10/29/1746 | 1746 Lima Callao Earthquake

Description

The 1746 Lima-Callao earthquake has already been studied in detail in various publications. The magnite was initially estimated in a range between 8 and 9.2, but later publications narrowed it to around 8.8 - 9.0.
Recent studies like Jimenez et al. (2013) or Pulido et al. (2012) took out numerical simulations of the tsunami and provided potential rupture models.
Following the historic reports which were summarized by Jimenez et al. (2013), the earthquake was devastating with intensities of X - XI (MMI). Reports also note that the peninsula of Callao experienced up to 10m run-up and the tsunami waves arrived about 30min after the earthquake was felt. The maximum run-up was about 24m along the cliffs of Costa Verde. Waves reached up to 4km in land.
In addition, the were reports of permanent subsidence of Callao.
