Presently, “Should I Blow?” might be answered with a resounding “Yes!” in the near future. Although volcanologists and seismologists can trace the current period of Katla unrest to 1999 and even a couple of times over the past year tremors and earthquakes have spurred concern of an imminent eruption, the current level of unrest is quite high. In fact, after a long period of magnitude-three tremors, a magnitude-four quake was detected last week.

More rumblings from the Canary Islands this morning but, as of now, nothing substantial enough to shake loose the mega-landslide that is expected to trigger the mega-tsunami which will lead to the mega-submerging of the entire eastern coast of the U.S. At least, that’s the hypothesis.
You won’t find this on the front page of the New York Times or anywhere on CNN.com, but if you have your ear to the tracks you might’ve heard rumblings from far off in the North Atlantic Ocean where, near the Canary Islands, there have been an incredible number of earthquakes recorded in the past week — 620 and counting, 400 in just four days!
If the title of this article didn’t quite grab your attention, then this will: “Approximately 9,000 National Guard Soldiers and Airmen on State Active Duty are supporting the simulated earthquake relief operations, including mock route clearing, search and rescue, and security operations across Alabama, Arkansas, Illinois, Indiana, Kentucky, Missouri and Tennessee.”
Why is this area so prone to such frequent earthquakes? It’s what amounts to the Perfect Storm of tectonics. Five of Earth’s massive plates meet in this area and grind upon one another.
[Geology expert and ImpactWeather StormWatch Manager Fred Schmude guest posts about the terrible events in Japan today.] Last night’s massive earthquake occurred near the northeast coast of Honshu Island in Japan at 0546Z (11:46pm CST) on Friday March 11, 2011. The epicenter of the quake was located at 38.32N and 142.37E or about 81 miles […]
The strong and very shallow quake was located at 43.59S and 172.71E, or about three miles north northwest of Christchurch. The depth of the focus was estimated to be only about 3 miles deep. Strong seismic aftershocks between 4.5 and 5.5 on the Richter Scale will likely occur over the next two to three weeks as the initial break in the Earth’s crust slowly reaches equilibrium. Buildings already weakened by the initial strong quake could collapse with those additional strong aftershocks.
Is magma near the surface of the earth a bit more “anxious” near Conway, Arkansas these days? Magma, a molten-rock mixture of gas and solids, is always on the move, but when it’s a bit more active than normal it can cause tremors (aka: earthquakes). Such is the case near Guy, Arkansas (near Conway). The […]
It’s possible that yesterday’s Norman quake could be considered a foreshock.
The tsunami caused by the 8.8-magnitude earthquake that hit Chile on February 27 has had devastating affects on Chile’s fishing industry. According to Gonzalo Olea, a spokesman for Chile’s National Confederation of Small Fishermen, an estimated 1,000 fishing boats close to shore were destroyed by the tsunami. However, some of the larger ships that service […]
