Abstract In January 1531, the Tagus River Estuary was hit by a strong earthquake, the intensity of which in Lisbon was, according to relevant authors, greater than that of the 1755 earthquake. It was cited by most of the European annalists of the time and was responsible for the destruction of structures, the loss of lives, and enormous panic, thus making it one of the most disastrous earthquakes in the history of Portugal. If we give credit to the detailed descriptions, the maximum intensity was probably X MSK. According to our study, the seismic event was probably caused by the Lower Tagus f

Abstract (sommario):
Earthquakes have and continue to, occur worldwide, though some places are affected more than others by earthquake-induced ground shaking and the same earthquake can cause more damage in one area than in nearby locations due to site-specific geological site conditions, also known as local site effects. Depending on the chronology of the earthquakes, various disciplines of seismology include instrumental and historical seismology, archaeoseismology, palaeoseismology and neotectonics, each focusing on using specific sources of information to evaluate recent or ancient earthquakes.

Abstract (sommario):
Today, many learned builders know that earthquakes in the territory of, for example, a settlement can manifest themselves in the form of the first most powerful earthquake (main underground shock), which is usually followed by a series of weaker repeated earthquakes (repetitive shocks). There are many examples of such a sequence of manifestations of strong earthquakes in a certain territory, when tens of thousands of people die in destroyed buildings during repeated exposure earthquakes. It is thanks to these examples that scientists, builders, understand the main cause of death due to repeate

Abstract (sommario):
Studies on magnetic disturbances in ultralow frequency ranges related to earthquakes observed by satellites are still limited. Based on Swarm satellites, this paper proposes a new analysis method to investigate pre-earthquake magnetic disturbances by excluding some known non-earthquake magnetic effects that are not confined to those caused by intense geomagnetic activity. This method is demonstrated by two earthquake cases. One is an interplate earthquake, and the other is an intraplate earthquake. Magnetic disturbances around these two earthquakes are associated with solar wind and geomagneti

Abstract Earthquake observations contributed by human observers provide an invaluable source of information to investigate both historical and modern earthquakes.

Eyewitness accounts can contribute to modern science only if they are recorded in the first place and archived in an accessible repository. In this study, we explore the extent to

This resonance phenomenon was predictable on the basis of similar experiences in past earthquakes.

Abstract (sommario):
In northern Patagonia, Argentina, we examined the influences of climatic variation and inter-site variation in substrate stability on the dendroecological effects of earthquakes. In association with the great earthquake in 1960 centered off the coast of nearby Valdivia, Chile, extensive tree mortality occurred in northern Patagonia in Nothofagusdombeyi–Austrocedruschilensis stands on unstable debris fans. To examine the effects of the 1960 and earlier earthquakes on tree growth, we developed tree-ring chronologies from samples of the surviving A. chilensis on unstable debris fan sites and at a

The seismic shaking observed around Delhi and the surrounding region due to near-field and far-field earthquakes is a matter of concern for the seismic safety of the national capital of India, as well as the historical monuments of the region. Historical seismicity indicates that the Delhi region has been affected by several damaging earthquakes originating from the Himalayan region as far-field events, as well as due to near-field earthquakes with epicenters close to Delhi. The historical records, along with recent archeoseismological studies, suggest that Qutab Minar, a UNESCO World Heritage

Abstract. There will be a change in the Earth's local sub-surface thermal structure before and/or after an earthquake. In this work we have introduced a new parameter (I) which relates integral effect of temperature variation and seismic activity. This parameter in its various forms integrates the temperature variations during one year before and after earthquake. Some recent earthquakes are chosen throughout Iran on Alps-Himalayas fault zone with magnitudes 4.5 and more. Subsurface temperatures up to one meter depth measured in nearby weather stations are used as there is no deeper data avail

The aim of the research is to assess the maximum possible magnitude of the electric field of a seismogenic nature that penetrated the ionosphere/plasmasphere, which could cause the ionospheric effects observed experimentally.

The content of earthquake catalogs results from piling data of different origin, interpreted according to diverse approaches. Consequently, the homog

The seismic activity in the region was essentially expected after the 2003 Lefkas earthquake and the 2014 Cephalonia earthquakes. Between these earthquake affected areas, the tectonic stresses were not released after the 1948 Lefkas earthquakes. Instead, they were intensifying and accumulating until the generation of the 2015 event. It was felt in Lefkas and the surrounding region a

Dating earthquake geological effects associated with historical earthquakes gives us relevant information for estimating the seismic acceleration value experienced in the ground. Historical manuscripts describing earthquakes and its effects help to assign a seismic intensity about the ground motion. In this context, lichenometry represents a good semi-quantitative method for dating exposed rock surfaces related to earthquake phenomena. In this work, we have carried out a lichenometry analysis for dating a large rockfall located 700 km from the epicentre of the Great Lisbon Earthquake, which oc

Analysis and interpretation of the available historical accounts indicate that the 1836 event occurred east of Monterey Bay, far from the Hayward fault, and was of M ∼ 6¼. Also, the 1838 event was not confined to the 60-km peninsula San Andreas as current models indicate. Instead, faulting probably extended from San Francisco to San Juan Bautis

In this study, the authors first describe ground motions, crustal deformation and surface break observations caused by earthquakes having different faulting mechanism.
