Abstract

We present the information available on the phenomenon of soil liquefaction in Peru due to the seismic action and its representation in a map of soil liquefaction areas. The map of soil liquefaction areas is drawn to the scale 1: 5'000,000 and presents distinctions between liquefaction and probable liquefaction cases, according to the interpretation of the information available in the literature. All the documentation that presents evidence of the phenomenon of liquefaction, such as the formation of small volcanoes of mud and sand, the violent expulsion of water from the soil, the presence of intense cracking and the differential settlements due to the seismic action, has been detailed in this article.

Highlights

Soil liquefaction has been one of the main culprits of the damage caused to various infrastructure during earthquakes, damage which ranges from small sand volcanoes to massive landslides
The information presented describes the results of extensive research, concluding that the soil liquefaction phenomenon occurs along the coast, in the mountains and in the jungle areas of Peru, with greater incidence along the coast and on sandy soils
A review of the literature indicates that the soil liquefaction phenomenon has occurred in the coastal, mountainous and jungle areas of Peru

Summary

Introduction

Soil liquefaction has been one of the main culprits of the damage caused to various infrastructure during earthquakes, damage which ranges from small sand volcanoes to massive landslides. Peru is located in a highly seismically active region due to the interaction of the tectonic plates of Nazca and South America, as well as by the activity of surface geological faults. These seismic events have led to considerable and continuous human and material losses throughout the Peruvian territory. There are soil liquefaction research and evaluations taking place in some areas of the country carried out by researchers and specialists, [5], [6], [7], [8] and [9]
