The southern shores of Europe have seen their share of geological conflict. Africa is moving north, and Europe is in the way. There have been many skirmishes, which have left scars in southern Europe. Africa is an irresistible force and Europe an immovable object. The next phase of this battle will be at Cyprus where…
A guest post by our very own media master, Nick Small: A historic earthquake in Anatolia As you will all know, an M7.8 earthquake caused massive devastation across Southern Turkiye and Northern Syria on Monday 6/2/23. It ruptured about 100km of the East Anatolian fault at a critically shallow depth of 17.9 km. It was…
Alaska can be a shaky place. Earlier this week, at 10:15pm local time on Wednesday, there was an M8.2 earthquake in the region. It was the largest earthquake on Earth since the M8.3 in Chile in 2015. Let’s award the US the gold olympic medal for earthquaking (after all, the Chilean winner was from the…
Late in 2020, an M6.4 earthquake struck the town of Petrinja in Croatia. It caused extensive damage in the town and in nearby villages, and 7 people died. Even so, the impact was more limited than it might have been because houses here tend to be well build. It came as a surprise: powerful earthquakes…
There is a bit of California here. The fault equals the length of the San Andreas, its shape, its movement, and its earthquakes. Even the ends are alike: where the San Andreas has formed the Salton Sea, its counterpart has embraced the Marmara Sea. Both are places where the crust is being pulled part, and…
Post by Geolurking, based on a repost I have been tasked to revisit something I covered years ago. And update it with a bit of fresh info. The original publish date was 20 Feb 2012. The first thing I need to cover, mainly in order to bring every one up to speed… is the compass rose.…
Part 1 of a Greip Series This week, under the rumblings of Torfajökull, we return to one of our favourite areas within Vatnajökull that is yet to show it’s true hand. Or has it already and is there evidence to support that? Due to some recent activity, Carl has been getting increasingly excited in…
Where there are volcanoes, there are earthquakes. Both are a sign of a broken earth. Volcanoes require vertical movement and earthquakes (by and large) are horizontal: the two are not identical, but to get a volcano you need a vertical path, and to get that you need to move crust sideways. Enter the earthquakes. A…
Sulawesi is the unknown Indonesia. Some may remember it under its Portuguese name of Celebes. It is part of the northern chain of Indonesian islands which runs from Borneo to New Guinea. The island has a disjointed shape, appearing as a connection of peninsulas running in random directions, like an uncoordinated octopus. The four peninsulas…
Humanity has a long history of living on this Earth. During the days and years, our world continuously changed. We grew up in the shadows of the approaching ice ages. We left Africa when the changing sea opened up a road to Asia, and followed an ever-changing coast line to the far East. And throughout…
