    Article
    Open Access
    This work describes a system-level overview of a multi-frequency GBSAR built around a high performance software defined radio (SDR). The main goal of the instrument is to be employed as a demonstrator and experimental ...

  • Detection of volcanic unrest onset in La Palma, Canary Islands, evolution and implications 

    Escayo Menéndez, Joaquín; Hu, Zhongbo; Mallorquí Franquet, Jordi Joan (Nature, 2021-12-01)
    Article
    Open Access
    La Palma island is one of the highest potential risks in the volcanic archipelago of the Canaries and therefore it is important to carry out an in-depth study to define its state of unrest. This has been accomplished through ...
