CVL Co-Leaders

Corentin Caudron and Jennifer Lewicki (2019-present)

Institut des Sciences de la Terre, Université de Savoie, France

US Geological Survey, Menlo Park, CA, USA

C.C. and J.L. were unanimously elected the new Leaders of CVL during the March 2019 CVL10 Workshop in New Zealand.


C.C. is CVL’s fresh spearhead for geophysical research, that has made our community broader and more multi-disciplinary in recent years. Revealing secrets from the emblematic Kawah Ijen crater lake (East Java), the largest of the hyper-acidic ones, is his laboratory and master. C.C. recent work is on the “anatomy of phreatic eruptions”. He organized the unique “Wet Volcanoes” Workshop in September 2014 at Kawah Ijen. C.C. is, together with T. Ohba and B. Capaccioni, co-editor of the volume on volcanic lakes (Geological Society of London). C.C. is a CVL SC member since 2013 and webmaster from 2016 to 2019.

J.L.’s experience in the study of fluid geochemistry and gas and heat emissions of hydrothermal systems (e.g., Yellowstone, Newberry Caldera, Mammoth Mountain, Masaya) has permeated into the lake realm since the 2014 Kawah Ijen “Wet Volcanoes” Workshop. J.L. is “new blood” to CVL. Jen pic.001

The entousiasm, multi-disciplinarity and young spirit of the new Co-Leaders will certainly attract new researchers to our growing community.






CVL Secretary

Bruce W. Christenson (2016-present, SC member since 2010)IMG_1993.jpg

Geological and Nuclear Sciences, Lower Hutt, New Zealand

B.W.C. is probably the most active researcher among the crater lake pioneers. His long-term experience, innovating and revolutionary ideas on Ruapehu and White Island, among many other volcanoes, are always illuminating and scientific corner-stones for our community. He is our guide in the acid lake business. Bruce witnessed and monitored the 1995-1996, 2006 and 2007 Ruapehu eruptions, Tongariro’s 2011 eruption and the recent eruption dynamics of White Island, which he started studying together with “the” fluid pioneer Werner F. Giggenbach. B.W.C. is co-author of the first Monograph on Volcanic Lakes (Springer, 2015). B.W.C., together with Agnes Mazot, organized CVL10-New Zealand in 2019.

Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Bologna, Italy


Together with Yuri Taran, D.R. studied the dynamic El Chichón crater lake (Chiapas, Mexico) during his M.Sc. and Ph.D. (2000-2006, UNAM, Mexico). In 2004, D.R. participated to his first CVL workshop at Copahue (CVL6-Argentina) and met with J.C. Varekamp. In 2006, Minoru Kusakabe asked D.R. to give a hand during his yearly Lake Nyos campaign. After his Ph.D. D.R. moved from Mexico to Italy, where he still works at INGV (Bologna). On request by J.C. Varekamp, D.R. co-organized CVL7-Costa Rica (2010) with R. Mora-Amador (UCR) and OVSICORI (M. Martínez), to get going with CVL_2.0. He is co-author of the first Monograph on Volcanic Lakes (Springer, 2015), and is currently editing the Special Issue on Lake Nyos (J. Afric. Earth Sci.).


Greg Tanyileke (2013-present, CVL Secretary 2013-2016)IMG_0174

Institut de Recherche Geologiques et Minières, Yaounde, Cameroon

G.T. is the Cameroonian pioneer on the infamous Lakes Nyos and Monoun. As the first Ph.D. student of Minoru Kusakabe (Misasa University, Japan) G.T. paved the road for the next generation of his Cameroonian colleagues. G.T. was the chief organizer of the CVL9 Workshop (March 2016). As a recognition for serving his country, during CVL9, G.T. received the title of Chevalier de la République du Cameroun, in name of the Cameroonian President, Paul Biya.



Agnes Mazot (2010-present)IMG_1998.jpg

Geological and Nuclear Sciences, Wairakei, New Zealand

A.M. was the first to make the CO2 accumulation chamber float on active crater lakes. From Indonesia to Italy passing Mexico, since 2008 she makes her chamber float on New Zealand’s volcanic lakes Rotomahana, Ruapehu, etc.  A.M., together with B.W.C., organized CVL10-New Zealand in 2019.



Franco Tassi (2010-present)IMG_0305

Università degli Studi di Firenze, Florence, Italy

F.T. put many unstudied volcanoes -with or without lakes- on the map with his complete fluid geochemical approach and style. F.T. is the most “limnological” and “wet” among the gas geochemists. Besides being a key CVL SC member, F.T. is the Leader of our “Sister Commission” IAVCEI-CCVG (2013-present). F.T. is tutor of many Italian, Chilean and Argentinan youngsters, creating a steady flux from below of great scientists to assure the future of both CVL and CCVG. F.T. is co-author of the first Monograph on Volcanic Lakes (Springer, 2015), of the Copahue volume, and, together with R. Mora-Amador and O. Vaselli of the Poás volume (2019) of the Springer IAVCEI Series Active volcanoes of the world.



Raúl Mora-Amador (2013-present)Raul.001

Universidad de Costa Rica, San José, Costa Rica

R.M.-A. is the guy who best knows Poás’ Laguna Caliente, arguably the most active crater lake on Earth: monthly visits for 20+ years now. His current research  focusses on physical and historical volcanology of Poás, besides the continuing monitoring efforts of Poás, Irazú, Rincón de la Vieja lake hosting volcanoes, Laguna Hule and Río Cuarto “Nyos-type” lakes, and Costarica’s currently most active volcano Turrialba. R.M.-A. was the chief organizer of the CVL7 Workshop (March 2010) and, together with F.T. and Orlando Vaselli, co-editor of the Poás volume (2019) of the Springer IAVCEI Series Active volcanoes of the world.



Jacopo Cabassi (2016-present)2016-03-22 13.51.01

Università degli Studi di Firenze, Florence, Italy

J.C. is the face of the “bio-activity lakes”, making CVL not only more “limno”, but also more “bio”. Together with F.T., J.C. tackles the European “Nyos-type” lakes one by one (Albano, Monticchio’s 2, Averno, Pavin, Laacher See, Azores’ many), in search for more than just inorganics. J.C. has organized Volcanic Lake summer schools in Italy.



Céline Mandon (2019-present) 


Yachay Tech University, Urcuqui, Ecuador

C.M. is new to CVL, but she enterred through the big gate by studying metal cycling through the most extreme and dynamic crater lake on Earth: Whakaari/White Island, sacred grounds of fluid pioneers B.W.C. and W.F. Giggenbach. Now in Ecuador, C.M. is preparing new research on Lakes Quilotoa and Cuicocha.



Akihiko Terada (2019-present)

Kusatsu-Shirane Volcano Observatory, TIT, Japan IMG_2000

A.T. follows up Takeshi Ohba as CVL SC member as well as the leader of the monitoring of  Kusatsu-Shirane’s infamous Yugama crater lake. A.T.’s recent studies on detailed mass and energy balances of crater lakes, and the first drone-borne lake water sampling were groundbreaking. His experience as a monitoring researcher will now seep through into CVL.



Maarten de Moor (2019-present)


OVSICORI-UNA, Heredia, Costa Rica

In his early years, M.dM. was tutored by two bigs in the fluid field, Joop Varekamp and Tobias Fischer. His classical formation mingled with high-tech gas measurements has led and will lead to major leaps forward in the study of degassing of acid species from crater lakes. His backyard in Costa Rica provides the most ideal sites to go for it: Poás, Rincón de la Vieja and other Central American crater lakes. M.dM. was the webmaster of our nephew commission IAVCEI-CCVG from 2014 to 2017.
