Water stress a vital issue for mega-earthquakes
Scientists suggest a mechanism that explains how the most important earthquake ever occurred and the way greater than 50 years later one other massive earthquake in the identical area launched among the stress that had constructed up within the depth. … Continue reading
Diamond discovery beneath stress
For the primary time, scientists have discovered Earth’s fourth most ample mineral — calcium silicate perovskite — at Earth’s floor. Geology News — ScienceDaily
We should use central pressure deficit, not wind speed, to predict hurricane damage
New research provides a physical understanding for why central pressure deficit is a better indicator of economic damage from hurricanes than peak wind speed. Geology News — ScienceDaily
Crystals help volcanoes cope with pressure
Researchers have discovered that volcanoes have a unique way of dealing with pressure — through crystals. If enough crystals can develop in rising magma then a network of microscopic crystals can lessen the internal pressure of rising magma and reduce … Continue reading
