For the first time, from early 2019 to end of 2022, Mars’ shallow and deep interiors have been explored by seismology with InSight mission. Thanks performances its seismometers quality their robotic installation on ground, 1,319 seismic events detected, including about 90 marsquakes at teleseismic distances, Mw 2.5 4.7 least 6 impacts, largest ones craters larger than 130 m. A large fraction th...

Earth is inhomogeneous, which means its elastic characteristics change with depth. The seismic method employs the propagation of waves throughout the earth to locate different structures and stratigraphy. Understanding the wave propagation is an important matter in exploration seismology; therefore modeling of seismic wave is an important tool. To validate the interpreted earth model out of the...

It is well-known that the design and production of nuclear weapons required major efforts in scientific research and engineering, with a supporting infrastructure of weapons laboratories. Less well-known, is that scientific research and development have also played an important role in nuclear arms control. In this paper, my purpose is to explain the role of seismology in treaty verification; t...

Answering fundamental questions about the origin and evolution of small planetary bodies hinges on our ability to image their surface and interior structure in detail and at high resolution. The interior structure is not easily accessible without systematic imaging using, e.g., radar transmission and reflection data from multiple viewpoints, as in medical tomography. Radar tomography can be per...
