Figure 2
Tectonic map of the Delhi region with the Trans- Himalayan Conductor (THC) superimposed on it. The earthquakes with magnitude M > 3.0 from 2001 to 10th June 2020 are plotted (stars) from the earthquake catalog prepared by NCS, New Delhi. Major tectonic features of the Himalaya; Main Boundary Thrust (MBT), Main Central Thrust (MCT) and Main Frontal Thrust (MFT) are shown along with the regional tectonic features including Mahendragarh–Dehradun Fault (MDF), Delhi–Hardwar Ridge (DHR), Moradabad Fault (MF), Sohna Fault (SF), Mathura Fault (MTF) and Great Boundary Fault (GBF). The fault plane solutions of the four past earthquakes are shown with black & white beach balls prepared from and the recent (12th April 2020, 10th May 2020 and 29th May 2020) earthquakes are shown with red & white beach balls. The stations used for computation of fault plane solutions are shown with black triangles and station numbers (1:NDI; 2:NRLA; 3: LDR; 4:JMIU; 5:BISR; 6:AYAN; 7:UJWA; 8:JHJR; 9:SONA; 10:KUDL). The tectonic features are from the files provided at BHUKOSH portal of Geological Survey of India (http://bhukosh.gsi.gov.in/Bhukosh/MapViewer.aspx). These features are overlapped on SRTM data of 90 m resolution (http://srtm.csi.cgiar.org). The figure is prepared using Generic Mapping Tools version 4.4.03.
