Scientists pinpoint tremors beneath Tanzania's Oldoinyo Lengai volcano
Researchers have traced tremor signals deep inside Tanzania's Oldoinyo Lengai volcano, locating them in three dimensions for the first time. The study reveals linked tremors at varying depths, providing insights into magma and gas movement. This unique carbonatite volcano's fluid, cool magma produced unexpected results that could improve eruption forecasting.
Martian volcanoes may have delivered ice to equator
AI에 의해 보고됨
Scientists propose that explosive volcanic eruptions billions of years ago transported water from Mars's interior to its equatorial regions, forming thick ice layers beneath the surface. This mechanism explains radar-detected ice in the planet's hottest area without relying on shifts in Mars's axial tilt. The discovery could aid future human missions by providing accessible water resources.
