Seismic Waveguide of Metamaterials
, 2012 We have developed a new method of an earthquake-resistant design to support conventional aseismic designs using acoustic metamaterials. We suggest a simple and practical method to reduce the amplitude of a seismic wave exponentially.

Elastic properties of silicate melts: Implications for low velocity zones at the lithosphere-asthenosphere boundary. [PDF]
, 2017 Low seismic velocity regions in the mantle and crust are commonly attributed to the presence of silicate melts. Determining melt volume and geometric distribution is fundamental to understanding planetary dynamics.

Great East Japan Earthquake, JR East Mitigation Successes, and Lessons for California High-Speed Rail, MTI Report 12-37 [PDF]
, 2015 California and Japan both experience frequent seismic activity, which is often damaging to infrastructure. Seismologists have developed systems for detecting and analyzing earthquakes in real-time.

Anomalous surface waves from Lop Nor nuclear explosions: Observations and numerical modeling [PDF]
, 1998 Surface waves from the Chinese test site of Lop Nor are analyzed using long-period and broadband stations located at regional and teleseismic distances and at different azimuths. For most azimuths, strong Love waves between 0.02 and 0.045 Hz are observed

Extraction of Tsunami Signals from Coupled Seismic and Tsunami Waves
Journal of Marine Science and EngineeringThe generation of an earthquake and a tsunami is a coupled process of radiating seismic waves and exciting tsunamis, and the two types of waves are simultaneously recorded by ocean-bottom pressure sensors.

Seismic wave propagation in icy ocean worlds
, 2017 Seismology was developed on Earth and shaped our model of the Earth's interior over the 20th century. With the exception of the Philae lander, all in situ extraterrestrial seismological effort to date was limited to other terrestrial planets. All have in

Український антарктичний журналEarthquakes cause fluctuations in the surface of the geological environment, which may affect Antarctica’s ice sheet. As seismic waves interact with a glacier, more fissures appear, and its speed may increase. These processes may accelerate the reduction

Effects of Oblique Incidence of SV Waves on Nonlinear Seismic Response of a Lined Arched Tunnel
Shock and Vibration, 2020 The incident direction of earthquake motion is an important factor affecting the seismic response of underground structures. In this study, a three-dimensional (3D) oblique incidence method of SV waves is proposed and the effects of incident angles of SV
