Abstract Site characterization is one of the most important components in seismic hazard analysis because it accounts for effects near‐surface geology on ground motion. It usually quantified based time‐averaged S‐wave velocity (VS) top 30 m profile (VS30). In this study, we estimate site class Jakarta VS structure estimated using microtremor array observations. The results show that microtremor‐derived profiles agree well with standard penetration test‐derived at nine sites. site‐class...

Increasing agricultural production is a top priority in development. There are many problems to be managed. One way increase rice pay attention irrigation conditions. In addition irrigation, rising temperatures also affect the process of flowering and grain filling. At high temperatures, because will calcify, resulting decrease quantity mass. Temperature spikes can reduce viability size seeds when they reach ripe stage. Apart from water air, farmers need soil pH humidity. Many do not yet...

Jakarta  is located on  a  thick sedimentary  layer that  potentially has a very  high  seismic  wave  amplification.  However,  the  available information concerning subsurface model and bedrock depth  insufficient  for seismic hazard  analysis.  In  this  study,  microtremor  array  method  was  applied  to estimate the geometry S-wave velocity of sedimentary layer.

Abstract Typical seismic hazard problem lies on determination of ground motion characteristics associated with future earthquakes. Strong such as Peak Ground Acceleration (PGA) is important information for engineers in order to provide earthquake resistant building. The Indonesian government has provided update maps PGA by released a series official PSHA (Probabilistic Seismic Hazard Assessment) 1978, 2002, 2010 and 2017. On the other hand, NDSHA (Neo-Deterministic method been developed...

The bedrock depth is one of the most important parameters in seismic hazard analysis. This parameter has not been identified well Jakarta. study was conducted to determine Jakarta based on S-wave velocity parameters. Microtremors array method applied this obtain 1D and 2D profiles. spatial autocorrelation (SPAC) used estimate dispersion curves, while structure derived by genetic algorithm. Reffering geological condition area, microtremors measurements were for two East-West lines northern...
