oint Inversion of the 3D P Wave Velocity Structure of the Crust and Upper Mantle under the Southeastern Margin of the Tibetan Plateau Using Regional Earthquake and Teleseismic Data
3D P-wave velocity structure China seismic array detection Panxi region Chuan-Dian Block Daliangshan Block southeastern margin of Qinghai–Tibet Plateau
2018/4/10
The special seismic tectonic environment and frequent seismicity in the southeastern margin of the Qinghai–Tibet Plateau show that this area is an ideal location to study the present tectonic movement...
A new geomagnetic observatory at Livingston Island (South Shetland Islands): Implications for future regional magnetic surveys
Geomagnetic observatories magnetic surveys magnetic anomalies
2015/10/8
A pennanent geomagnetic observatory is always the ideal reference station for monitoring geomagnetic activity during airborne, marine or ground magnetic surveying, especially in Antarctica, where logi...
On the validity of the regional time and magnitude predictable model in China
time dependent seismicity validation test China
2015/9/30
A simplified form of the "regional time and magnitude predictable model" gives the time interval, T, between two successive mainshocks in a region and the magnitude, Mf, of the following mainshock by ...
Compilation of the GSHAP regional seismic hazard for Europe, Africa and the Middle East
Seismic hazard assessment Europe earthquake UN/IDNDR Africa Middle East
2015/9/30
The seismic hazard map of the larger Europe-Africa-Middle East region has been generated as part of the global GSHAP hazard map. The hazard, expressing Peak Ground Acceleration (PGA) expected at 10% p...
The analysis of the Standardized Precipitation Index in the Mediterranean area:regional patterns
Rainfall observatory drought climate variability
2015/9/28
In the present paper we propose a method to assess regional drought by using rain-gauge observations. In particular, we analyse the rainfall on the Marche region. We diagnose drought by means of the S...
Evaluation of the seismic hazard parameters for selected regions of the world:the maximum regional magnitude
maximum regional magnitude activity rate seismic hazard parameters seismic hazard level k-index circum-pacific belt
2015/9/28
Parameters of seismic hazard are estimated by the application of the maximum likelihood method. The technique is based on a procedure which utilizes data of different quality, e.g., the ones where the...
2001 Bhuj-Kachchh earthquake:surface faulting and its relation with neotectonics and regional structures,Gujarat,Western India
surface rupture Kachchh earthquake thrust fault
2015/9/16
Primary and secondary surface deformation related to the 2001 Bhuj-Kachchh earthquake suggests that thrusting movement took place along an E-W fault near the western extension of the South Wagad Fault...
An attenuation study in Southern Italy using local and regional earthquakes recorded by seismic network of Basilicata
seismic attenuation Southern Italy Q
2015/9/15
We determined a set of empirical functions that describe the spectral amplitude decay of S-waves with distance in Southern Italy. We analyzed 32 earthquakes with magnitudes ML 2.0-5.4 and hypocentral ...
Raised marine terraces in the Northern Calabrian Arc (Southern Italy): a ~ 600 kyr-long geological record of regional uplift
Calabrian Arc marine terrace uplift Pleistocene active fault
2015/9/15
The Sibari Plain in the Northeastern Calabrian Arc displays a well-developed suite of marine terraces. This paper
deals with i) the identification and correlation of the terraces; ii) their age assig...
Non-permanent GPS data for regional-scale kinematics: reliable deformation rate before the 6 April, 2009, earthquake in the L'Aquila area
GPS Non-permanent station Subsampling Velocity Strain field
2015/8/28
A GPS-based geodetic study at a regional scale requires the availability of a dense network that is characterized by 10 km to 30 km spacing, typically followed in a few continuous GPS stations (CGPSs)...
Quick regional centroid moment tensor solutions for the Emilia 2012 (northern Italy) seismic sequence
