An earthquake is a natural catastrophic phenomenon frequent in the Greek territory, which geoscientists are called to address. The challenge of dealing with earthquakes has many components and concerns human life, the built environment, and cultural heritage.

Geology plays a dominant role in understanding earthquakes, and thus the thorough training of geoscientists in Seismology is essential, a field to which the book you hold contributes. Geology as a science can determine the location of an earthquake in the Earth's crust in relation to tectonic plates, the primary and secondary phenomena associated with an earthquake, and the impact of active faults on the Earth's surface.

The aim of geology is to provide answers to questions such as how many earthquakes have occurred in a seismic source (fault), what rate of slip an active fault exhibits, how often strong earthquakes occur, and how much an active fault affects or can affect human activity. Geological research can help in addressing three fundamental questions that represent a primary goal of any earthquake analysis effort. These questions concern: the time, the place of an earthquake's occurrence, and the distribution of its impacts.
