Shortly after North Korea conducted what’s believed to be its first successful test of a hydrogen bomb (and its sixth nuclear test in total), China’s Nuclear Safety Administration said on Sunday that it would begin emergency monitoring for radiation along its northeastern border with North Korea, according to Reuters.

The emergency response was set at “level 2,” the second-highest grade on a four-tier system, according to the Times of Japan. The NSA did not indicate whether any radiation had been detected.

The dynamics of the standoff between the US and North Korea have shifted dramatically in the past week.

First, the North started with an unexpectedly sharp provocation - launching a missile over the Japanese island of Hokkaido - before following that up with its sixth nuclear test. Also, judging by the size the earthquake detected in the country’s mountainous North on Sunday morning, North Korea may have been telling the truth when it said it conducted what it described as its first hydrogen bomb test.

Following remarks from the leaders of South Korea and Japan, President Donald Trump has responded to North Korea's latest "perfect" nuclear test, emphasizing that South Korea's "talk of appeasement will not work," and that Kim Jong Un and his government "only understand one thing!" He added that the nuclear test is an embarrassment...to China.

Two weeks ago, we reported that Brian Wilcox, a former member of the NASA Advisory Council on Planetary Defense, had shared a report on what the Space Agency considered one of the greatest natural threats to human civilization: the Yellowstone "supervolcano."

Following an article published by BBC about super volcanoes last month, a group of NASA researchers got in touch with the media to share a report previously unseen outside the space agency about the threat Yellowstone poses, and what they hypothesize could possibly be done about it. 

On Tuesday, just as Hurricane Harvey was peaking, we reported that according to ship-tracking data compiled by Bloomberg, as well as MarineTraffic real-time tracking, at least 25 tankers carrying almost 17 million barrels of imported crude oil were drifting near Texas and Louisiana ports, unable to offload because of closures from Tropical Storm Harvey.
