Deep earthquakes: Observations, Experiments and Explanations

RAS Specialist Discussion Meeting May 2019

A Royal Astronomical Society Specialist Discussion Meeting organised by *Simon Hunt (UCL); Andy Nowacki (Leeds)

The mechanisms that drive ‘deep earthquakes’—those deeper than ~60 km—are poorly understood. Pressure at these depths prevents brittle sliding on faults and the alternative mechanisms have not been conclusively proved. This may change, however.  In recent years, experimental techniques have advanced such that the harsh conditions of the deep mantle are now easier to reproduce, in the lab and computers; we have benefited from the rapid increase in the volume and quality of seismic data available to probe such events, as well as the ability to forward model seismograms; advances in geodynamics and other fields have paved the way for improvements in our understanding; and many large, deep events have occurred in the past decade. This specialist meeting will discuss the current and future state of our understanding of deep earthquakes and generate new ideas on how to tackle the  long-standing question of their origins.
 

Admission to Specialist Discussion Meetings is free for RAS Fellows, £15 for non-fellows (£5 for students), cash or cheque only, collected at the registration desk.  Admission to the subsequent Open (Monthly A&G) Meeting of the Royal Astronomical Society is open to all, at no charge.
