| Venue: | D N Wadia Lecture Theatre |
| Details: | The Earth’s Inner Core is a solid sphere primarily composed of Iron. Despite its relatively small size as compared to the Earth’s volume, it plays a critical role in the dynamics and overall functioning of our planet. Understanding the inner core’s properties, such as composition and behavior under extreme temperature and pressure is essential for insights into the thermal evolution of the planet. Advances in seismology have revealed complexities within the Inner Core, such as anisotropy and possibly the presence of an innermost inner core. Combined with geodynamic modeling, I try to simulate the growth of the inner core to understand the processes causing its present-day anisotropy to answer questions like; How is global inner core anisotropy generated during inner core growth? What caused the present-day orientation of anisotropy? Our understanding of the inner core not only provides a window into the past but also offers critical information for predicting the planet’s geological and magnetic behavior. It also contributes to broader geophysical models and theories regarding planetary evolution. |
