tasks of a volcanologist 2 small questions

1. You’re the chief volcanologist for the US Geological Survey (USGS), based in Sacramento, California. At 10:30 a.m. on a Tuesday, you receive a report from a seismologist at the USGS in Pasadena, California, saying that there has been a sudden increase in the number of small earthquakes in the vicinity of Mt Shasta, California. You have two technicians available, access to some monitoring equipment, and a four-wheel-drive vehicle. At noon, you meet with your technicians and a couple of other geologists. By the end of the day, you need to have a plan to implement, starting tomorrow morning, and a statement to release to the press. What should your first day’s fieldwork include? What should you say later today in your press release?

(One paragraph for this answer).


2. The diagram below is a cross section of a hypothetical area. Place the lettered features (A through P) in the proper sequence, from oldest to youngest (left: oldest; right: youngest).

Hint: “C” is the youngest rock because it cuts across all other rocks; “P” is the oldest because it is underneath all other rocks.

Note: You don’t need to write the reason as I did above, this was meant to explain to you the reason why “C” is the youngest and “P” is the oldest.
