THE ACCELERATION RESPONSE SPECTRUM AND EFFECTIVE DURATION OF LEBAK EARTHQUAKE JANUARY 23, 2018 IN JAKARTA REGION

open access: yesSpektra: Jurnal Fisika dan Aplikasinya, 2019
Jakarta is the capital city of Indonesia with a very high population density low to the upper distribution of buildings which causes many areas of Jakarta to have a high vulnerability to natural disasters, one of which is an earthquake.

Response Spectrum for Green Light-Induced Acceleration of Heading in Wheat cv. Norin 61

open access: yesPlant Production Science, 2009
The response spectrum for green light induced-acceleration of heading in wheat cv. Norin 61 was investigated using narrow-bandwidth (10 nm) green light within the range of 520–550 nm. Heading was observed from approximately 30 days after emergence.

Study on the influence of the seafloor soft soil layer on seismic ground motion [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2021
In the complex medium system of the sea area, the overlying seawater and the surface soft soil have a significant impact on the seafloor ground motion, which brings great seismic risk to the safety of offshore-engineering structures.

A Semi-Analytic Method to Estimate the Response Spectrum of the Synthetic Acceleration Records with Evolutionary Spectrum [PDF]

open access: yesScientia Iranica, 2021
In this paper, we introduce a semi-analytic procedure for deriving the response spectrum of the synthetic acceleration records generated using the Double Frequency Model (DFM). DFM is a filtered white noise method for fully non-stationarity synthetic acceleration records.

A Centrifuge Model Test of the Ground Motion Response in a Moderately Stiff Soil

open access: yesShock and Vibration, 2021
The ground motion response in a moderately stiff soil in seismic events has been traditionally studied based on the actual field records which, however, have yet to offer consistent results regarding the amplification effect of the ground motion.
