis and Aaron Addison The number of participants was some 58, which is considerable. From a card I received I counted some 10 nationalities! As someone wrote: we had an adventurous meeting, many interesting caves, many nice people and many beers & Stephan Kempe et al will make an article abou t this symposium for the Journal of Cave and Karst Studies which is almost finished to be published, and Greg will also make a report for the commission, but later, as he has a very busy business program coming. During the commission meeting some interest ing points were reported: the long awaited book about caves of volcanic origin will come! This long time ago started project came to a halt by the untimely demise of Chris Wood. Now a concrete la y out is projected by Stephan Kempe, Greg Middleton and Paolo Forti. Also a publisher is in view. the next symposium of the commission will be in 2016 in Hawaii Ocean View.

Abstract This paper explores the environmental conditions that faced the people of ancient Jawa during the Holocene, as well as previous prehistoric periods of the mid late Pleistocene. Calcite speleothems in a lava tube are dated using the U Th method, to marine oxygen isotope stage 7 from "<250 to 240 ka and from "<230 to "<220 ka; and the stage 5/4 transition between "<80 and 70 ka. The available evidence indicates general aridity of the Black Desert during most of the mid late Quaternary, punctuated by short wetter periods, when the Mediterra nean cyclonic systems intensified and penetrated the north Arabian Desert. These Mediterranean systems had a longer and more intense effect on the desert fringe closer to the Mediterranean and only rarely penetrated the Black Desert of Jawa. The results do not exclude some increase of rainfall which did not change water availability dramatically during the warm Holocene. The ancient Jawa city appears to have depended on technological ability to build elaborate runoff collection systems, which became the pri me condition for success. 2008 University of Washington.

Holuhraun Eruption, Iceland December 2014 Photos by Phil Collett In December 2014 Phil Collett took a flight over the Holuhraun e ruption in a small aircraft. He described the flight as a "once in a lifetime event." Lava was erupting from a 400 metre section of the original 1.5 km fissure. A lava lake has formed over the fissure. Lava wa s being thrown above the surface of the lake in places. More of Phil's photos can be seen here: https://www.flickr.com/photos/pc_imag e/sets/72157647365802904/
