This module is the second in the four-part Volcanic Ash series. It provides information about the geological, and geophysical processes related to volcanic activity and volcanic ash in the atmosphere and on the ground. It discusses four types of volcanic eruptions and describes six major volcanic hazards:
Tephra
Pyroclastic flow
Lahar
Lava flow
Volcanic gas
Tsunami

I am giving this a low rating because while the lecture was particularly short, it lacked a lot of necessary information. There is one question on the quiz that needs to fixed- specifically the one asking to "Order the steps in the process of an explosive volcanic eruption. Use the selection box to choose the answer that best matches the statement.". The lecture did not cover this question at all. After numerous (I seriously mean like 40) tries, I could not get the question right. Not even my professor or tutor could. This is ingroguent with the material on the lecture and is preventing students from getting a better grade. Please fix this issue. I know not a single student who got that question correct.

I'd prefer a little less reading and a little more audio/video as I comprehend the material better that way.

was very difficult to learn the process of explosive eruptions, or at least to answer the quiz question.

The question that asks the steps of volcanic eruption needs to be greatly modified. No matter how i organized the steps, i still got the question wrong! That question needs to be revised as soon as possible!!!

One of the questions is poorly explained and laid out for users to understand. Based on all the questions the only one I missed was the question that asks us to order 7 different events and it is poorly written in the test or poorly explain in the section. Even the professor teaching about this had trouble answering this same question. Do fix that question.

There is one question on the quiz that absolutely SUCKS. It's not covered in the material and should be thrown out.

This module is very easy to understand and fun to do. I recommend this to anyone living near a volcano, wanting to learn more about volcanoes, or studying the weather. It was very informative.
This module will prepare the learners to:
Identify the geological elements involved in volcanic eruptions
Locate currently active volcanoes and major fault lines/plates in the world
Describe the process of an explosive volcanic eruption
Identify eruption types and describe their ash dispersion patterns
List the most common volcanic hazards and the threats they pose
Aviation, dispersion, volcanic ash, volcanism, explosive eruption, plinian, hawaiian, strombolian, vulcanian, plate tectonics, volcanoes, Mount Pinatubo, Eyjafjallajokull, tephra, pyroclastic flow, lahar, lava flow, volcanic gas, tsunami, societal impacts, agriculture, public, HYSPLIT, Mount Redoubt, climate, radiation balance, marine,
November 6, 2013: The Fall 2013 update of "Volcanic Ash: Volcanism" includes content focused on additional geographic regions of volcanic activity, including Africa and New Zealand. Sections 2.0 Eruption Dynamics and 3.0 Volcanic Regions contain new graphics illustrating tectonic plate motion and active volcanic areas. The 2011 Puyehue Cordón-Caulle and 2010 Eyjafjallajökull eruptions are put into historical context.
