Information background of 11th–15th centuries earthquakes located by the current catalogues in Vrancea (Romania)

Abstract

Earthquake catalogues for Romania supply for 11th–15th century earthquakes located in the region of Vrancea records that consist of a complete set of parameters, including magnitude and depth. Scope of this paper is to verify the reliability and consistency of these parameters with the informative background as explicitly referenced by the catalogues. After retrieving the original sources they mention, the set of data appeared to be related almost exclusively to the Russian plain and too poor to be at the very origin of the parameter assessment. Data for 19th–20th century earthquakes, such as instrumental locations and CMT solutions, added to the understanding of the macroseismic response of the Russian plain to Vrancea earthquakes. On the one hand, the investigation and analysis of historical earthquake records for the fourteen events listed by the catalogues in the 11th–15th centuries has shown that for three earthquakes (1022, 1038, 1258) no primary sources could be traced, and three more earthquakes (1091, 1170 and 1328) are attested only by scarcely reliable records and had to be classified as doubtful, and one (1473) is simply a duplication of the 1471 event. On the other hand, the availability of data on recent earthquakes that may be compared to historical ones in terms of macroseismic effects allowed the authors to agree with the previous catalogue compilers’ solution with regard to both magnitude and depth of the past earthquakes for which do exist reliable primary historical records.

Annex 1: Notes on early Russian chronicles and excerpts

Russian Chronicles are called letopis’, which literally means “annual records”. The original versions of the chronicles survived in several spisok (handwritten copy) of 14th–18th centuries. According to the place of compilation or the place of main interest, these copies are subdivided into razryad (literally: class, category, rank, or sort), as for example, “initial Kiev”, “Novgorod”, “Pskov”, and so on. Copies pertaining to the same razryad (class) have significant differences in style, in what events they report and how they have been interpreted. These characteristics define their izvod (redaction). For example, one chronicle can be classified as the “Chronicle of initial Suzdal izvod” (Lavrentevskiy spisok and similar). The survival of these Chronicles in several copies, in which linguists and historians can identify the differences, led to the widely accepted opinion, that all extant Russian Chronicles are later compilations, the original sources of which did not survive. This opinion is also supported by the fact that earliest known Russian Chronicle is dated to 1377, though the first record in it dates back to 852.

Here follow a few remarks on the Russuna chronicles upon which this paper relies. The relationships among Russian chronicles are given according to (Shchapov 2003).

Lavrentevskiy Chronicle The Chronicle is dated to 1377, and it was copied from an earlier set of sources by the monk Lavrentiy. This gathering work was ordered by Dmitriy Konstantinovich velikiy knyaz (Grand Duke) of Suzdal’—Nizhniy Novgorod princedom. It includes Povest’ Vremennykh Let (PVL), which is the earliest known part of Russian Chronicles (852–1116), to which sections were added, extending it up to 1305. There are some gaps in the Chronicle, and namely for the years 898–922, 1263–1283, and 1288–1294. At the beginning, the Lavrentevskiy Chronicle describes the events in Kievskaya Rus’; later, during the twelfth century it is mostly concentrated on events at Vladimir, while starting from the thirteenth century it includes a wealth of information on the Rostov princedom. The place where monk Lavrentiy wrote the chronicle is not known for sure, either in Vladimir or in Nizhniy Novgorod, in the Pecherskiy Monastery. This chronicle was published in 1846 in the first volume of the PSRL by the Archeographic Commission. In this edition, some gaps were filled using the Radzivilovskiy and Troitskiy chronicles, which are similar to the Lavrentevskiy.

Chronicles of Novgorod There are two redactions (izvod) of the first Novgorod Chronicle, the elder and the younger. The elder redaction exists only in one copy, the Synod spisok, which is kept in the archive of Synod. The beginning of the chronicle is lost; it started with records of events of 1016. The Synod copy is in two parts: the earliest, up to 1234, was compiled in the second half of the thirteenth century; the most recent includes the period 1234–1330, ending with the year when it was copied. After 1330 different handwritings added news on 1331–1333, 1337, 1345 and 1352. These later additions are related to Yurev Monastery in Novgorod.

The younger redaction of first Novgorod Chronicle exists in several copies. How this text took the form it has now in PSRL and in other editions is a rather complicated story, studied and related by Shakhmatov (1914). Its core formed in the first quarter of the fifteenth century, and it extends to 1439 or 1441. It is possible, that from the beginning up to 1015 this copy includes the lost part of elder redaction.

Except for the first Novgorod chronicle in two redactions, there are also the chronicles known as Novgorod II, III, IV, Sofiyskaya letopis’, and Supral’skaya letopis’. All of them mostly report on local events, or events affecting the state of Novgorod. Pan-Russian events were rarely reported in these later Novgorod chronicles and appeared more or less randomly.

Voskresenskaya Chronicle It is a pan-Russian Chronicle of the sixteenth century, which reflects the interests of Grand Dukes of the princedom of Moskva. Thirteen copies are known, and the one belonging to the Voskresensk Monastery in New Jerusalem (near Moskva) gave the name to the Chronicle. It is based on the Moskva code of 1479 as known in a copy made in 1526 and the Tikhonov copy of the Rostov code (1489–1503).

Nikonian Chronicle The core of this chronicle is dated to the thirteenth century and is named after the patriarch Nikon who owned one of the copies. The main part of this chronicle was compiled in 1539–1542. The Nikonian chronicle is a huge compilation based on several sources, from chronicles of places close to Novgorod, Voskresensk, Iosaf (since 1446), to chronological tables, and special accounts of important historical events, and to today-lost local chronicles and oral-tradition stories. The compilers of the Nikonian Chronicle did an extensive editorial work, assembling and rearranging the historical material in their hands in such a form to prove the leading role of the Moskva dukes and the Church in the making of the Russian state. Later on it became the official chronicle recognized by both the ecclesiastic and the civil authorities.

The most extensive publication of the Russian Chronicles is the 30-volume collection made by the Archeographic Commission in 1850–1920. There are some facsimile reprints, the latest of which started being published in 1997 by the Institute of Russian History (IRH) of the Russian Academy of Sciences.

Some chronicles have been translated into English, such as the Novgorod chronicle in the edition by Shakhmatov (1914). Recently, Ostrowski (2004) compiled an interlinear collation (10 lines maximum) of the Povest’ Vremennykh Let (i.e. the earlier part of PSRL up to 1116). In an extensive introduction in both Ukrainian and English, he says: “The present interlinear collation includes the five main manuscript witnesses to the PVL, three published versions of the PVL, the corresponding passages from the published version of the Novgorod I Chronicle, and the corresponding passages from the Trinity Chronicle. It also includes a paradosis, that is, a proposed best reading”–V. 1, p. xix.”

For this investigation, the 1091 and 1107 records were checked in the edition by Ostrowsky (2004), while the records of earthquakes in the time-window 1122–1446 have been checked against the edition supplied by the IRH reprints. The only record falling out of the time-span presented in described above chronicles is the one related to the 1471/1473 event.

A remark on the calendar in use in the Russian chronicles is needed to make explicit how the dates of the earthquakes are given in this paper. From the 11th to the 15th century in the Eastern Orthodox countries, and Russia among them, the calendar of the “Byzantine Era” was officially in use. It established the beginning of the world in the year 5508 B.C., so that the 1 A.D. corresponded to 5509. From 11th up to mid of 15th century, the beginning of the year was set on the 1st of March. This dating is referred in the Russian historical documents as the “March-dating”. Starting from mid fifteenth century the beginning of the year was set on the 1st of September (“ultra-March dating”). The Byzantine calendar was abolished on 1st January 1700, when the Julian calendar was adopted. This means that in converting the dates to the Julian calendar (in use in Russia until 1917) when dealing with events occurred between March and December (when the “March-dating” was in use) or September and December (for the “ultra-March dating”) one year has to be subtracted. With respect to the use in the chronicles described above, the “ultra-March dating” was introduced in the Nikonian chronicle, which means that its compilers made the conversion between the two dating styles as given by the previous chronicles. This was not always done accurately, and created some problems of correct dating.

For the sake of completeness, the excerpts from the chronicles given in the article in English translation are here supplied in modern Russian for the readers who might be interested.
