Bathymetry data (ETOPO1) from the National Geophysical Data Center (NGDC) was available for the whole WNAT study region. The ETOPO1 1 arcminute (2.5 km) bathymetric dataset is a global relief model of Earth's surface that integrates land topography and ocean bathymetry (Amante and Eakins, 2009). NOAA's VDATUM (Parker et al., 2003) was used to convert the bathymetry data to the common vertical datum NAVD88.

The bathymetry data was downloaded from NOAA website. The ETOPO1 Relief model is used, which is a 1 arc-minute global relief model of Earth's surface that integrates land topography and ocean bathymetry (i.e. about 1.36km grid). Figure 10 shows a bathymetry and topography used in the present study. Three focal source models have been adopted: USGS model by Hayes (2011), CAS model by the Institute of Geology and Geophysics, Chinese Academy of Sciences (CAS) and the Tsukuba University (TU) model by Yagi and Fukahata (2011). The slip distributions for these 3 models are shown in Figure 11. The rupture surfaces A are 625km×260km,525km×165km, and 525km×200km for USGS, CAS and TU models respectively. The dip angles of the faults are assumed as 10∘,11.7∘ and 12∘ for the USGS, CAS and TU models respectively.
The potential impact of climate change on the seasonality of Phlebotomus neglectus, the vector of visceral leishmaniasis in the East Mediterranean region
Published in International Journal of Environmental Health Research, 2021
The base topographical model was the ETOPO1 Global Relief Model. It is a 1 arc-minute global relief model of Earth’s surface that integrates land topography and ocean bathymetry (Amante and Eakin 2009). The models were created and visualized by QGIS 3.2.3 geographic information system using Grass 7.4.1 of Open Source Geospatial Foundation Project (QGis project 2019).
