FDSN Network Information

FDSN code YK (2000-2002) Operated by Eidgendssisch Technische Hochschule (ETH Zurich) - Swiss Seismological Service
Network name Coordinated Seismic Experiment in the Azores (COSEA) Deployment region Switzerland
Start date Jan. 1, 2000 End date Dec. 31, 2002
Short description

A 5-station broadband array (STS2 w/Reftek dataloggers) provided
by DTM, installed with help from ETH, and Instituto Metreorologia, Ponta
Delgada, Azores, Portugal was in operation from December 2000 - September
2002. Site locations selected to utilize existing stations operated by the
Portuguese (CMLA (an IRIS/GSN station) and CDRO (operated by Centro de
Geofisica da Universidadede Lisboa)) and French (FLOR (operated by Institut
de Physique du Globe de Paris)); placed on both sides of the mid-Atlantic
ridge; and as a westward extension of the MIDSEA experiment. This
deployment is aimed at understanding a) the Azores plume (the crust and
upper mantle structure); b) the behavior of the boundries between Eurasia,
Africa, and North America; and c) monitoring local seismic and volcanic
activity for improved natural hazards assesment.
