Earthquake 3d Enhanced Edition V355
Earthquake 3D provides a fascinating look at recent seismic activity around the globe. While the program provides a great deal of information and options, it suffers from its complete lack of direction. We were initially impressed with the interface. The controls all looked basic, but soon we discovered that the Help file didn't do more than give a description of the product, and some actions we wanted to perform were not intuitive enough.
Observation-Driven Method Based on IIR Wiener Filter for Microseismic Data Denoising. 
Enhanced refractor imaging by supervirtual interferometry. Domain and its.
The program itself was a spinning globe with magnitudes and the traditional multiring circles indicating earthquakes. We appreciated how the control panel let us filter quakes by severity and changed the globe's look to better see the quakes. This all functioned great, but zooming in was impossible. We learned with ease how to rotate the globe using our mouse, but could not get a closer look, even though it's the first thing the description promised.
After several fruitless minutes we grew frustrated and gave up. On a more interesting note, the program did have a feature that updated the globe with the newest quakes. But this wasn't enough to rescue this program from its unfortunate lack of direction.
Earthquake 3D is a freeware program. The program comes as a compressed file. Even though we loved most aspects of this program, its lack of direction makes it hard to recommend.

The 2011 Tohoku earthquake (M w = 9.1) highlighted previously unobserved features for megathrust events, such as the large slip in a relatively limited area and the shallow rupture propagation. We use a Finite Element Model (FEM), taking into account the 3D geometrical and structural complexities up to the trench zone, and perform a joint inversion of tsunami and geodetic data to retrieve the earthquake slip distribution. We obtain a close spatial correlation between the main deep slip patch and the local seismic velocity anomalies, and large shallow slip extending also to the North coherently with a seismically observed low-frequency radiation.
These observations suggest that the friction controlled the rupture, initially confining the deeper rupture and then driving its propagation up to the trench, where it spreads laterally. These findings are relevant to earthquake and tsunami hazard assessment because they may help to detect regions likely prone to rupture along the megathrust, and to constrain the probability of high slip near the trench. Our estimate of ~40 m slip value around the JFAST (Japan Trench Fast Drilling Project) drilling zone contributes to constrain the dynamic shear stress and friction coefficient of the fault obtained by temperature measurements to ~0.68 MPa and ~0.10, respectively.
On March 11 th 2011 one of the largest earthquakes ever recorded occurred at the subduction interface between the Pacific and the Okhotsk plates and struck the Tohoku region in Japan (). This M w9.1 earthquake, located at 142.68°E 38.19°N, generated a tsunami that devastated the Japanese coasts, including towns and important infrastructures such as the Sendai airport and the Fukushima nuclear power plant causing more than 16,000 fatalities. The Tohoku earthquake is also the best observed ever megathrust event and consequently it has been investigated by modelling the unprecedented high-quality data set recorded by the Japanese dense seismological, geodetic and marine observational networks. The numerous studies published in recent literature are based on different kind of data and methodologies, including teleseismic, strong motion, geodetic,,, tsunami waveforms,, and joint inversions,, which were performed to investigate the earthquake rupture process.
