The earthquake was primarily strike-slip, meaning two tectonic plates slid past each other. These types of earthquakes are less likely to cause tsunami because their movement is primarily horizontal with minimal vertical movement of the ocean floor. https://t.co/3vWypuPqHi

Heroic and successful efforts were made to save working machines close to the edge of the #lava. The machines were being used to construct defensive walls against lava flow into ##Grindavík - the same walls along which workers drove the machinery to safety.
