Broadband modeling of local earthquakes [PDF]

open access: yes, 1990
Three-component broadband waveforms of two small earthquakes near Upland, California, recorded on the Pasadena broadband, high dynamic range instrument, were modeled to obtain useful Green's functions for this path and to examine the sensitivity of the ...

Estimates of regional and local strong motions during the great 1923 Kanto, Japan, earthquake (Ms 8.2). Part 1: Source estimation of a calibration event and modeling of wave propagation paths [PDF]

open access: yes, 1998
This article is the first of a pair of articles that estimate regional and local strong motions from the 1923 Kanto, Japan, earthquake. This Ms 8.2 earthquake caused the most devastating damage in the metropolitan area in Tokyo history.

Predictability of strong ground motion in the Imperial Valley: Modeling the M4.9, November 4, 1976 Brawley earthquake [PDF]

open access: yes, 1978
Strong-motion displacements, recorded at 33 km (IVC) and 36 km (ELC) from the November 4, 1976 Brawley earthquake, are modeled using the Cagniard-deHoop technique.

Approximation of Rupture Directivity in Regional Phases Using Upgoing and Downgoing Wave Fields [PDF]

open access: yes, 1997
Recent broadband modeling of regional events suggests that vertical directivity is particularly important at high frequency. Conventionally, such directivity is obtained by summing a grid of point sources.

Noncollinearity-modulated electronic properties of the monolayer CrI$_3$

open access: yes, 2019
Introducing noncollinear magnetization into a monolayer CrI$_3$ is proposed to be an effective approach to modulate the local electronic properties of the two-dimensional (2D) magnetic material. Using first-principles calculation, we illustrate that both

Faulting process of the May 17, 1976 Gazli, USSR earthquake [PDF]

open access: yes, 1980
The May 17, 1976 Gazli earthquake (m_b = 6.2, M_s = 7.0) has both seismological and engineering importance. Waveform modeling of long-period IDA Rayleigh waves, and WWSSN long- and short-period body waves indicates a thrust mechanism with strike N40°E ...

Unusual spacecraft materials [PDF]

open access: yes
For particularly innovative space exploration missions, unusual requirements are levied on the structural components of the spacecraft. In many cases, the preferred solution is the utilization of unusual materials.

MECA Workshop on Atmospheric H2O Observations of Earth and Mars. Physical Processes, Measurements and Interpretations [PDF]

open access: yes
The workshop was held to discuss a variety of questions related to the detection and cycling of atmospheric water. Among the questions addressed were: what factors govern the storage and exchange of water between planetary surfaces and atmospheres; what
