Results of the present study are in good agreement with the PGA calculated from isoseismal map of the Killari earthquake, M w =6.4 (1993). In this paper, a new probabilistic seismic hazard assessment (PSHA) is presented for Peninsular India. ... and recorded PGA data of the Indo-Burma earthquake. Even all three have different pulse shapes of acceleration vs time diagram. analysis and Bhuj earthquake time history and Koyna earthquake time history have been used.

THE Koyna earthquake of December 11, 1967, killed about 200 people and injured a few thousand. Warna reservoir located 20 km south of Koyna began to be filled in 1986. The 1967 Koynanagar earthquake occurred near Koynanagar town in Maharashtra, India on 11 December local time. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. STRUCTURAL PERFORMANCE DURING EARTHQUAKES 2.1 INTRODUCTION Earthquakes are natural hazards under which disasters are mainly caused by dam-age to or collapse of buildings and other man-made structures. Thus, this method can be viewed as a simplified method to evaluate the PGA values at any site in the study area.

The development of a grid model based on a non-parameterized recurrence model using an adaptation of the Kernel-based method that has not … Bhuj, Koyna and El-centro earthquakes (Fig:3, Table:4)are almost having similar magnitude (Range 6.5 to 7.7), but all three have different duration, different PGA value at different peak times. where Y = PGA, y 0 = target PGA, m = magnitude, r = fault-to-site distance (~200 km radius), α = seismicity rate (0.01 for >M5.5 and 0.0025 for > M6.5), Ei (Y > y 0) = annual probability of being exceeded for target PGA levels. The Koyna-Warna region is experiencing a burst of seismicity since August 1993. The Koyna Dam is one of the largest dams in Maharashtra, India.It is a rubble-concrete dam constructed on Koyna River which rises in Mahabaleshwar, a hillstation in Sahyadri ranges. 13th World Conference on Earthquake Engineering Vancouver, B.C., Canada August 1-6, 2004 Paper No. It occurred near the site of Koyna dam, raising questions about induced seismicity, and claimed at least 177 lives and injured over 2,200. Seismic hazard assessment of Koyna region, Peninsular India: using geospatial approach S. M. S. P. Dev* and R. Nagarajan Abstract Background: Earthquake-prone regions from the stable continental regions (like Peninsular India) warrant total seismic hazard estimation from possible sources — reservoir induced or tectonic. This paper highlights the effects on floor which has different loads (mass irregularity) in multistoried building with time history analysis by ETABS software. Keywords—Time History Analysis, Seismic zone, Multistory The world’s largest reservoir induced earthquake of magnitude 6.3 occurred in the Koyna region on December 10, 1967. Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. Experience has shown that for new constructions, estab-lishing earthquake resistant regulations and their implementation is the critical It is located in Koyna Nagar, Satara district, nestled in the Western Ghats on the state highway between Chiplun and Karad The PSHA has been performed using three different recurrence models: a classical seismic zonation model, a fault model, and a grid model. Disaster Management Authority (NDMA 2010), in terms of PGA and pseudo spectral accelerations (PSAs) at T = 0.2, 0.5, 1.0 and 1.25s for 475- and 2475-yr return periods.
The eipcentre was within 5 km of the Koyna Dam (17° 23′ N., 73° 45′ E.). International Refereed Journal of Engineering and Science (IRJES) ISSN (Online) 2319-183X, (Print) 2319-1821 Volume 3, Issue 11 (November 2014), PP.59-67

Review on Variation of Seismic Hazard Parameters at Different Places of India 2 ... 6.5) Koyna earthquake could be related to this tectonic feature (Krishna Brahmam and Negi, 1973).

3.7 magnitude earthquake 2005-11-13 03:56:08 UTC at 03:56 November 13, 2005 UTC Location: Epicenter at 17.287, 74.035 15.2 km from Karād (9.2 miles)
The peak ground acceleration (PGA) at surface level was calculated for the entire South India for four different site classes. The 1970 version (same as Figure 12) of code upgraded the area around Koyna to zone IV. The current Indian seismic zone map (Figure 13) places this area in zone III. Earthquake shaking generally occurs in all three directions. The Killari (Latur) earthquake of 1993 occurred in zone I. The magnitude 6.6 shock hit with a maximum Mercalli intensity of VIII.
