Anisotropic structure beneath central Java from local earthquake tomography

P-wave velocity structure of the crust and uppermost mantle beneath Iceland from local earthquake tomography

The structure of the crust and uppermost mantle beneath Iceland, the keys to understanding the magma plumbing system of the hotspot and hotspot–ridge interaction, was poorly constrained in previous seismological investigations. Here we develop a three-dimensional P-wave velocity model of the Icelandic crust and uppermost mantle from tomographic inversion of over 3500 first-arrivals from local e...

Subduction-zone structure and magmatic processes beneath Costa Rica constrained by local earthquake tomography and petrological modelling

S U M M A R Y A high-quality data set of 3790 earthquakes were simultaneously inverted for hypocentre locations and 3-D P-wave velocities in Costa Rica. Tests with synthetic data and resolution estimates derived from the resolution matrix indicate that the velocity model is well constrained in central Costa Rica to a depth of 70 km; northwestern and southeastern Costa Rica are less well resolve...

Genetic Variation of Cytochrome b Gene in Three Local Goat Breeds in Central Java of Indonesia

This study was conducted to elucidate the genetic diversity and phylogenic relationship of three local goat breeds in Central Java of Indonesia based on the cytochrome b (cyt b) gene sequence. Blood samples of 19, 15 and 12 heads of Kacang, Kejobong and Ettawa Grade breeds, respectively, were used as materials of the study. The multiple alignment of cyt b gene was conducted by comparing under s...
