1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Roberto Isaia <roberto.isaia@xxxxxxx> Dear colleague, this is to inform you that the *Deadline* to contribute to the Research Topic of Frontiers in Earth Science has been has been *Extended to 8 March 2021*. *Multidisciplinary investigations for the definition of structure and dynamics of active volcanic system**. *(editors R. Isaia, M.G. Di Giuseppe, J. Gottsmann, M. Stock and A. Troiano) *â??**The objective of this Research Topic is to collect papers that draw on aspects of volcanology, geophysics, petrology and/or geochemistry to provide new information about the structure and dynamics of active volcanic and magmatic systems. These might include laboratory, field-based, experimental or modelling studies, which elucidate the architecture of volcanic systems on spatial scales ranging from surface observations to the entire crust, and temporal scales ranging from real-time monitoring during eruptive events to millennial eruptive histories. Original Research, Methods and Reviews integrating multiple geo-volcanological, geochemical and geophysical techniques are particularly encouraged, as well as examples showing how a more defined knowledge of volcanic structures can aid risk modelling and the estimation of volcanic hazards**â??.* To see the call detail click here: https://www.frontiersin.org/research-topics/15161/multidisciplinary-investigations-for-determining-the-structure-and-dynamics-of-active-volcanic-syste For any other information or detail please contact me or co-editors. *NEW Extended Deadline Manuscript submission* *08 March 2021* Hoping to hear from you soon, I wish you all the best. 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ------------------------------
