Just great. Some idiot is going to see these pictures of an idiot kayaking next to lava pouring into the ocean and standing on top of a recent bench and think they can do the same, try it and quite possibly get themselves hurt (if lucky) or dead (if not lucky). Very stupid.

A lava lake in Antarctica gives scientists a clear view of how volcanoes work
Science News, April issue
Studying volcanoes is a tricky business. Most active volcanoes hide their magma, pools of molten rock churning at temperatures up to about 2,300 degrees, beneath a rocky crust. When people can see magma firsthand, it usually means a volcano has blown its craggy top, violently spewing magma in the form of lava. Not ideal for scientists keen to learn about the inner workings of a volcano and the conditions that cause it to erupt.
But Antarctica's Mount Erebus, the world's southernmost active volcano, is different. According to Science News magazine, the ice-covered mountain has an open top, its lava lake exposed to the sky and anyone willing to peer inside. Despite its remote location — and an elevation of more than 12,000 feet — Erebus offers scientists one of the best opportunities to study the heart of a volcano.
The magazine reports that for the last four decades, researchers have focused on bubbles of water vapor, carbon dioxide and other gases that emerge through Erebus's magma. These bubbles, the magazine says, offer clues about a volcano's unique physiology — its stability, its origins beneath the Earth's crust and its ability to support microbial life — as well as insight into the inner workings of all volcanoes.
Researchers have set up microphones around the volcano's rim to listen to Erebus's burps, and they have set off explosives to record shock waves and map the mountain's insides.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~One of Azerbaijan's largest volcanoes erupts - PHOTOSESSION--<---be sure to click this link for images![ 08 April 2013 ]
A lot of cracks appeared in the territory as a result of volcano, one of the cracks spread out over 2 km
Baku. Kamala Guliyeva – APA. Akhtarma-Pashali volcano in Hajigabul region of Azerbaijan has erupted, head of the ANAS Institute of Geology's Mud Volcano Department Adil Aliyev told APA.
He said the eruption was recorded on April 1. The scientists of the Institute of Geology have carried out research in the area:
"This is one of the largest volcanoes of Azerbaijan. Volcano is located 35 km from Shirvan city - in the south-eastern Shirvan. The volcano erupted for the first time in 1948, this is the 7th eruption."
Aliyev said that along with mud the eruption also spouted a great deal of various rocks. "The volcano mud covered 18 hectares, the total area is 220 000 cu m. The average thickness of the spouted material is 120 cm. A lot of cracks have appeared as a result of the volcano. One of them is too big. It spread out over 2 km. The depth of the crack is 2 m, width between 30 – 80 cm. At present the volcano has calmed down. Usually flames are observed when mud volcanoes erupt. No flame is observed in this volcano," he said.
According to the department chief, the diameter of the volcano is about 10 sq km meters: "Several volcanic areas separated from each other are located in the crater of eruption. Every time eruption occurs in a separated volcanic area. 21 percent of mud volcanoes in Azerbaijan pull a lot of oil out of surface. This volcano is also spewing oil. Oil soaked into all wastes. It should be noted that there was also oil shale. All of them will be studied in the laboratory and concrete information about the oil and gas resources of the area will be obtained after the tests."

Getting information on volcanic plumes can be perilous work: the unbearable heat; the noxious gas; the jagged terrain.
So NASA found a new way to avoid putting its researchers in danger - military drones.
Last month, NASA researchers sent three drones into a sulphur dioxide plume emitted by Costa Rica's 3200-metre Turrialba volcano. The team, led by David Pieri of NASA's Jet Propulsion Laboratory in La Canada Flintridge, launched 10 flights with the 2.7-kilogram, twin-electric-engine Dragon Eye planes.
The drones recorded video and collected data using several remote-sensing instruments, sulphur dioxide and particle sensors and automatic atmospheric sampling bottles that measure sulphur dioxide concentration.
''Scientists believe computer models derived from this study will contribute to safeguarding the national and international airspace system and will also improve global climate predictions and mitigate environmental hazards - for example, sulphur dioxide volcanic smog, or 'vog' - for people who live near volcanoes,'' NASA said.
The Dragon Eye drone is built by AeroVironment, the Pentagon's top supplier of small drones.
Drone-makers want to sell their products for use as police helicopters, crop-dusters and hobby aircraft. Drones are not allowed to fly in the US without permission from the Federal Aviation Administration.
