Station COI: Dusting Off an Old Seismic Station

Monitorização da variação secular dos parâmetros climatológicos em Coimbra: o caso da precipitação para análise de riscos hidrológicos

“…As Os trabalhos de sismologia iniciaram-se na última década do século XIX mas foi com a instalação do pêndulo horizontal de Milne, em 1903, que o registo sismológico 20 se passou a fazer de forma regular (Custodio et al, 2012) Por precipitação entende-se qualquer fenómeno de queda de água do céu, independentemente do seu estado físico, incluindo por isso chuva, neve e granizo.…”

The importance of scientific data and historical heritage of the geophysical and astronomical observatory of coimbra university for the study of geophysical sciences

“…4.4 | Seismic data collection seismic recording began regularly at the IGGUC only in May 1903, with the installation of a horizontal pendulum Milne (e.g., Custódio et al, 2011Custódio et al, , 2012. Since then, the Coimbra station became part of the first international seismological network that inaugurated the era of instrumental seismology, and its observations were integrated into the seismic catalogue of the International Association of Seismology for the year 1904 (Table 1).…”

“…Due to the continuous recording of telluric activity at IGUC and the updating of instrumentation done over the years, the seismological collection is well illustrative of the historical evolution of this scientific area. In the OGAUC are present all the types of equipment used on the record of seismic activity since 1903: a Milne seismograph, a Wiechert E-W and N-S horizontal seismograph, a Wiechert vertical seismograph, a Grenet seismograph, three Geotech S13 seismographs, three Geotech SL210 seismographs, a Streckeisen STS-2 (Custódio et al, 2012; Table 3). Alongside, the OGAUC has many thousands of records made by these instruments in its collection.…”

“…; Figure 2). However, this vast collection is mostly in print/analogue format (e.g., Custódio et al, 2010, 2012; Gomes & Lopes, 2017; Leonardo, Custódio, et al, 2013; Leonardo et al, 2011b; Morozova & Valente, 2012; Ribeiro et al, 2011). In addition, there is a vast technical‐scientific collection of reports, memoranda, books, scientific journals, notebooks (Figure 2), and instruments.…”
