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.
