Risk communication and earthquake psychology: a research on earthquake news
Vivat AcademiaIntroduction: Risk communication is an inseparable part of any immediate reply. Earthquakes are complicated emergencies that exacerbate issues with risk communication and highlight these issues for scientists to communicate about. Turkey is vulnerable to various natural disasters, including earthquakes, floods, landslides, and thunderstorms, due to its

Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Dizhen xuebao针对当前北京地区缺乏适用的覆盖层厚度与场地自振频率经验关系的现状，首先利用广泛收集的北京市地震安全性评价工作中获取的1 142个钻孔数据资料，采用幂函数模型对其进行回归拟合分析，获得了土体剪切波速随深度变化的关系式，然后对该关系式进行推导建立了适合北京地区场地特征的覆盖层厚度与场地自振频率之间的经验关系，藉此为北京市无剪切波速数据的工程场地提供vS20和vS30参考，并对土层剪切波速和覆盖层厚度进行预估。
