The tsunami that hit the Pacific island of Tonga over the weekend has caused sea levels to ‘peak’ in Portugal – the highest incident (an increase of 40cm) was registered in Ponta Delgada (Azores). Funchal (Madeira) saw the sea level there increase by 20cm – and on the mainland the area most affected was Peniche, with a rise of 39cm. IPMA (meteorological institute) has attributed the swells to the “atmospheric shock resulting from the explosion” of the Hunga-Tonga-Hunga Ha’apai volcano, which is still in a process of eruption.
