Earthquake deformation with Sentinel-1

During this webinar, we will employ RUS to learn how to study earthquakes. We will analyse the earthquake occurred on May 4, 2018 at the Hawaii Island, that was triggered by the eruption of Kilauea Volcano on May 3, 2018. We will use Sentinel-1 SLC products to derive the deformation caused and combine it with geological data.
We will show you how to access the RUS Service and how to download, process, analyse and visualize the free data acquired by the Copernicus satellites.


Background

Earthquakes occur very often worldwide, especially in volcanic regions like Hawaii. They can be caused by tectonic faults, by the movement of magma in volcanoes (volcano tectonic earthquakes) and be related to dike intrusion.

The earthquake occurred in the south-east of the Hawaii archipelago on May 4, 2018 at the Hawaii Island, was of magnitude of Mw 6.9 and produced around 5 meters of fault slip. It is the largest earthquake affecting this region after the one at 1975, where 2 people were killed and another 28 were injured. This event was related to the new lava outbreaks at the Kilauea Volcano and the aftershock events continued until August 2018. The earthquake produced a minor tsunami that reached a maximum height of 40 cm in Kapoho, 20 cm in Hilo and 15 cm in Honuapo.

Hawaii region is known as one of around 60 hotspots that exist in the world and its islands are formed due to the continuous flow of magma towards the surface. The tectonic plate below them is moving to a north-west direction while the hotspot remains at the same location, creating new volcanoes. This is the reason why the youngest island is located to the south-east and why only the volcanoes at the half south part are active. Seismic activity will always take place in such regions and sometimes it can also be related to volcanic eruptions.
