[1] This paper investigates the shallow seismicity occurring in the Taiwan region during the 20th century using a stochastic declustering method that has been developed on the basis of the theory of the epidemic-type aftershock sequence model. It provides a probability based tool to objectively separate the space-time occurrences of earthquakes into a background and a clustering component. On t...

The 1999 Izmit earthquake (17/08/1999, Mw=7.4) was one of the largest earthquakes to occur in northwestern Turkey during the past 100 years. This earthquake occurred along the Izmit-Sapanca fault within the Northern Anatolian Fault Zone. Variations in the generalized fractal dimensions (Dq) of clustering in time and space, the Gutenberg-Richter b value, and earthquake frequency (N) are evaluate...

The 2015 Gorkha Nepal earthquake caused tremendous damage and loss. To gain valuable lessons from this tragic event, an earthquake damage investigation team was dispatched to Nepal from 1 May 2015 to 7 May 2015. A unique aspect of the earthquake damage investigation is that first-hand earthquake damage data were obtained 6–11 days after the mainshock. To gain deeper understanding of the observe...

The frequency–magnitude statistics of 6527 earthquakes with 1.0 ≤ ml 5.7 and focal depths between 0 49 km in the Red Sea region 1980 2021 show that threshold magnitude, above which most are precisely located, is 1.5. b-value, identifies regional stress situations associated energy release modalities, has a value 0.75, less than historical data, averages 0.4 0.85 as it varies over time, indicati...

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

background: to check the feasibility of using geographical information system (gis) methods, we linked the brucellosis data of human and animals. methods: in a village-based ecological study in bardsir- a district in kerman province located nearly to the central part of iran- data of human brucellosis, socio-economic level, and livestock characteristics (2001-4) were linked by using gis methods...
