The magnitude of 8.2 Mfa is not cited to a reliable source. The NOAA article that's linked says 8.2 Ms, but it shows a different time for the earthquake, so there is some discrepancy between this article and the sources. — howcheng { chat} 08:24, 19 February 2018 (UTC) reply

I've changed it to Ms and adjusted the citations. I added the Mfa back in 2010, so I can only imagine that the NOAA page has been updated since then (or I screwed up originally). The timing is a puzzle - the quote from the CERESIS catalogue on the NOAA page gives 15:30 UTC, which is what I used, but I've no idea where the 16:22 from the top of that same page came from as it's not supported by one of the quoted sources - it's difficult when sources are themselves inconsistent.

I checked the Utsu Catalog of Damaging Earthquakes in the World [1], and this also gives 15:30 UTC. It is of course possible that nobody knows exactly the timeshift between the local time in Chile in 1835 and GMT, as it was then. I guess that CERESIS assumes a 4-hour difference as is the case now.

True, Universal Time wasn't adopted until 1884. Thanks for the fixes. — howcheng { chat} 18:44, 19 February 2018 (UTC) reply
