Continental Drilling and Northern Sweden...by Melanie Leng

The ICDP Executive Committee in Kiruna, northern SwedenIn early June each year the International Continental scientific Drilling Program (ICDP) committee meets to assess applications for drilling deep holes in the Earth. This year the meeting was held in Kiruna in northern Sweden. Here Melanie Leng explains a bit about ICDP, the UK's geoscience ICDP community, and her trip to Kiruna as the UK's representative on the ICDP Executive Committee.

Gediminas Castle Hill: landslides at a historic site

The Landslide Blog | 27 June, 2017
Gediminas Castle Hill is a historic mound, 40 metres high, on which the Gediminas Tower is located in the city of Vilnius in Lithuania.  This is a key historic site -  Gediminas Tower is the remaining part of the Upper Castle, the origins of which date to 1409.  The mound is natural, being formed of exceptionally weak glacial and lake deposits that have been extensively affected by solifluction, but it has been heavily modified by humans over the centuries.

Protesters invade North Mara Gold Mine in Tanzania.

Sciency Thoughts | 26 June, 2017
About 500 protesters invaded the Acacia Mining operated North Mara Goldmine in the Tarime District of the Mara Region of Tanzania, last week, with 66 being arrested by police. Many of the protesters were armed with spears, machetes, and other traditional weapons, and a number of both police and protesters were injured in clashes at the site. The protesters were demanding compensation for the loss of artisanal mining rights, which were exercised at the site until it was acquired by Barrick Gold (now succeeded by Acacia Mines) in 2002, and to pollution from the site which has allegedly affected local farms.

Asteroid 2017 MF passes the Earth.

Sciency Thoughts | 26 June, 2017
Asteroid 2017 MF passed by the Earth at a distance of 391 500 km (1.01 times the average distance between the Earth and the Moon, 0.26% of the average distance between the Earth and the Sun), slightly before 10.30 pm GMT on Monday 19 June 2017. There was no danger of the asteroid hitting us, though had it done so it would have presented no threat. 2017 MF has an estimated equivalent diameter of 9-28 m (i.e. it is estimated that a spherical object with the same volume would be 9-28 m in diameter), and an object of this size would be expected to explode in an airburst (an explosion caused by superheating from friction with the Earth's atmosphere, which is greater than that caused by simply falling, due to the orbital momentum of the asteroid) in the atmosphere between 33 and 16 km above the ground, with only fragmentary material reaching the Earth's surface.

Imaggeo on Mondays: Breath from the underground

EGU Geolog | 26 June, 2017
The heat seeping from the geothermal area which is part of the Krafla volcanic system in Iceland, 'powers' the steaming vent at Hverir (Hverarönd). The area is well known for its mud pots and sulphuric gas fumaroles, complete with pungent eggy smell.

Team Alaska Day Two

Wooster Geologists | 26 June, 2017
Team Alaska hikes through the woods on a cloudy day to Cedar Lake. At this site they retrieved over 50 increment cores from 25 trees, which will be compared with tree-ring data from Cedar Lake collected in previous years. Lunch included an astounding view of the Pacific Ocean, the misty Chilkat Mountain Range, and some seals! The day ended with another home-cooked meal, followed by some well-earned rest.

Xinmo landslide: an update

The Landslide Blog | 26 June, 2017
Whilst the search for survivors from the Xinmo landslide in Sichuan Province, China continues, the reality is that there can now be almost no prospect of anyone else being found alive. This image, from Xinhua, provides an indication of the scale of the problem facing the recovery teams:

Thirteen dead following explosion at illegal coal mine in Colombia.

Sciency Thoughts | 26 June, 2017
Thirteen mineworkers have been confirmed dead following an underground explosion at an illegal coal mine near the town of Cucunubá in Ubaté Province, Colombia, on Friday 23 June 2017. The bodies of eleven of the men were confirmed dead shortly after the explosion, with the remaining two, who it was initially hopes might have survived, being found the next day

Brachylophus gau: A new species of South Pacific Iguana from Gau Island, Fiji.

Sciency Thoughts | 25 June, 2017
Three living and one extinct species of South Pacific Iguana, Brachylophus spp., are known from the islands of Fiji, as well as a single species of a second genus Lapitiguana, a much larger, but also now extinct, Lizard. These Iguana's are thought to have lived in isolation in the island group for around 40 million years, with their closest living relatives found in the deserts of the southwestern United States. Each species of South Pacific Iguana is recorded only from a single island, but several other islands of Fiji are known to host Iguanas, suggesting that either some of these species have greater ranges than has previously been recorded, or that there are undiscovered species of Iguana in the islands.

Sichuan landslide feared to have killed over 100 people.

Sciency Thoughts | 25 June, 2017
Over a hundred people are feared to have died following a landslide in a remote mountain village in Mao County in Sichuan Province, China, on Saturday 24 June 2017. The landslide struck the village of Xinmo at about 6.00 am local time, sweeping away all of the about forty homes in the village and damming a nearby river. So far only three survivors have been found, a couple and their two month old baby, all of whom are being treated in a nearby hospital, while 25 bodies have been recovered and 93 people are missing. A further 15 residents of the village have been confirmed safe as they were staying outside the community when the landslip occurred. Over three thousand rescue workers, assisted by specially trained dogs, are involved in the ongoing search, though there is thought to be little hope of finding any more survivors.

Team Alaska Day One

Wooster Geologists | 25 June, 2017
Day one involved team Alaska hiking the East Glacier Trail led by Brian Buma, a forest ecologist from the University of Alaska Southeast. Their goal was to sample yellow-cedar trees at high elevation sites and understand how the dynamics of the forest relate to climate change. The trip was off the beaten path after 2 miles and continued for another 6 miles through a steep, muddy, dense understory. The group only stopped to eat lunch, but it was a sublime day with amazing company. Upwards of 50 samples were collected from a boggy environment, known as a "muskeg". After a very long but exciting day the group headed down the trail for home-cooked fish tacos. Yum!
