1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Zacharie Duputel <duputel@xxxxxxx> Dear Colleagues, The Piton de la Fournaise Volcano Observatory of the Institut de Physique du Globe de Paris invites applications for a postdoctoral researcher in the framework of the ERC PRESEISMIC project. The postdoctoral research will focus on the use of machine learning techniques to improve detection and localization of earthquakes during seismic swarms. Seismicity is currently one of the best tools to monitor transient aseismic processes such as slow slip on active faults or magma migration on volcanoes. However, given the large number of earthquakes to be identified and the increase in the number of available stations, automated approaches are necessary. The successful candidate will test the ability of existing deep neural network picking techniques to detect and locate earthquakes during active swarm episodes observed on volcanoes and on active faults. As a first application case, we intend to analyze pre-eruptive volcano-tectonic swarms at Piton de la Fournaise volcano to characterize the spatio-temporal properties of magma migration in the volcanic edifice. Funding is guaranteed for 18 months starting at the end of 2022 or early 2023. A recent Ph.D. in Geophysics (defended less than two years ago) and experience with the analysis of seismological data are required. Some skills in machine learning and in python are also highly desired. A driver's license is recommended. The candidate will be invited to participate in the fieldwork at Piton de la Fournaise volcano. He/she will also be invited to participate to the routine set up at the observatory for the monitoring of Piton de la Fournaise and Mayotte. The postdoctoral research will be conducted at the Piton de la Fournaise Volcano Observatory (OVPF) located on La Réunion Island. The observatory is in charge of monitoring the Piton de la Fournaise volcano since 1979. Since 2020, the OVPF is also in charge of monitoring the seismo-volcanic activity of Mayotte. The successful candidate will be integrated within a small but multidisciplinary active team of researchers working on one of the most active volcanoes on the planet (with more than 2 eruptions / year since 2014). The Observatory is located on La Réunion island, a hotspot of cultural diversity with nearly 1 million people. Application documents: The application must be made via the CNRS job portal ( https://urldefense.com/v3/__https://t.co/VclQhlK7pQ__;!!IKRxdwAv5BmarQ!ft722QZVDqo_Zd6ltgqaMvrOCpMtI1V7rnoCLgnG78vtUcfxkIfLRgkoeuvHsXd_utTxsYH1u25MUWCUp9iW$ ). Please attach a cover letter, a CV and the names of two references who may be contacted for letters of recommendation. Please contact Zacharie Duputel (duputel<at>ipgp.fr), Lise Retailleau (retailleau<at>ipgp.fr) and Valérie Ferrazzini (ferraz<at>ipgp.fr) for more information. 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
