My research focuses on understanding the processes that govern natural and anthropogenic hazards. These studies incorporate large quantities of remote sensing data such as space-based differential interferometric synthetic aperture radar (DInSAR), GPS data, seismicity and gravity, in order provide insights into the nature and scale of these hazards.  Specific projects focus on improvements in the quality of those data, development of innovative analysis techniques and assimilation into geophysical models of the underlying processes.  As part of that effort we investigate the implications and consequences of hazards such as earthquakes, volcanoes, landslides, groundwater extraction, and induced seismicity on infrastructure and society. 


Current Research

Induced Seismicity

In one of several induced seismicity projects I collaborate on, we identified the first frack induced earthquakes in North America. Induced seismicity is largely caused by the disposal of wastewater produced during oil and gas operations. Up until this work, the direct triggering of events by fracking itself was considered rare or even nonexistent. This result provides new insights into the mechanisms surrounding induced seismicity. 

Volcanic Hazard

Campi Flegrei caldera is one of the most hazardous volcanic areas in the world because of its close proximity to the city of Naples, a city of approximately 3 million people where almost 1 million people live within the caldera itself. We are applying advanced DInSAR time series analysis at Campi Flegrei and obtained vertical and horizontal components of ground deformation at unprecedented spatial and temporal resolutions over a 20-year time period. Although the area underwent continuous slow subsidence from 1993 through 1999, moderate uplift began in 2010 and substantially increased through 2012, reaching approximately 13 cm by 2013, suggesting that new magma injected at shallow depths presents increased risk to the local and regional population. We also modeled the observed deformation to determine magma depth and volume for both the subsidence and uplift epochs. Both the inflation and deflation mechanisms involve large, extended sources in a layered hydrothermal system whose location is controlled by the caldera structure and stratigraphy.

Twitter Data and Earthquake Shaking

Earthquake intensity is one of the key components of the decision-making process for disaster response and emergency services. Here we use advanced big data analytics to process both social media data – Twitter feeds – and physical sensors – seismographs – to jointly estimate the ground shaking for the M6.0 South Napa, CA earthquake in near real-time.  We showed that, in the minutes after the event, this joint analysis provided better estimates of location and magnitude of ground shaking, critical information for effective emergency response (Kropivnitskaya et al., 2016, 2017).
