The Earth is a beautiful and wondrous planet, but also frustratingly complex and, at times, violent: much of what has made it livable can also cause catastrophe. Volcanic eruptions create land and produce fertile, nutrient-rich soil, but they can also bury forests, fields, and entire towns under ash, mud, lava, and debris. The very forces that create and recycle Earth’s crust also spawn destructive earthquakes and tsunamis. Water and wind bring and spread life, but in hurricanes they can leave devastation in their wake. And while it is the planet’s warmth that enables life to thrive, rapidly increasing temperatures are causing sea levels to rise and weather events to become more extreme. Today, we know more than ever before about the powerful forces that can cause catastrophe, but significant questions remain. Why can’t we better predict some natural disasters? What do scientists know about them already? What do they wish they knew? In Dangerous Earth, marine scientist and science communicator Ellen Prager explores the science of investigating volcanoes, earthquakes, tsunamis, hurricanes, landslides, rip currents, and—maybe the most perilous hazard of all—climate change. Each chapter considers a specific hazard, begins with a game-changing historical event (like the 1980 eruption of Mt. St. Helens or the landfall and impacts of Hurricane Harvey), and highlights what remains unknown about these dynamic phenomena. Along the way, we hear from scientists trying to read Earth’s warning signs, pass its messages along to the rest of us, and prevent catastrophic loss. A sweeping tour of some of the most awesome forces on our planet—many tragic, yet nonetheless awe-inspiring—Dangerous Earth is an illuminating journey through the undiscovered, unresolved, and in some cases unimagined mysteries that continue to frustrate and fascinate the world’s leading scientists: the “wish-we-knews” that ignite both our curiosity and global change.
A common perception since the 1970s was that lower flows on the Peace River resulting from regulation precluded the generation of flood levels that would inundate perched basins that are separated from the open-water flow system. However, some literature references and local inhabitants have said that ice jams also played a role in some flood events. The initial objective of this study was to determine the relative role of ice jams in flooding in the Peace-Athabasca Delta (PAD). Assuming ice jams to be a significant factor, a second objective was to determine the hydrometeorological conditions that lead to their generation near the PAD and a third objective was to determine what role flow regulation has had on their formation. The study uses analysis of hydrometric data in conjunction with various historical and local sources to show the extent to which open water floods could flood the higher elevations in the PAD.
