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"（《流变学调控大型逆冲断层地震的深度依赖性》）中使用的研究数据，要么为生成该论文配图所需的代码。 1. 地震文件夹：每个俯冲带陆缘最多包含3个文件。其中一个文件存储了从CMT（矩心矩张量，Centroid Moment Tensor）目录下载的、所有位于剖面研究区域附近的地震事件；另外两个文件名中包含"7km_projected"或"12km_projected"字样，其收录的地震事件为：先筛选出距剖面水平距离在75 km以内的地震，再进行投影处理，最终筛选出垂直于板片顶面距离处于7 km或12 km范围内的事件。 2. 温度剖面文件：包含两列数据，分别为采用England与May（2021）的解法、结合论文中指定的输入参数计算得到的摄氏温度（℃），以及以千米（km）为单位的深度。 3. 板片剖面文件：存储各板片的xz坐标数据，该数据为计算温度剖面所需的基础输入信息。 4. 强度剖面输入文件：包含运行StrengthProfileCalculations.m脚本以生成强度剖面所需的全部文件。这些文件涵盖：直接来自热模型输出的深度（km）与温度（K）、上覆压力（bars），以及用于计算比水体积（cc/mol）与水逸度（bars）的水压（bars）。其中比水体积与水逸度是副变质岩溶解-沉淀蠕变计算的必要参数。 5. 若将StrengthProfileCalculations.m脚本的前6个变量调整为适配研究的参数值，并在读取文件时为对应陆缘选择文件读取模式（M），即可通过该脚本计算出论文中所有的强度剖面。
