A strong earthquake with an epicenter off the northeastern coast of Japan shook buildings all the way to Tokyo, leading to a tsunami warning for coastal areas of the northeast.

The first estimate of the magnitude was 7.4, but was then lowered to 7.3. The United States Geological Survey (USGS) explained there is no risk of a widespread tsunami for other areas in the Pacific, but a warning for a one-meter tsunami was issued for the coast of Miyagi Prefecture in northeastern Japan – the same area which was most hit by the 9.1 earthquake and consequent tsunami in March 2011. However, unlike that massive earthquake, this one poses no threat to the Fukushima power plant – no irregularities were reported at the site.

The 2011 earthquake caused a huge tsunami, much more than the Fukushima power plant was prepared to handle, causing radiation leakage, contamination of food and water and mass evacuations; the Japanese authorities handled the situation absolutely admirable, and a bigger crisis was averted.

As it seems, the geological situation in the area is still extremely volatile; many more such “smaller” temblors are expected, but an earthquake of that magnitude is very unlikely to happen again in the near future.

This Picture of the Week shows a stunning spiral galaxy known as NGC 4945. This little corner of space, near the constellation of Centaurus and over 12 million light-years away, may seem peaceful at first — but NGC 4945 is locked in a violent struggle. At the very centre of nearly every galaxy is a supermassive black hole. Some, like the one at the centre of our own Milky Way, aren’t particularly hungry. But NGC 4945’s supermassive black hole is ravenous, consuming huge amounts of matter — and the MUSE instrument at ESO’s Very Large Telescope (VLT) has caught it playing with its food. This messy eater, contrary to a black hole’s typical all-consuming reputation, is blowing out powerful winds of material. This cone-shaped wind is shown in red in the inset, overlaid on a wider image captured with the MPG/ESO telescope at La Silla. In fact, this wind is moving so fast that it will end up escaping the galaxy altogether, lost to the void of intergalactic space. This is part of a new study that measured how winds move in several nearby galaxies. The MUSE observations show that these incredibly fast winds demonstrate a strange behaviour: they actually speed up far away from the central black hole, accelerating even more on their journey to the galactic outskirts. This process ejects potential star-forming material from a galaxy, suggesting that black holes control the fates of their host galaxies by dampening the stellar birth rate. It also shows that the more powerful black holes impede their own growth by removing the gas and dust they feed on, driving the whole system closer towards a sort of galactic equilibrium. Now, with these new results, we are one step closer to understanding the acceleration mechanism of the winds responsible for shaping the evolution of galaxies, and the history of the universe.
