Week 3 - Earthquakes

Most recently, Croatia has had one of the worst earthquakes in their history. December 29, 2020 a magnitude 6.4 struck near Petrinja, Croatia. Link: https://www.usgs.gov/news/featured-story/magnitude-64-earthquake-croatia

There are a few projects in the area that focus on Earthquake forecasting, warning, and response. TURNkey is one project in Europe that focuses on collecting data. https://earthquake-turnkey.eu/

• Operational Earthquake Forecasting (OEF) by collecting all available earthquake-hazard related information for the regions of interest (long-term) and by monitoring the regions with the multi-sensor-based earthquake information system (short-term). 
• Earthquake Early Warning (EEW) by distributing reliable information that an earthquake is happening as fast and efficiently as possible to all stakeholders hence mitigating earthquake losses. 
• Rapid Response to Earthquakes (RRE) by informing relevant stakeholders about the most probable damage scenarios.

One after effect from earthquakes that Croatia has been struggling with has been sinkholes. Dozens of holes showed up days after a 6.4 earthquake. "While landslides and sinkholes are known to be triggered by earthquakes, along with other strange geological phenomena such as liquefactions – where the solid ground begins to behave like a liquid – the sheer number of holes appearing around the two villages surprised and baffled experts. A month after the earthquake, there were almost 100 sinkholes spread over a 10 sq km (3.8 sq miles) area, with new ones opening every week." https://www.bbc.com/future/article/20210702-how-an-earthquake-created-a-village-full-of-sinkholes
