Earth science news covering geology, seismology, volcanology, plate tectonics, and planetary surface processes.
Researchers at San Jose State University determined the San Andreas Fault is moving at a constant, accelerated rate over the last 10,000 years. This finding challenges previous assumptions of slowing movement and aligns with north coast measurements, occurring as stress levels near Los Angeles reach their highest point in a millennium.
The article argues that the 1883 Krakatau eruption established modern volcanology by enabling real-time global communication of its impacts. It contends that the event provided foundational evidence for how volcanic aerosols influence climate, agriculture, and human history through atmospheric cooling.
The article examines the 1986 Lake Nyos disaster in Cameroon, where a limnic eruption released carbon dioxide, killing approximately 1,700 people. It details the geological mechanisms behind the event and highlights ongoing scientific efforts to monitor volcanic lakes for similar catastrophic gas releases.
A magnitude 7.2 earthquake struck southern Peru, causing structural damage in Ayacucho and Cusco regions. Tremors were felt nationwide, including in Lima where approximately 9,000 properties lost power. No deaths were reported, though injuries occurred and aftershocks followed near Coracora.
