La terra ha tremato alle 18.21 nei pressi di Thusis, nei Grigioni. Un terremoto di magnitudo 3.6 è stato registrato dai sismografi del Servizio sismico svizzero al Politecnico di Zurigo. Secondo quanto comunicato, una scossa simile è tale da essere percepita dalla popolazione in un'area piuttosto vasta, ma di regola non abbastanza forte da provocare danni.
In territorio elvetico o nelle vicinanze dei confini svizzeri si verificano ogni anno dai 1'000 ai 1'500 terremoti, dai tre ai quattro al giorno quindi, ma solo una decina o una ventina raggiungono almeno magnitudo 2.5 e possono quindi essere avvertiti.
