We performed oceanic and atmospheric observations in the region off the Sanriku coast, Japan, from May 11 to 5 July 2022, using a wave-propelled unmanned surface vehicle, a Wave Glider (WG). Despite the severe weather conditions of atmospheric low-pressure system crossings, we successfully measured wind, air temperature, humidity, and sea surface temperature over the course of 55 days to calculate the turbulent heat flux. The WG observed that the atmosphere became more humid due to the southerly wind along the northwestern rim of the North Pacific subtropical high.

- The 2011 Tohoku-oki earthquake was the largest recorded using seafloor geodetic techniques, revealing significant crustal movements during and after the event.
- New results from a nearly four-year study using Global Positioning System (GPS) and acoustic measurements show varying postseismic displacement rates along the Japan Trench, highlighting different geological processes at play.
- These findings enhance our understanding of viscoelastic relaxation and afterslip behavior, which are crucial for improving seismic hazard assessments in the affected region.
