From different sides the attempt has been made to get more information on the occurrence of earthquakes in general by examining the deep-focus earthquakes. These quakes seem to be different from ordinary ones no
743 shallow earthquakes, 651 intermediate-depth earthquakes and 281 deep-focus earthquakes (Fig.1). The STFs are first scaled byM_0^{\frac{1}{3}}in time and byM_0^{\frac{2}{3}}in magnitude to remove the moment
An unusually damaging Mw 4.9 earthquake occurred on November 11, 2019 in the south east of France within the lower Rhône river valley, an industrial region that hosts several operating nuclear power plants. The hypocentre of this event occurred at an
A distinct increase in PGA with Vs30 is observed for non-near field earthquake highlighting the proposed model captures the soil amplification characteristics. Variation of the PGA with respect to focal depth is also noted, with higher PGA for deeper focus (Fig. 10, bottom-left). Distinct ...
In situ laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was performed with a laser ablation system (Analyte Excite, Teledyne Cetac Technologies) coupled with quadrupole ICP-MS (7700x, Agilent Technologies) at Nanjing FocusMS Technology Co. Ltd., Nanjing, China. The 193-nm...
In the following, the focus will be set on small-scale sequence 13 in the sections of the Jura platform, which is part of the transgressive systems tract of sequence Be4 (Fig. 5). During this long-term transgression, accommodation on the shallow platform increased and allowed for a ...

Therefore, we will mostly focus our interpretation on the S-model. In this section, the seismicity is shown to be uniformly aligned in the Benioff zone. As shown in Supplementary Fig. 1B, this seismicity corresponds to a narrow belt that is presumably related to the subduction of the IFZ ...
Engineering considerations for urban projects focus mainly on the shallow depth for foundations. This includes the surface weathered layer and the bedrock. The surface layer in the area, as mentioned earlier is silty gravel with variable thickness throughout the area. The depositional characteristics of...
Triassic sedimentation in Singapore is represented by the Jurong Group, and overlying Sentosa Group, the former containing the focus of this study; the Pulau Ayer Chawan Formation. The Pulau Ayer Chawan Formation is considered to be Middle Triassic in age, and contains a single member: the ...
