Abstract

The article generalizes materials on the earthquake of March 31, 1761, which is almost unknown in our scientific discourse, although very significant in its seismological impacts; it can therefore be considered as a twin of the Great Lisbon disaster of November 1, 1755. The 1761 earthquake struck a large part of Europe and, although it did not involve such disastrous consequences as the 1755 Lisbon quake, it significantly changed the seismic regime observed after after the latter. Both earthquakes were followed by tsunamis on the western margins of Europe and the eastern coasts of North America; they also triggered seismic activations of vast, spatially different regions in Western Europe and North Africa. It is possible to associate a number of strongest seismic events in the West Atlantic region with the 1761 earthquake. In the recent research literature on the topic, predominantly by Portuguese authors, the sources of both earthquakes are located in the eastern part of the Azores–Gibraltar Transform Fault. It is of particular interest that the initial data for this article were taken from the newspaper Sankt-Petersburgskie vedomosti for the 18th century and were supplemented with information from historical catalogs and recent foreign papers.

里斯本大地震的孪生兄弟（根据18世纪Sankt-Peterburgskie vedomosti报纸的资料）

摘要

本文概括了关于1761年3月31日地震的资料，尽管它在地震学方面的影响非常重大，但在我们的科学论述中几乎是未知的。因此，它可以看作是1755年11月1日大里斯本灾难的孪生兄弟。1761年地震袭击了欧洲大部分地区，尽管它没有像1755年里斯本地震那样造成灾难性的后果，但它极大地改变了地震体制在后者之后观察。两次地震之后，在欧洲西部边缘和北美东部海岸发生海啸。他们还引发了西欧和北非广大空间不同地区的地震活动。可以将西大西洋地区许多最强烈的地震事件与1761年地震联系起来。在有关该主题的最新研究文献中（主要由葡萄牙作家撰写），两次地震的来源都位于亚速尔群岛－吉格拉塔尔变换断层的东部。特别有趣的是，本文的原始数据来自报纸Sankt-Petersburgskie veomosti适用于18世纪，并辅以历史目录和最新外国论文中的信息。
