ALOS detected the surface rise at the New Georgia islands caused by Solomon earthquake

Japan Aerospace Exploration Agency succeeded to detect the surface deformations at the New Georgia islands, i.e., the new Georgia, Kolombangara, Rendova, and Tetepare island of Solomon islands, caused by the M8.1 Earthquake occurred on April 2 using the PALSAR Interferometry (Fig. 1). The images were acquired on April 16 and March 1, both using the FBS34.3 HH polarization in ascending path. It is interpreted that the lands were uplifted in the independent directions near the epicenter. The maximum uplift to the satellite direction within the New Georgia island is measured 2.2 meter (number of color cycles in Fig 2, 18, times a half of wave length, 11.8 cm). The report of April 10 for uplift at the west of New Georgia Island was confirmed by the PALSAR interferometry.
