The answers to this quiz appear in blue below each question.

1. Averaged over the entire geographic area of the region, which is larger?
(A) The average number of people per square kilometer. (B) The average number of volcanoes per 1000 square kilometers.

Answer: A
The size of the Kamchatka Peninsula is around 472,000 square kilometres, and the population is around 460,000, so the average number of people per square kilometer is almost 1. There are an estimated 329 volcanoes within this area, or about 0.70 volcanoes per 1000 kilometers.

2. Which is closer to the image area?
(A) The nearest point along the path of annularity of the first solar eclipse of 2003.
(B) The location where a cargo ship spilled tens of thousands of bathtub toys during rough seas in the early 1990s.

Answer: B
At its closest point to Kamchatka the path of the annular solar eclipse of May 2003 was over 4000 kilometers away, off of Greenlandís western coast. The toys were spilled into the North Pacific Ocean near the International Date Line, about 1600 kilometers from Kamchatka.

3. Which is smaller?
(A) The population of the region at the beginning of the 18th century.
(B) The population of the region at the beginning of the 20th century.

Answer: B
At the start of the 18th century the local native population of Kamchatka was about 20,000. The indigenous population was reduced to about 8000 by the mid-18th century. At the start of the 20th century the number of Russian migrants was about 2500 and the indigenous population was about 5000.

4. Which occurred earlier?
(A) Completion of a monument commemorating the seafarer who founded what is now the regional capital city.
(B) The attack on the port of the city and defense of the port by a 44-gun frigate.

Answer: A
A monument to the famous explorer Vitus Bering, believed to be oldest monument in the Russian Far East, was crafted in St. Petersburg between 1823 and 1826 and now stands in Petropavlovsk, near the harbour from which Bering started his expedition to America. The defense of Petropavlosk by the 44-gun frigate, the Aurora, occurred during the British-French attack of 1854. (Note: A monument to Vitus Bering (circa 1966) also exists on Bering Island in the Aleutians.)

5. Which is smaller?
(A) The number of masts of the ship upon which the aforementioned seafarer sailed during the last voyage of his or her lifetime.
(B) The number of animals first identified and named after the naturalist who sailed with the seafarer.

Answer: A
In 1741 naturalist Georg Wilhelm Steller set sail on the St. Peter, with Vitus Bering on the journey to find the Alaskan coast. The St. Peter was a single-deck two-mast ship. During the voyage, Steller identified the now-extinct Steller's sea cow and the spectacled cormorant, and described many other Alaskan species, including Steller's sea lion, Steller's jay, Steller's sea-eagle, and the northern fur seal.

6. Within the region, which is further north?
(A) The main military base.
(B) The most important lake-environment spawning ground for anadromous fish.

Answer: A
Rybachiy military base is located at the next major inlet south from Avacha Bay/Petropavlovsk. The rivers and lakes of Kamchatka are renowned for incredibly abundant fish and animal life. Kurilskoye Lake (or Kuril Lake), is considered to be the largest lake-environment spawning ground for sockeye (red) salmon in Asia, and is located at the far southern tip of Kamchatka.
