The first stage of the Korean Earthquake Early Warning System (KEEWS) began operations at the Korea Meteorological Administration in January 2015. The goal at this stage is to issue a warning within 50 s of detecting an earthquake of magnitude 5.0 or

The purpose of most earthquake early warning systems (EEWSs) is promptly to identify damaging earthquakes occurring at local distances from a seismic station or network. However, mislocation of a large regional or teleseismic event that is relatively

Fault plane solutions in North Korea and the northern part of the Yellow Sea (37.5oN-40.5oN, 124.5oE-128.5oE) was studied for the earthquakes that occurred from November, 2008 to May, 2013. The analysis was based on the data collected from seismic ne

Earthquake-induced hazards are profoundly affected by site effects related to the amplification of ground motions, which are strongly influenced by local geologic conditions such as soil thickness or bedrock depth and soil stiffness. In this study, a

The scaling relationships of the peak displacement, Pd, and the maximum predominant period, τpmax, of P waves were investigated to estimate magnitudes for earthquake early warning in South Korea. Pd and τpmax were measured for 504 vertical records

Ground‐motion prediction equations (GMPEs) play a crucial role for estimating the seismic hazard in any region using either a deterministic or a probabilistic approach. Indeed, they represent a reliable and fast tool to predict strong ground motion

Many distinct lineaments have been recognized by Landsat images in Korean Peninsula. The Yangsan fault system situated in the southeastern part of Korea is especially linear, continuously traceable for a long distance (about 200km), and particularly

Vertically propagating shear waves reflected from a thin reservoir permeated by a single oriented system of open vertical fractures contain information about the fracture density. The outer perimeter of the hodogram constructed from shear waves polar
