SUMMARY:Underground seeing: characterization of geological hazard at the as
 tronomical observatories of the Canaries, Chile and Hawaii
DESCRIPTION:Underground seeing: characterization of geological hazard at th
 e astronomical observatories of the Canaries, Chile and Hawaii\nDr. Antoni
 o Eff-Darwich\n\nAn analysis of the impact of seismic and volcanic activit
 y was carried out at selected astronomical sites, namely the observatories
  of El Teide (Tenerife, Canary Islands), Roque de los Muchachos (La Palma,
  Canary Islands), Mauna Kea (Hawaii) and Paranal (Chile) and the candidate
  site of Cerro Ventarrones/Armazones (Chile). In this sense, we studied th
 e impact of seismicity, volcanic ash clouds, lava flows and ground deforma
 tion. Hazard associated with volcanic activity is low or negligible at all
  sites, whereas seismic hazard is very high in Chile and Hawaii. The lowes
 t geological hazard in both seismic and volcanic activity was found at Roq
 ue de los Muchachos observatory, in the island of La Palma.
