Earthquakes constitute the natural hazard that is one of the main natural threats to the northern part of Algeria because of its geographical setting at the Eurasia–Africa plate boundary. Several active multi-segment reverse faults have been identified near urban areas that may rupture during...

The Himalayan fold-thrust belt has been visited by many disastrous earthquakes (magnitude  6) time and again. This active collisional orogen bordering Indian subcontinent in the north remains a potential seismic threat of similar magnitude in the adjoining countries like India, Pakistan,...

Field observations and analog models show that cross-basin faults play a key role in the evolution of pull-apart basins and dominate the distribution of earthquake rupture in basin areas. We studied the long-term history of large earthquakes on a cross-basin fault to reveal its behavior in...

In intra-plate regions with low-seismic activity, seismic cycles last between 10<Superscript>3</Superscript> and 10<Superscript>5</Superscript> years and, consequently, quiescent faults may be capable of producing catastrophic earthquakes. Paleoseismic studies, which are necessary to define capable faults in these regions and to establish their...</superscript></superscript>

Patagonia, including the island of Tierra del Fuego, lies in southernmost South America at the junction of the South American, Antarctic, and Scotia tectonic plates. Historical and instrumental records have documented several local earthquakes of damaging magnitude, posing a threat to the...

Northern Thessaly may represent an important seismic gap within the broader Aegean Region, with major faults bordering the ESE–WNW trending Late Pleistocene–Holocene Tyrnavos Basin. In order to obtain information about the characteristics of past earthquakes and improve our knowledge on the...

On July 28, 2004, the coastal plain of Cirò (Calabria, Ionian Sea) was interested by the sudden opening of a ~5-km-long fracture, paralleling the coastline. All the buildings, roads, and pipelines crossed by the fracture were damaged, inducing several inhabitants to abandon their houses. The...

Quaternary tectonics and paleoseismologicalinvestigations have defined a reliable framework ofactive faults in the southern Umbria and AbruzziApennines. Two sets of NW–SE to NNW–SSE trending, 16to 33 km-long, normal and normal-oblique faults orfault systems have caused the displacement of...

Seismic hazard studies were conducted for Gaziantep city in the South Anatolia of Turkey. For this purpose, a new attenuation relationship was developed using the data of Zaré and Bard and accelerations were predicted employing this new equation. Deterministic approach, total probability...

This study provides a procedure for assessing seismic hazardand uncertainties in regions that are characterised by a large non-instrumental earthquakedatabase and a seismic and tectonic behaviour which doesn't allow an evident seismic zonation.This procedure is a synthesis of the non-zoning or...
