Abstract We discovered a secular change in the travel time of direct S-waves over a 10-year observation period by means of continuous operation of an artificial and stable seismic source, called Accurately Controlled Routinely Operated Signal System

Monitoring the temporal variation of physical properties around the plate boundary region is important for detecting subtle changes before the occurrence of a large earthquake. Accurately controlled routinely operated signal system (ACROSS) is a powe

Development of a powerful stacking technique is important in the active monitoring in order to effectively enhance a signal-to-noise ratio (SNR) by utilizing not only quiet nighttime data but also noisy daytime data. Here we propose a stacking techni

To examine the usefulness of the accurately controlled routinely operated signal system (ACROSS) for the detection of the temporal change of scattering or reflection signatures, we conducted a 9-month experiment using a seismic ACROSS source in Toki

We have developed a new controlled electromagnetic source method called the EM-ACROSS (electromagnetic—accurately controlled routinely operated signal system) for monitoring of the electrical state in the ground. The basic idea of the EM-ACROSS sys

Temporal variations of Green functions associated with the eruptive activity at Sakurajima Volcano, Japan, were estimated using an accurately controlled routinely operated signal system (ACROSS). We deconvolved 400 s waveforms of the ACROSS signal at
