Earthquakes are the main mechanism by which elastic energy accumulating due to tectonic motion is released.

The calculation was based on the Qseis2006 code in the Fomosto tool of the Pyrocko package (Heimann et al., We performed a grid search through strikes between 80° and 160°, dips between 20° and 90°, rakes between We tested the best‐fitting focal mechanisms in Figure The ability of the synthetic waveforms to fit the data varies between stations.

They often cause catastrophes because they travel long distances at high velocity.

Meanwhile, to investigate the mechanism that produces the high mobility of loess landslides, ring shear tests were conducted on loess specimens with large shear displacement of up to several meters under the undrained condition, and it was found that the initial normal stress has no effects, and overconsolidation ratio has little if any effects, on the apparent friction angle in the steady state for loess soils. There were aftershocks for more than 3 years following this earthquake.

Destruction stretched across seven Chinese provinces.
To clarify the mechanism of these landslides, field survey was performed on the landslides triggered by the Haiyuan Earthquake (China, 1920), and a series of ring shear tests was conducted on the loess soils collected from a landslide.
If the microfilm did not contain a scale on the page, the record could only be used for epicenter relocation and focal mechanism determination but not for amplitude measurements.We first digitized the waveforms by hand as Bezier curves in version 2.10 of the GNU Image Manipulation Program (Due to the mechanical design of the seismographs, which involved a hinged stylus swinging on a rotating cylindrical drum, these analog waveforms have unwanted curvature and slant (Figure If we could not find damping information in literature and the seismograms did not contain the calibration pulse (e.g., AKIH, LPZH, and TACB), we chose as a best estimate the most common damping ratio of the same type of instrument in Wood (The station books and local bulletins that we sourced from individual contacts and obtained from the the Istituto Nazionale di Geofisica e Vulcanologia's EUROSISMOS project webpage (We then used version 6.0c of the Hyposat program package (Schweitzer, Three independent inversions were performed with arrival times from newly picked waveforms only, bulletins (previously published and newly added from station books readings) only, and the combined data, respectively. The records had to be long enough to contain the full body wave trains, be well‐damped, and, more importantly, be of known polarity (Kulikova & Krüger, To check if we could reproduce the body wave and surface wave magnitudes obtained by Gutenberg and Richter ((a) Overview of data coverage by Pleiades imagery (green outline) and drone imagery (black) in this study and LiDAR DEMs (pink) in Ren et al.

Some rivers were damned, others went off course, either way, it is a memory tat will haunt the survivors forever! - "Historic Earthquakes," Nov. 01, 2012.
