This document describes several types of volcanic hazards including tephra flows, lava flows, ash falls, mudflows, volcanic gases, caldera formation, and volcanic soil formation. It also discusses methods for monitoring volcanic activity such as satellite monitoring, earthquake and ground deformation monitoring, gas level monitoring, and studying groundwater. Diagrams illustrate the internal structure of a volcano and where different volcanic features are located.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Hazard
Any phenomenon that has the potential to cause disruption or damage to people and their environment.
For example, an earthquake can cause a tsunami.
Disaster
Natural disasters are slightly different. They are the effects of natural hazards on humanity.
For example, the tsunami in Indonesia caused a great amount of loss of property and more importantly lives.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Tephra flows down the side of a volcano.
120 mph driven by gravity.
Mostly with granitic and andesitic eruptions.
3.
4. Streams of molten rock that flows down the
side of a volcano.
Burns and buries everything in its path.
1 meter/hour…or as fast as 30 km/hr.
5.
6. When ash from an explosive eruption falls to
the ground.
Covers everything and piles up like snow;
collapses buildings.
Blocks out the sunlight for long periods –
Lowers temperatures.
7.
8. Mixture of water and rock flowing down the
slopes of a volcano.
Like wet flowing concrete that can not be
outrun.
Caused when snow melts quickly or eruption
causes a landslide.
Most often with steep sided composite cone
volcanoes.
9. Sulfur Dioxide.
Carbon Dioxide.
Kills people, trees, animals, and effects the
atmosphere.
LowersTemperatures
Air Pollution.
Acid Rain and Ozone Depletion.
WaterVapor is most common gas erupted
from volcanoes.
10. A caldera is not so much caused by an explosive
eruption “blowing” off the top of a volcano.
It is, rather, caused after magma, gas, and pressure
have been released from a volcano resulting in a
lack of support for the summit of the cone.
The cone then collapses as it becomes over-come
by its own weight.
A very large crater that
forms when the top of a
volcanic cone collapses.
11. Rock is broken down and weathered after an
eruption.
The easily weathered rock makes great soil
for farming.
