Data for article "Rheologic controls on the depth-dependence of megathrust earthquakes"

The files contained in this folder either contain the data used in the manuscript "Rheologic controls on the depth-dependence of megathrust earthquakes" by French et al. or contain the code required to produce the figures.

1. Earthquakes folder contains up to 3 files per margin. One file contains all earthquakes downloaded from CMT near the transect studies, the other two which contain '7km_projected' or '12km_projected' in the name contain the earthquakes projected from within 75 km horizontal distance of the transect and then filter for those within 7 or 12 km normal to the slab top.

2. Temperature Profile files contain two columns: Temperature in C calculated using the England and May (2021) solution and input parameters stated in the manuscript and Depth in km.

3. Slab Profiles Contain the xz coordinates of each slab which were needed to calculate the temperature profiles.

4. Strength Profile Inputs contains the files needed to run the code to create strength profiles (StrengthProfileCalculations.m). These files contain depth (km) and temperature (K) directly from the thermal model outputs, overburden (bars), water pressure (bars) which is used to calcite the specific water volume (cc/mol) and water fugacity (bars). Specific water volume and fugacity are needed for dissolution precipitation creep calculations of the metasediments.

5. StrengthProfileCalculations.m can be used to calculate all strength profiles in the manuscript if the first 6 variables are adjusted to the appropriate values and in file read (M) is selected for the appropriate margin the Strength Profile Inputs folder.

本文件夹内所包含的文件，要么为French等人发表的论文《Rheologic controls on the depth-dependence of megathrust earthquakes》中使用的实验数据，要么为用于生成该论文配图的代码。
1. 地震数据集文件夹：每个俯冲带边缘最多包含3个文件。其中一个文件存储了从剖面研究区域附近的CMT（Centroid Moment Tensor，质心矩张量）目录下载的全部地震事件；另外两个文件名包含“7km_projected”或“12km_projected”字样，它们存储的是经如下处理得到的地震事件：首先提取剖面研究区域水平距离75 km范围内的地震事件，再筛选出距离俯冲板片顶面法向距离在7 km或12 km以内的事件。
2. 温度剖面文件：该类文件包含两列数据，其一为依据论文中给出的输入参数，采用England与May（2021）的解法计算得到的摄氏温度（℃），其二为深度（单位：km）。
3. 板片剖面文件：存储用于计算温度剖面的各俯冲板片的xz平面坐标数据。
4. 强度剖面输入文件：包含用于运行生成强度剖面的代码（StrengthProfileCalculations.m）所需的全部文件。这类文件包含直接来自热模型输出的深度（km）、温度（K）、上覆岩层压力（单位：巴）以及水压力（单位：巴）；其中水压力用于计算比水体积（cc/mol，立方厘米/摩尔）与水逸度（单位：巴），而比水体积与水逸度是变质沉积岩溶解-沉淀蠕变计算所需的关键参数。
5. 若将StrengthProfileCalculations.m中的前6个变量调整为对应数值，并在读取强度剖面输入文件夹中的文件时为目标俯冲带边缘选择“(M)”选项，则可通过运行该代码计算得到论文中所有的强度剖面。
