A Block Geography 12 -Thursday we looked at earthquakes and the seismic gap concept (focusing on Izmit Turkey in 1999). Today....Oh today we look at Tsunamis and the west coast of North America. We'll watch sections of the Discovery Channel documentary "America's Tsunami: Are we Next?" You will have two questions to work on tonight in your week five package:
How do Tsunami’s work? from p.11 &
Why can tsunamis cause such damage and devastation? What are some characteristics of the wave that factor into how much damage it could cause? How do coastal or shoreline features factor into the extent of damage? What role could a warning system play? How effective would a warning system be for the west coast of Vancouver Island? Why?

The devastation of last year's Boxing Day earthquake and tsunami in Southeast Asia offers vital lessons for the west coast of North America
By Jodi Di Menna and Steven Fick
In the year since a massive earthquake and tsunami rocked the Indian Ocean, the question "What if it happens here?" has gained urgency in western North America. The geology of the Cascadia subduction zone off the Pacific coast is so strikingly similar to that of Sumatra that scientists in British Columbia have used data from last year's disaster to refine models of how a megathrust earthquake — on the order of magnitude 9.0 — would affect the province's coast.
"The Sumatran earthquake was the type closest to what we expect in Cascadia," says John Cassidy, a seismologist at Natural Resources Canada in Sidney, B.C. "We set out to learn as much as we could from what occurred in Sumatra so that we could be better prepared when our big one happens."
Geological deposits and coastal First Nations lore indicate that large earthquakes have hit the West Coast every 200 to 800 years, and since the last one shook the region 305 years ago (the article is 10 years old so it is 315 now), scientists believe Cascadia could be ready to rupture at any time. In fact, in September (2005), Vancouver Island slid to the west about the width of a pencil, an event that occurs every 14 months and increases pressure along the fault line. "This slipping motion means we're one step closer to a big earthquake," says Cassidy.
The Sumatran experience gave scientists an idea of what to expect when it does happen. Using information gathered from that event, Cassidy and his colleagues plotted the same pattern of aftershocks and crustal deformation onto a map of the North American coast .
Predictions by computer models were largely confirmed by the Sumatran events, but in some cases, there were unexpected variations. Shaking was stronger than expected and felt farther inland, and the tsunami flooded higher up on shore and with more variation from place to place than scientists had anticipated.
These insights will eventually make their way into building codes and engineering designs in earthquake- and tsunami-prone areas, but more immediately, the Sumatran disaster has led authorities to adjust their reaction strategies by adding warning systems and by increasing public awareness.
"Educating people to be better prepared is the most important aspect," says Cassidy. "The Boxing Day images were a graphic reminder of what can and likely will happen in the future. The key is to use the information and learn from it."
B & C Blocks Social Studies 11 - Last week we looked at the five major political parties, their platforms and tried to select a party that most represents your beliefs. Today you'll take a look at other ways of influencing government such as civil disobedience, mass media, pressure groups and lobbyists (if you're good we may watch the first bit of the movie "Thank You for Smoking".
You'll have to answer the following questions:
- What is a pressure group? What is a lobbyist? How do they influence government?
- What is the role of the media in the political process (think news, reporting, campaigns, and advertising)?
- What is civil disobedience? What are the three "guidelines" for practicing civil disobedience? Should the Sierra Club of Canada allow acts of civil disobedience to be done in their name in order to block the development of the Northern Gateway or Trans Mountain Burnaby pipelines? Would you? How? Why or Why not?

The types of Mass Media include: Print media encompasses mass communication through printed material. It includes newspapers, magazines, booklets and brochures, house magazines, periodicals or newsletters, direct mailers, handbills or flyers, billboards, press releases, and books. Electronic media is the kind of media which requires the user to utilize an electric connection to access it. It is also known as 'Broadcast Media'. It includes television, radio, and new-age media like Internet, computers, telephones, etc. With the advent of Internet, we are now enjoying the benefits of high technology mass media, which is not only faster than the old school mass media, but also has a widespread range. Mobile phones, computers, and Internet are often referred to as the New-Age media. Internet has opened up several new opportunities for mass communication which include e-mail, websites, podcasts, e-forums, e-books, blogging, Internet TV, and many others which are booming today. Internet has also started social networking sites which have redefined mass communication all together.
American abolitionist/author/philosopher Henry David Thoreau lectured on "The Rights and Duties of the Individual in relation to Government" from which came the idea of civil disobedience. His belief was that as a citizen you do have an obligation not to commit injustice and not to give injustice your practical support. According to Thoreau, this means that if a law is unjust, and the legislative process is not designed to quickly get rid of it, then the law deserves no respect and it should be broken hence being civilly disobedient. So for us a modern day example may be the Keystone XL Pipeline project or the Embridge Northern Gateway Pipeline project. The Canadian chapter of the Sierra Club recently put an online poll on their website, to which about 1900 supporters responded. About nine in 10 felt “the climate crisis is so urgent that traditional legal campaigns are no longer sufficient.” They have chosen, however, not to practise civil disobedience. Should they?

D Block Criminology 12 - Today your journal / blog entry is to post your response to Friday's question:
What are the short and long term impacts on victims of Crime? Use Harper in the Law & Order episode you watched on Friday and Chapter 3 pages 54-7 in CRIM textbook to help.
Next, I'd like you to find an article (news story) about a victim of crime and for that you should outline the impacts of the crime on them. Finally, using the two stories (one fictional and one real) explain what we should do to mitigate (soften the impact) the impacts of crime on victims (be realistic). Don't forget to find stories on crime in Canada check out: CANOE CNews Crime site...or the Toronto Star Crime site...or Global News Crime site...or the Huffington Post Canada Crime site...or the Vancouver Sun Crime Blog
