Academic misconduct that is subject to disciplinary measures includes, but is not limited to, engaging in, attempting to engage in, or assisting others to engage, in cheating, impersonating a registered student at a Quiz, submitting false records or information, and falsifying or submitting false documents. Disciplinary measures are outlined in the section on Student Conduct and Discipline (http://www.calendar.ubc.ca/vancouver/index.cfm?tree=3,54,0,0) of the UBC Academic Regulations. An 8.3 magnitude earthquake strikes the coast of central Chile (red dot on map below), triggering tsunami warnings and coastal evacuations. Lasting three minutes, this powerful earthquake occurs along the convergent boundary of the Nazca and South American tectonic plates. Imagine that YOU are on the ground or main floor of a 2-storey concrete apartment building on the coast of central Chile , a few kilometres from the epicentre. Describe in 2-3 sentences or in point form how YOU would be affected physically (for example, would YOU be able to remain standing if YOU were already standing), what YOU would have heard , and what YOU would have seen happening to your household contents (items in bookcases, plates and glasses on shelf in kitchen, photo frames hanging on walls, etc). IMPORTANT : Write in your own words . Remember, copying/pasting from the Course Notes and/or from websites, documents, etc. is a form of cheating. This is academic misconduct that is subject to disciplinary measures.

As I am only a few kilometers away from the epicenter, I would definitely not be able to remain standing, the shaking of the ground would certainly bring me to my knees if not lying ﬂat on the ground. Soundwise, I would be hearing the warning sounds of the costal guards as there will be a tsunami. As for sounds of the earthquake itself, it depends on how deep within the ground it took place. Lastly, the intensity of a 8.3 magnitude convergent boundary earthquake would have devastated my household items, everything would be thrown off away from their original loca±on.
