The recent earthquake in Indonesia raised the height of the bottom of the Javanese Sea and the north-eastern coast of Lombok Island by 30 centimeters, according to the NASA Jet Propulsion Laboratory.
On Sunday, north of the Indonesian island of Lombok, there was a strong earthquake with a magnitude of 7 on the MMS scale and subsequent aftershocks, whose strength was 5.4 and 4.3 points. This morning in the vicinity of the island there was another similar event, whose magnitude approached the mark of 6.1 points.
As reported by the local agency Antara, the victims of the earthquake on Sunday were 347 people. Sutopo Purvo Nugroho, representative of the national disaster management agency, announced the death of 131 inhabitants of the island. Another 20 thousand people were left without a roof over their heads.
A similar event, which occurred in April 2012 off the coast of Sumatra, led to the split of the Indo-Australian tectonic plate into two halves, which is why scientists closely monitor all the powerful earthquakes in Indonesia and the surrounding countries.
The images obtained with the Sentinel-1A and Sentinel-1B probes before and after the earthquake showed that it did not lead to the appearance of new cracks and splits in the fragments of this plate. According to current estimates by NASA, the earthquakes have lifted the height of the north-eastern tip of the island of Lombok by several dozen centimeters, and similarly altered the relief of the bottom of the Yavan Sea and the Lombok Strait, which connects it with the Indian Ocean.
At the same time, the central part of the island sank a little – its height in some regions decreased by about 15 centimeters. It is not yet clear how the new tremors changed the face of the island and whether they will cause more serious consequences.
