This allows for the detection and quantification of deformation or movement. This ALOS-2 co-eruptive interferogram showing the line-of-sight (LOS) fringes (12 cm/fringe). The descending track (path 77) interferogram shows the difference between May 28, 2021 and May 14, 2021. Satellite LOS is to the WNW (parallel bottom edge of interferogram) from an angle between 35-40 degrees from nadir. Interpretation is that this is the deformation due to a dike intrusion to the SE of Nyiragongo volcano (green triangle in center).</SPAN></P><P><SPAN STYLE="font-weight:bold;">Suggested Use: </SPAN></P><P><SPAN>This interferogram shows permant ground movement/deformation due to the recent earthquakes.
