K. Michailos, PhD

Hi 👋, my name is Konstantinos.

I am an observational seismologist. My research focuses on understanding seismotectonic processes, using high-quality earthquake catalogs, seismic imaging, and multidisciplinary approaches and datasets.

Research Interests

Microseismicity detection, location and characterization
Passive seismic imaging (e.g., receiver functions, ambient noise tomography)
Tectonic stress analysis

Current Project

We use ambient noise tomography (ANT) techniques to map the subsurface structure beneath the geothermal fields in Tuscany, Italy.

Research projects

Moho depths and receiver functions

We map the depth of the Moho discontinuity beneath the European Alps using teleseismic earthquake information (receiver functions) based on the AlpArray Seismic Network and other large scale passive experiments (Michailos et al. 2023).

Codes for this project are available here.

Moho discontinuity depth map for the broader European Alpine region.

Intermediate depth earthquakes, central Himalayas.

Intermediate-depth earthquakes beneath the Himalayas

We re-asses the "unusual" intermediate depth earthquakes, taking place beneath the central part of the Himalayan orogen. Our approach involved employing deep-learning-based earthquake detection methods (Michailos et al. 2021).

Scripts for this project are available here.

Crustal thermal structure and exhumation in the central Southern Alps, New Zealand

We use seismological and geological datasets to model the thermal structure beneath the Southern Alps and estimate the rates at which the Alps are being uplifted (Michailos et al. 2020b).

Codes for this project are available here.

Earthquake hypocenter profile with temperature isotherms and exhumation rates.

Microseismicity focal mechanisms, central Alpine Fault, New Zealand.

Microseismicity and tectonic stress near the central Alpine Fault

We compile a long duration microseismicity earthquake catalog near the central section of the Alpine Fault and observe shallow seismogenic cut-off depths near Aoraki/Mount Cook (<8 km) (Michailos et al. 2019).

We determine the crustal stress regime near the central Alpine Fault using first motion polarity focal mechanisms and stress inversions. We observe remarkably consistent stress orientations in both space and time (Michailos et al. 2020a).

Fieldwork

My work mainly involves staring at computer screens, but I've also been fortunate enough to to do fieldwork in different parts of the world.
