Seismic Observation by the Wiechert Seismograph at Abuyama Observatory

Automatic classification of seismic events within a regional seismograph network

The NEPTUNE observatory as seismic warning system

It is proposed to install an underwater observing system off the coast of Seattle, Washington and Vancouver, British Columbia in order to allow long-term scientific study of the ocean. The area to be covered corresponds to the Juan de Fuca tectonic plate. Electric power will be provided via a cable similar to a submarine telecommunications cable, and communications will be via fiber optics in t...

GRBs Optical follow - up observation at Lulin observatory , Taiwan ( ∗ )

— The Lulin GRB program, using the Lulin One-meter Telescope (LOT) in Taiwan started in July 2003. Its scientific aims are to discover optical counterparts of XRFs and short and long GRBs, then to quickly observe them in multiple bands. Thirteen follow-up observations were provided by LOT between July 2003 and Feb. 2005. One host galaxy was found at GRB 031203. Two optical afterglows were detec...

The Monterey Bay broadband ocean bottom seismic observatory

We report on the installation of a long-term buried ocean-floor broadband seismic station (MOBB) in Monterey Bay, California (U.S.A.), 40 km off-shore, at a water depth of 1000 m. The station was installed in April 2002 using a ship and ROV, in a collaborative effort between the Monterey Bay Aquarium Research Institute (MBARI) and the Berkeley Seismological Laboratory (BSL). The station is loca...

Seismic Observation of Solar Tachocline

Helioseismology has established the existence of a layer of strong gradients of angular velocity at the base of the solar convection zone. This layer (`tachocline') separates the convection zone exhibiting a strong latitudinal differential rotation from the radiative interior that rotates almost rigidly. Turbulence generated in the tachocline is likely to mix material in the upper radiative zon...
