Research Overview

My research focuses on advancing seismic hazard assessment and earthquake magnitude estimation. I have made significant contributions in the following areas:

1.                                    New Earthquake Magnitude Scale: I developed a novel earthquake measuring scale, the Das Magnitude Scale, which surpasses the conventional Moment Magnitude (Mw) scale. The Das Magnitude Scale extends the moment magnitude scale to include lower and intermediate magnitudes, with a particular emphasis on utilizing body waves, especially P waves. By incorporating abundant data from various sources, including the International Seismological Centre (ISC) and Global Centroid Moment Tensor (CMT) databases, this scale provides more accurate magnitude estimates and enhances seismic hazard and risk assessment on a global scale (P#20, 25)

2.                                    Improved General Orthogonal Regression (GOR) Techniques for preparing Earthquake Catalog: I have extensively researched and enhanced the application of General Orthogonal Regression (GOR) in earthquake magnitude conversion. By refining the conventional GOR approach, I developed an improved methodology that considers the true points on the GOR line, resulting in unbiased estimates of conversion magnitudes. This approach offers superior accuracy, lower errors in slope and intercept, improved correlation coefficients, and standard error values compared to standard least-square regression (SLR) and conventional GOR methods. Furthermore, I demonstrated the susceptibility of conventional GOR to error variance ratio, whereas the proposed GOR technique remains robust. These advancements in GOR have significant implications for earthquake magnitude conversion and seismic hazard estimation (P#6, 7, 8, 13, 18)

3.                                    Seismic Hazard Assessment Studies:

Northeast India: For one of the most seismic regions in the world, northeastern India, I conducted comprehensive seismic hazard assessments. I prepared a unified earthquake catalog using my proposed methodology, incorporating geological and tectonic features, focal mechanism solutions, and spatial distribution of earthquake events. By deriving key parameters such as activity rate, seismicity parameter, and maximum magnitude, I determined seismic hazard values for different zones. Additionally, I created zoning maps for peak ground acceleration (PGA) and response spectral amplitudes, enabling accurate hazard computations and facilitating risk assessment in the region. Additionally, I performed Monte Carlo simulations to quantify uncertainty and express the results in terms of mean and Coefficient of Variation (COV). Furthermore, I prepared design spectra for various return periods, contributing to the understanding of seismic hazards in the Himalayan region (P#15).

b. Chilean Seismic Gap:

I present a comprehensive Probabilistic Seismic Hazard Assessment (PSHA) model for Southern Peru and Northern Chile. This seismically active region, situated between 17°S and 30°S, and 67°W and 74°W, has a history of destructive earthquakes and tsunamis. The study focuses on meticulous earthquake catalog quality control and derives regional magnitude scale correlations. PSHA calculations employ the Cornell-McGuire approach, considering a unified earthquake catalog, seismogenic source models, and ground motion attenuation. Seismic hazard maps are generated for peak ground acceleration (PGA) and spectral accelerations (SA) at different periods. The results are compared with observed ground motion data, providing valuable insights for seismic engineering design and hazard mitigation. The study enhances understanding and evaluation of seismic hazards in the region, contributing to improved seismic risk assessment and design practices (P#21)

In collaboration with fellow researchers, I developed a tsunami hazard assessment map for the Chilean seismic gap. This region, situated between 17°S and 30°S and 67°W and 74°W, is highly seismically active due to the convergence of the Nazca and South American tectonic plates. By utilizing synthetic simulations, we evaluated the potential tsunami hazards in the area, considering past destructive earthquakes and tsunamis. This work contributes to the mitigation of risks associated with seismic events in this region (P#19).

c. Himalayan Region: My research also encompasses seismic hazard assessment studies in the Himalayan region. By conducting seismotectonic modeling based on seismicity, focal mechanism, and fault patterns, I evaluated the hazards and risks associated with earthquakes in this geologically complex area (P#12).

In summary, my research encompasses the development of a new earthquake magnitude scale, the refinement of General Orthogonal Regression techniques for preparation of earthquake Catalog, and extensive seismic hazard assessment studies in regions such as Northeast India, the Chilean seismic gap, and the Himalayan region. These contributions significantly enhance our understanding of seismic hazards, improve magnitude estimation accuracy, and aid in mitigating risks associated with catastrophic earthquakes.
