The 1999 Izmit earthquake (17/08/1999, Mw=7.4) was one of the largest earthquakes in the past 100 years in the northwestern region of Turkey. This earthquake occurred along the Izmit-Sapanca fault within the Northern Anatolian Fault Zone. Variations in the generalized fractal dimensions (Dq) of clustering in time and space, the Gutenberg-Richter b-value, and earthquake frequency (N) are evaluat...

S U M M A R Y We investigate two great earthquakes that occurred in the Aleutian Islands and Chile, within 30 min of each other, on 1906 August 17, based on a collection of seismograms compiled shortly after the events by scientists at Strasbourg. The method of Preliminary Determination of Focal Mechanisms (PDFM) is applied to 14 mantle waves from seven stations, in order to resolve the moment ...

The February 21, 2008, Wells earthquake (MW=6.0) occurred in a region of northeastern Nevada where the seismicity has historically been low relative to western Nevada. In a region of area of approximately10 5 km 2 of northeastern Nevada, based rates of smaller earthquakes in the region prior to 2008, earthquakes of MW=6.0 or larger are expected with a rate of about 0.01 per year. The probabilit...

Rapid procedures (i.e. within 5 to 15 minutes) for earthquake and tsunami early warnings focus on earthquake location, depth, magnitude, and slowness, but initial tsunami early warnings are more often issued without knowing the mechanism of the earthquake. Kawakatsu (1998) proposed using a limited number of stations to automatically detect, locate and determine the source parameters of earthqua...

TheM7.6 Nicoya earthquake struck at the interface between the Cocos plate and the Caribbean plate on 5 September 2012 inducing a ground acceleration of 0.5 m s−2 at the Irazú-Turrialba volcanic complex. We use data from six seismic stations deployed around and atop the Irazú-Turrialba volcanic complex to show the increase of local seismic activity after the M7.6 Nicoya earthquake. The response ...

Immediately following the 1966 Parkfield earthquake a continuing program of fault displacement measurements was undertaken, and several types of instruments were installed in the fault zone to monitor ground motion. In the year subsequent to the earthquake a maximum of at least 20 cm of displacement occurred on a 30 km section of the San Andreas fault, which far exceeded the surfidal displaceme...

The Bam Earthquake caused one of the most destructive disasters from naturally occurring hazards in recent years. Children are one of the most vulnerable age groups during disasters, in terms of both physical and psychological injuries. The assessment of pedatric injuries in the aftermath of the Bam Earthquake is discussed is this article. Within one week of the Earthquake, 119 patients < 16 ye...

A class of probability models for earthquake occurrences, called shortterm exciting, long-term correcting (SELC) models, is presented. This class encompasses features of two different classes of models presently used in hazard analysis to characterize earthquake catalogs: (1) self-exciting models and (2) self-correcting models. It offers the potential for a unified approach to the analysis and ...

OBJECTIVES This article sought to review and compare data of major earthquakes of the past decade and their aftermath in order to compare the magnitude, death toll, type of injuries, management procedures, extent of destruction and effectiveness of relief efforts. MATERIALS AND METHODS A retrospective study of the various aspects of management and aftermath of 5 major earthquakes of the past ...
