The earthquake stress drop is a key parameter that represents the difference in stress levels on a fault before and after an earthquake. Calculating it is important to understand the energy released during earthquakes, understand the physics of the earthquake
New Paper Alert!
A new paper titled “Evolution of Shear Rupture Along a Prescribed Interface Using the Discontinuous Deformation Analysis Method” has been published. You can access it here.
Intermittent Criticality and Multi-Scale Processes: Unraveling Large Slip Events on Rough Laboratory Faults
This paper had in our workplace an ironic codename “Neverending paper” – the story of this paper starts already in 2016. And finally, our study entitled “Intermittent criticality multi-scale preparatory processes leading to large slip events on rough laboratory faults
Cascade and pre-slip models oversimplify the complexity of earthquake preparation in nature
It all started about 4 years ago, during the pandemic, when we started discussing different studies on pre-seismic observations and we realized that we were both working in the field but basically reading different sets of observational papers and understanding
Months-long seismicity transients before the 2023 Kahramanmaraş earthquake, Türkiye
On February 6th, 2023, the devastating magnitude MW 7.8 Kahramanmaraş earthquake in South East Türkiye ruptured multiple fault segments of the East Anatolian Fault Zone separating the Anatolian and Arabian tectonic plates. This earthquake and its aftershock sequence was followed by a
Induced earthquake potential in geothermal reservoirs
We have a new publication on our main findings from our studies at The Geysers geothermal field and how the evolution of seismic injection efficiency can be an effective proxy to monitor seismic hazard and probability of a reservoir to
Preparation Phase of an Mw 5.8 Earthquake in the Sea of Marmara Offshore Istanbul
We just recently published our new study with Virginie Durand as first author, where we investigated the seismicity preceding the occurrence of a M 5.7 event in the Marmara Sea that was widely felt offshore Istanbul. The study has been
Resolving the Moho depth in the Sea of Marmara region
If you’re interested in how the Earth’s crust around Istanbul in Turkey is shaped by both the ancient processes that formed the country and the present day forces that continue to deform it, then have a look at the recent
Resuming operation !
Although the group SAIDAN has continued its activity, I (Patricia Martínez-Garzón) was on twin maternity leave. For that reason this website was not updated for a while. We will now continue posting our upgrades and I will post weekly from
Controlling fluid-induced seismicity in geothermal projects
In these times when geothermal energy is being associated to large EQs and thus not feasible, we showed that it is possible! It is possible to perform geothermal development to extract energy without causing earthquakes felt at the surface! In
