Earthquake cycle seismic hazard models for the Eastern Betic Shear Zone

(!) This new version fixes a small error in the hazard calculation coordinates for the sites.

This repository contains the seismic hazard models from the manuscript submitted for publication to NHESS: Consistency of seismic hazard estimates from a physics-based earthquake simulator: a case study in south-eastern Spain.

The "ebsz_hz_models.zip" file contains all hazard models computed in the study. Each hazard model is stored in a separate directory, containing input files for OpenQuake calculations and output files (hazard results).

Models 1 to 3 contain the hazard models from RSQSim simulated catalogues cat-21 and cat-18, and an area source model. These models calculate seismic hazard at 10 sites across the Eastern Betic Shear Zone (EBSZ) with site-specific Vs30 values. The simulated ruptures from cat-21 and cat-18 considered for the hazard models are from Mw 5.5 and above.

Models 4 to 6 contain hazard models from RSQSim simulated catalogues cat-21 and cat-18, and an area source model. These models calculate regional seismic hazard maps across the EBSZ with a constant Vs30 value. The simulated ruptures from cat-21 and cat-18 considered for the hazard models are from Mw 5.5 and above.

Models 7 to 9 are equivalent to models 1 to 3, but with a different magnitude threshold for simulated rupture consideration. In this case simulated ruptures are considered for Mw 5 and above.

Hazard results correspond to site-hazard curves and maps for both PGA and PGV, which are stored within the respective ./results directory of each hazard model directory.

In this repository, we also provide two gifs with the simulated rupture sets of Mw 5.5 and above from cat-21 and cat-18. These ruptures are those used to build the main simulation-based hazard models shown in the manuscript.

(!) 本新版本修正了场地地震危险性计算坐标中的一处细微误差。

本仓库包含提交至NHESS（Natural Hazards and Earth System Sciences，自然灾害与地球系统科学）期刊待发表的论文《基于物理的地震模拟器的地震危险性估计一致性：以西班牙东南部为例》中的地震危险性模型。

"ebsz_hz_models.zip"文件包含本研究中所有计算得到的危险性模型。每个危险性模型均存储于独立目录中，内含用于OpenQuake计算的输入文件与危险性结果输出文件。

模型1至3包含源自RSQSim模拟目录cat-21、cat-18的危险性模型，以及一个面源模型。此类模型针对东贝蒂克剪切带（EBSZ, Eastern Betic Shear Zone）的10个场地开展地震危险性计算，各场地均配有专属的Vs30（场地平均剪切波速）值。本研究中用于构建该类危险性模型的cat-21与cat-18模拟破裂事件，均为震级Mw≥5.5的地震。

模型4至6同样包含源自RSQSim模拟目录cat-21、cat-18的危险性模型，以及一个面源模型。此类模型针对EBSZ区域生成全域地震危险性分布图，采用统一的Vs30值。所用的模拟破裂事件同样限定为Mw≥5.5的地震。

模型7至9与模型1至3等效，但模拟破裂事件的震级阈值有所不同：本次采用的震级阈值为Mw≥5。

危险性结果包含PGA（峰值地面加速度）与PGV（峰值地面速度）对应的场地危险性曲线及分布图，存储于每个危险性模型目录下的./results子目录中。

本仓库同时提供两段GIF动图，分别展示cat-21与cat-18中Mw≥5.5的模拟破裂集合——这些破裂事件正是构建论文中核心基于模拟的危险性模型所用的数据源。
