The first full meeting of the AlpArray Gravity Research Group is taking place on March 8-9 in Bratislava. This gathering of 16 participants discusses the group organization, data availability and homogenization, processing, research topics as well as collaborations among the group and with other groups.

The abstract submission and registration for the Himalaya-Karakorum-Tibet workshop (10-12. September, Lausanne) is now open until end of April. Visit the conference website for the second circular and detailed information, including the logistics and the registration page.

This week Shiba Subedi is participating at the Discussion Workshop on Educational and Citizen Seismology in London. Beyond presenting his own project, it is a great opportunity to learn about ongoing activities and the latest news of instrumentation for a branch of seismology that reaches far beyond researchers.

Next week will be the “Journées Biennales des Géosciences et de l’Environnement” at UNIL. It is a French-speaking event to bring together academic, governmental and private research on the broad topic of Earth sciences. On Wednesday the 14th of February will be the session La recherche fondamentale et appliquée en géologie. On Thursday will be held the 3rd meeting day of natural dangers, running under the title “Au-delà de l’aléa”, ou comment proposer une gestion intégrée des risques naturels?

The first full meeting of the AlpArray Receiver Function Working Group will be hosted by our group on January 29-30, 2018. Planning to gather 18 participants representing almost all institutions of the working group, we will discuss research topics, methods, tools, as well as collaborations among the group and with other groups.

The 2017 Fall Meeting of the AGU is taking place this week in New Orleans. Our group member’s contributions:

• Alvizuri CR, Hetényi G (S43B-0843) Seismic full moment tensors for events in the Indian lower crust beneath the Himalayas and their relevance to eclogitization
• Alvizuri CR, Tape C (S43H-2965) Full moment tensors with uncertainties for the 2017 North Korea declared nuclear test and for a collocated, subsequent event
• Tape C, Alvizuri CR, Silwal V, Tape W (S44B-01) Uncertainties for seismic moment tensors and applications to nuclear explosions, volcanic events, and earthquakes
• Colavitti L, Hetényi G (S51D-0633) Towards a new technique to construct a 3D shear-wave velocity model based on converted waves
• Pilet S, Müntener O, Duretz T, Hetényi G (V43G-07) Evidence for refertilization of the Pacific plate: implications for the seismic and geochemical properties of the oceanic lithosphere
• Hetényi G, Pistone M, Nabelek PI, Baumgartner LP (V24B-02) South-Tibetan partially molten batholiths: geophysical characterization and petrological assessment of their origin

Although not really a geoscience topic, everyone working in the Himalaya has heard of the famous and notorious yeti.

If you have and are interested and concerned, here are some important news…

The 15th Swiss Geoscience Meeting is held in Davos on November 17-18. Our group will present the following posters:

• Scarponi M, Hetényi G, Plomerová J, Solarino S, Berthet T, Baron L (2017) High resolution imaging of the Ivrea Geophysical Body: A receiver function and gravity approach.
• Hetényi G, Pistone M, Náb?lek PI, Baumgartner L (2017) Lhasa Block partial melt zones: matching geophysical characteristics and petrological origin.
• Hetényi G, Molinari I, Clinton J, Kissling E, Alparray Seismic Network Team, Alparray OBS Cruise Crew, Alparray Working Group (2017) The completed AlpArray Seismic Network.

The German component of the AlpArray program runs under a special program (SPP) of the German Science Foundation, under the title Mountain Building Processes in 4D. The first annual meeting was held in Potsdam on November 9-10, and hosted all German participants (and more) as well as a number of international AlpArray colleagues. More information on MB-4D can be found on their website: www.spp-mountainbuilding.de
