What the record says

NCEI’s account, from the sources it cites.

April 23, 1860. On the 21st, about 2:00 [local time] in Peru (Lima, Callao and other points) the first of a large series of shocks took place. A severe earthquake occurred on the 22nd at 13:50 [local time]. It caused great destruction at Callao, but the sea apparently remained calm [the only report possibly contradicting this is that of April 22, 1859.] On the 23rd, in the morning, about 7:00 [local time], at Lima and Callao, there was a prolonged and severe earthquake of approximately the same strength as the shock of the 22nd... At Callao, after 11:00, the sea withdrew a little from shore, then, changing direction, it barely flooded the shore. These oscillations in level caused general panic in the city. Oscillations in sea level were not observed during the numerous subsequent shocks at Callao.

1859, (possibly 1860) April 22, about 14:00 (local time). A resident of Callao Reads, who was engaged in the observation of phenomenal occurrences and kept a homemade seismometer at home, noted that during the morning of the same [perhaps the following?] day "the sea began to rise". [Most likely, the report refers to the earthquake of April 22 and 23, 1960.]

The previous is from reference #415.
