Book Description
The Herons take to the high seas to fend off pirates and rescue the heir to an empire in the newest adventure from John Flanagan, author of the worldwide bestselling Ranger's Apprentice! Includes BONUS content--a brand-new Ranger's Apprentice short story featuring fan-favorites Will and Maddie! In Hallasholm, Stig is contesting the annual Maktig competition to decide Skandia’s greatest warrior. But a late-night knock on the door brings someone Stig never expected to see again, along with a request the Herons are hard-pressed to refuse: a rescue mission of epic proportions. Across the ocean, the southern city-state of Byzantos is plagued by a crew of pirates who’ve kidnapped the son of Empress Justina. Slipping out of Hallasholm under the cover of darkness, the brotherband sets sail to recover the boy from his kidnappers, heading south to the island of Santorillos where a near-impenetrable fortress stands atop a cliff, surrounded by a lagoon—a caldera—formed by the crater of a volcano. In this explosive seventh book in the action-packed Brotherband Chronicles, the Herons battle pirates amid stormy seas as the fate of an empire rests on their shoulders.

Book Description
About 1.25 million years ago, a spectacular volcanic eruption created the 13-mile wide circular depression now known as the Valles Caldera, located in northern New Mexico. This revised & expanded edition marks the twentieth anniversary of the Valles Caldera Preservation Act, a visionary piece of legislation that transferred to the public domain a privately owned ranch (signed in 2000 by President Bill Clinton). The preserve was assigned to a board of citizens appointed by the president to manage it as a self-sustaining preserve. The experiment in semi-private land management ended in 2014 as the Valles Caldera was legislatively reassigned to the National Park Service.

Book Description
Large caldera collapses represent catastrophic natural events, second only to large meteoritic impacts. In addition, some calderas are densely populated, making the risk extreme, even for moderate eruptions. Understanding caldera mechanisms, unrest and the danger of eruption is therefore a crucial challenge for Earth sciences. Several key features of caldera behaviour have yet to be fully understood. Through a combination of case studies and theoretical modelling, the following topics are addressed in this volume: the conditions required to produce and to release large volumes of magma erupted during caldera formation; how magmatic feeding systems evolve before and after a caldera has formed; the processes that limit the behaviour of precursors to eruptions; how pre-eruptive precursors can be distinguished from those that drive unrest without an eruption; and given that post-collapse eruptions may occur across a wide area, the optimum procedures for designing hazard maps and mitigation strategies.

Book Description
Six-hundred-thousand years ago the largest volcano in the Western Hemisphere erupted covering much of what is now the Central United States in a thick layer of ash. The explosion left behind a massive caldera that today is known as Yellowstone National Park. Yellowstone volcanologist Milton Bainbridge discovers Yellowstone is about to erupt again and millions of Americans in thirteen states will parish if they cannot be evacuated from the deadly path of the fallout. Bainbridge mysteriously dies, leaving his assistant, Carlene Carlson, and volcanologist, Jason Trask to save the United States from the worst natural disaster in its history. To make matters worse, a little known terrorist group is planning on using the eruption of Yellowstone to topple the U.S. government. Trask and Carlson face off against a government unwilling to believe an eruption is eminent and a terrorist group that is conspiring to topple the United States in the aftermath of the natural disaster. Caldera is an action packed thriller with a high degree of technical accuracy.

Book Description
This volume aims at providing answers to some puzzling questions concerning the formation and the behavior of collapse calderas by exploring our current understanding of these complex geological processes. Addressed are problems such as:- How do collapse calderas form? - What are the conditions to create fractures and slip along them to initiate caldera collapse and when are these conditions fulfilled? - How do these conditions relate to explosive volcanism?- Most products of large caldera-forming eruptions show evidence for pre-eruptive reheating. Is this a pre-requisite to produce large volume eruptions and large calderas?- What are the time-scales behind caldera processes? - How long does it take magma to reach conditions ripe enough to generate a caldera-forming eruption?- What is the mechanical behavior of magma chamber walls during caldera collapse? Elastic, viscoelastic, or rigid? - Do calderas form by underpressure following a certain level of magma withdrawal from a reservoir, or by magma chamber loading due to deep doming (underplating), or both?- How to interpret unrest signals in active caldera systems?- How can we use information from caldera monitoring to forecast volcanic phenomena?In the form of 14 contributions from various disciplines this book samples the state-of-the-art of caldera studies and identifies still unresolved key issues that need dedicated cross-boundary and multidisciplinary efforts in the years to come. - International contributions from leading experts - Updates and informs on all the latest developments - Highlights hot topic areas and identifies and analyzes unresolved key issues
