Incorrect 362 date reported in older Scientific literature

Kagan et. al. (2011) dates the two earthquakes to ~362 CE and 363 CE. The 362 CE date is based on Ben-Menahem (1991) who misdated the earthquake to 24 May 362 CE - perhaps partly influenced by Sieberg (1932a) who dated the Cyril Quake(s) to June 362 CE without citing a source. A deep examination of the various textual accounts reveals that mistakes were made by early earthquake cataloguers in parsing the accounts leading to incorrect months and dates and likely years as well. Since these earthquakes appear to be well dated by contemporaneous sources to 363 efforts to unravel the source of this propagating catalogue dating mistake will not be pursued here. Russell (1980, p.52) relates that "the scholarly process by which 362 rather than 363 came to be the accepted date is difficult to ascertain".
