Researchers have identified a potential second magma chamber beneath Nicaragua's most active volcano, which is situated near approximately 2 million residents. The discovery was made through recent geological investigations into magma flow patterns beneath the volcano.
Scientists compared sonar seafloor mapping taken before and after the 2022 Hunga Tonga-Hunga Ha'apai eruption, revealing physical changes to the underwater volcano that help explain the tsunami it triggered. The eruption's tsunami behaved differently from typical earthquake-generated waves, prompting researchers to investigate its distinct origin.
The article revisits the 1991 Pinatubo eruption, when scientists deployed instruments that detected volcanic unrest and issued an evacuation order shortly before a massive explosion killed over 800 people, saving hundreds of thousands more. It notes that despite this success, the forecast was largely an educated guess rather than a precise prediction, and that volcanology has since improved through better instrumentation and machine learning.
