Investigation on Seismic Behavior of Historical Tokatlı Bridge under Near-Fault Earthquakes

open access: yesAdvances in Civil Engineering, 2021
The main purpose of this study is to compare the static and dynamic behavior of a historical single-span masonry arch bridge under different near-fault earthquakes. The historical Tokatlı Bridge, built in Karabük, is chosen for this study. To investigate

Parameterization of historical earthquakes in Switzerland [PDF]

open access: yesJournal of Seismology, 2011
Macroseismic earthquake parameters of historical events have been reassessed in the framework of the update of the Earthquake Catalogue of Switzerland ECOS-09. The Bakun and Wentworth method (Bakun and Wentworth 1997) has been used to assess location, magnitude, and, when possible, focal depth. We apply a two-step procedure.

State-of-the-art of the historical seismology in Colombia

open access: yesAnnals of Geophysics, 2004
In Colombia are available a discreet number of historical seismology investigations, dating back 50 years. This paper reviews basic information about earthquakes studies in Colombia, such as primary sources, compilation of descriptive catalogues and ...

Historical earthquake investigation and research in China

open access: yesAnnals of Geophysics, 2004
China is one of the countries with the longest tradition of culture and has suffered many earthquake disasters, so many earthquake documents have therefore been conserved.

Earthquakes in India and the Himalaya: tectonics, geodesy and history

open access: yesAnnals of Geophysics, 2004
The record of earthquakes in India is patchy prior to 1800 and its improvement is much impeded by its dispersal in a dozen local languages, and several colonial archives. Although geological studies will necessarily complement the historical record, only

A large unknown historical earthquake in the Abruzzi region (Central Italy): combination of geological and historical data

open access: yesAnnals of Geophysics, 1995
The combination of paleoseismological and historical investigation can be used to obtain a complete knowledge of past earthquakes. In Italy the 1000 year-long record of historical earthquakes provides an opportunity to compare data from the catalogue ...

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]

open access: yes, 2004
Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

The Relationship of Small Earthquakes to Strain Accumulation Along Major Faults in Southern California [PDF]

open access: yes, 1983
Fault-plane solutions for recent small (ML ≤ 4.6) earthquakes in the central Transverse Ranges, California, were determined using an azimuthally-varying crustal model.

Anticipating the successor to Mexico's largest historical earthquake [PDF]

open access: yesEos, Transactions American Geophysical Union, 1995
Note in proof: On October 9, as this article was being prepared for publication, a magnitude 7.6 earthquake occurred beneath the Jalisco region and caused significant loss of life and property. This earthquake highlights the societal need for accurate measurements of crustal strain rates in earthquake‐prone zones.

Historical seismograms and earthquakes of the world

open access: yesChoice Reviews Online, 1988
From the standpoint of the seismologist studying actual waveforms (as opposed to travel times) a new era began in 1963 with the establishment of the World‐Wide Standardized Seismograph Network (WWSSN): Well‐calibrated seismograms from all over the world were available from a single data distributor.
