Abstract

This Plenary Lecture summarizes the seismicity of Mars recorded by the NASA InSight mission, which landed on Elysium Planitia on 26 August 2018. Equipped with a highly sensitive seismometer, the lander has been successfully recording the seismicity of Mars for over three years. Different types of marsquakes have been identified, including low-frequency events with mantle-going phases and shallow high-frequency events characterized by crustal propagation. More recently, a few meteoric impacts have also been identified. Over a thousand events have been recorded, with magnitudes reaching up to MW 4.7. Here we review the techniques used by the MarsQuake Service to locate and characterize marsquakes and the active crustal processes in different areas of the red planet, and we discuss the different types of marsquakes.

美国宇航局洞察号观测到的火星地震活动

本次全体讲座总结了2018年8月26日登陆极乐平原的美国宇航局洞察号任务记录的火星地震活动。该着陆器配备了一个高度敏感的地震仪，三年多来一直成功地记录火星的地震活动。已经确定了不同类型的地震，包括具有地幔移动阶段的低频事件和以地壳传播为特征的浅层高频事件。最近，也发现了一些流星撞击。有记录的地震超过1000次，震级最高可达4.7兆瓦。在这里，我们回顾了火星地震服务在火星不同地区用于定位和表征火星地震和地壳活动过程的技术，并讨论了不同类型的火星地震。

期刊介绍： The European Review is a unique interdisciplinary international journal covering a wide range of subjects. It has a strong emphasis on Europe and on economics, history, social science, and general aspects of the sciences. At least two issues each year are devoted mainly or entirely to a single subject and deal in depth with a topic of contemporary importance in Europe; the other issues cover a wide range of subjects but may include a mini-review. Past issues have dealt with: Who owns the Human Genome; From decolonisation to post-colonialism; The future of the welfare state; Democracy in the 21st century; False confessions after repeated interrogation; Living in real and virtual worlds.
