earthquakes travel times inversion for determination of velocity structure of crust is one of the most important objectives in seismology. in the simultaneous inversion method, the parameters of earthquakes and velocity model are determined initially and are improved during inversion steps. in this study, we have used more than 22000 calculated travel times for first arrivals of 6000 earthquake...

The Hawaiian "honeyeaters," five endemic species of recently extinct, nectar-feeding songbirds in the genera Moho and Chaetoptila, looked and acted like Australasian honeyeaters (Meliphagidae), and no taxonomist since their discovery on James Cook's third voyage has classified them as anything else. We obtained DNA sequences from museum specimens of Moho and Chaetoptila collected in Hawaii 115-...

Ambient noise correlation is now widely used in seismology to obtain the surface 6 waves part of the Green's function. More difficult is the extraction of body waves from noise 7 correlations. Using 42 temporary broad-band three components stations located on the 8 northern part of fennoscandian region, we identify high frequency (0.5-2 Hz) body waves 9 emerging from noise correlations for inte...

The Moho discontinuity is one of the fundamental boundaries on Earth, separating crust from upper mantle. Arrival times seismic reflection and refraction data are used to estimate depth Moho, but nature remains illusive. We present a synthetic seismogram modelling study for suite possible velocity models oceanic lower transition zone (MTZ). For modelling, we have 45-km long multichannel streame...

This study aims to determine Curie point depth (CPD), Heat flow and the boundaries of geological structures Cyprus Island using EMAG2 magnetic data. CPD values were calculated by applying spectral analysis technique anomaly map divided into 60 blocks (60x60 km2). Then, different thermal conductivity (K=1, 1.5 2.5 Wm–1 K–1) heat values. ranged from 12.4 km 28.18 km, between 20 50 mW/m2 for K=1. ...

Crustal rejuvenation is a key process that has shaped the characteristics of current continental structures and components in tectonic active continental regions. Geological and geochemical observations have provided insights into crustal rejuvenation, although the crustal structural fabrics have not been well constrained. Here, we present a seismic image across the North China Craton (NCC) and...
