The findings, published in Communications Earth & Environment in 2026, show that fresh magma is injected into reservoirs rather than left over from past eruptions. The work draws parallels with massive systems like […]
New research reveals more about the magnitude of January eruption, as researchers call for better preparedness. The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January created an initial wave 90 metres high – almost the height of the Statue of Liberty (93m) University of Bath tsunami expert calls for better warning systems to detect […]
