“…This effect can be studied by considering local site effects to understand the seismic response of soil deposits. Local site effect and extensive site characterization are necessary for places where shallow geology is diverse and strong topographic fluctuations prevail (Bonilla et al 1997 ; Nardone and Maresca 2011 ; Singh et al 2017 ; Ferraro et al 2018 ; Putti and Satyam 2018 ; Naik et al 2020 ).…”

The Jammu Region (JR) in the northwestern Himalayas trigged by medium to high magnitude near-field as well as far-field earthquake events, including the most recent 2019 Mirpur earthquake. In this paper, an attempt has been made to develop the zonation map for liquefaction hazard in the JR based on liquefaction potential index ( ) and probability of liquefaction ( ). To achieve this, factor of safety against liquefaction was estimated using standard penetration test (SPT) data collected from geotechnical consultancies and shear wave velocity measured during field testing at 243 locations, and an integrated liquefaction hazard map generated. The liquefaction features such as sand blows and ground rupture were found in Jatah (Samba district) and Simbal (Jammu district). According to the integrated hazard map, places near the bank of Tawi River and Ravi River in Jammu have young alluvium, making them particularly prone to liquefaction. Liquefaction does not occur in the eastern and western sections because of high shear wave velocities and rock at shallow depth, and it also does not occur in the central area due to thick sand deposits. values ranged from 0 to 27.45 having very low to very high liquefaction risk. is greater than 0.75 for sites located on the southwestern side due to uniformly graded soil having extremely low SPT ( N ) and values. This study will aid site planners in the construction of structures that consider liquefaction mitigation and well-defined liquefaction risk measures.

“…However, basic seismic data (such as house damage), which is necessary to estimate the results of the earthquake intensity according to different scales, is difficult to obtain. Earthquake intensity scales are also constantly being developed [79,80]. In the future, regional risks can be further studied according to different earthquake intensity scales to enhance the comparability of research results on a global scale.…”

Earthquakes often cause secondary disasters in mountainous areas, forming the typical earthquake-landslide-debris flow disaster chain for a long time that results in a series of losses. It is important to improve the risk assessment method from the perspective of cascading effect of such a disaster chain, by strengthening quantitative research on hazards of the debris flows which are affected by landslide volume and rainstorm intensity. Taking Wenchuan County as an example, the risk assessment method for population loss of the disaster chain is established and the risks are evaluated in this paper. The results show that the population loss risk is 2.59–2.71 people/km2 under the scenarios of the Wenchuan Ms8.0 earthquake and four rainstorm intensities. The impacts of landslide and debris flow after the earthquake were long-term and profound. A comparison of risks caused by each element of the chain revealed that the risk associated with the earthquake accounted for the highest proportion, and landslide and debris flow accounted for 38.82–37.18% and 3.42–7.50%, respectively. As the earthquake intensity increases, the total risk posed by the disaster chain increases significantly. The risk caused by the earthquake is the highest in high earthquake intensity zones; while in the lower-intensity zones, landslides and debris flows pose relatively high risks. The risk assessment results were verified through comparison with actual data, indicating that the simulation results are quite consistent with the existing disaster information and that the risk assessment method based on the earthquake-landslide-debris flow cascade process is significant for future risk estimation.

“…Nevertheless, the ESI-07 has some problems that remain unsolved to date, which can be overcome with a larger number of case studies from diverse tectonic settings, geological settings, earthquake mechanism, and distribution of EEEs [23,25,[28][29][30]. In this respect, the applicability of the ESI-07 intensity scale has been tested for the most damaging earthquake during the modern seismic era of the Korean Peninsula.…”

The earthquake environmental effects (EEEs) around the epicentral area of the Pohang earthquake (Mw-5.4) that occurred on 15 November 2017 have been collected and classified using the Environmental Seismic Intensity Scale (ESI-07 scale) proposed by the International Union for Quaternary Research (INQUA) focus group. The shallow-focus 15 November Pohang earthquake did not produce any surface rupture, but caused extensive secondary environmental effects and damage to life-line structures. This earthquake was one of the most damaging earthquakes during the instrumental seismic era of the Korean Peninsula. The EEEs included extensive liquefaction, ground cracks, ground settlement, localized rockfall, and variation of the water table. The main objective of this paper was to carry forward a comparative assessment of the Pohang earthquake’s intensity based on traditional macroseismic scales and the ESI-07 scale. With that objective, this study will also make a substantial contribution to any future revision of the ESI-07 scale, which mostly comprises case studies from Europe and South America. The comparison of the ESI-07 scale with traditional intensity scales similar to the intensity scale used by the Korean Meteorological Administration for the epicentral areas showed 1–2-degree differences in intensity. Moreover, the ESI scale provided a clearer picture of the intensity around the epicentral area, which is mostly agricultural land with a lack of urban units or buildings. This study urges the integration of the traditional and ESI-07 scale for such small magnitude earthquakes in the Korean Peninsula as well as around the world in future. This will predict seismic intensity more precisely and hence provide a more-effective seismic hazard estimation, particularly in areas of low seismic activity. The present study will also provide a useful and reliable tool for the seismic hazard assessment of similar earthquakes around the study area and land-use planning at a local scale considering the secondary effects.
