Deux géologues annoncent que le ralentissement de la rotation terrestre entraînera une vague de grands séismes en 2018
En effet, tous les trente-deux ans environ, le nombre de séismes majeurs connaît un pic dû au ralentissement de la rotation terrestre. Ce ralentissement oblige par ailleurs à corriger d'une seconde par an l'horloge atomique qui définit le temps universel.
Existe-il un lien avec le fait que Vénus a aussi ralenti sa rotation ? Ce lien serait-il d'origine « cosmique » ?
Ce ralentissement de la rotation terrestre pourrait aussi être connecté avec l'augmentation constante du nombre de dolines (ou sinkholes en anglais) qui s'ouvrent un peu partout dans le monde. Serait-il aussi en lien avec les hécatombes massives d'animaux et autres signes des temps ?
Rebecca Bendick a précisé dans le journal Science, que la Terre tourne à 460 mètres par seconde à l'équateur, et Peter Molnar, un autre géologue de l'université du Colorado, a avancé que « même un léger décalage entre la croûte terrestre, le manteau et le noyau en fusion de notre planète pourrait déclencher des forces causant ces séismes ».

Palu, Indonesia: Indonesian authorities say at least three people have been killed and four injured after a powerful earthquake struck near the popular tourist island of Bali on Thursday.
Sutopo Purwo Nugroho, a spokesman for Indonesia's disaster agency BNPB, wrote on Twitter that several houses were also damaged in the magnitude 6.0 earthquake that shook Bali and East Java.
The country is still reeling from an earthquake and tsunami last month that killed at least 2045 people, with up to 5000 still missing.
The International Monetary Fund and its sister lending organisation, the World Bank, are holding annual meetings attended by international delegations on Bali until Sunday.
Also on Thursday morning a magnitude 7.0 earthquake struck remote New Britain island in Papua New Guinea, the United States Geological Survey says.
It was centred 124 kilometres east of Kimbe and about 200 kilometres south-west of the town of Rabaul at a depth of almost 40 kilometres, just before 7am local time (8am AEDT) on Thursday.
Police officers had not yet been able to contact villages close to the epicentre.
The Pacific Tsunami Warning Centre said in a mid-morning release that there was no longer a tsunami threat from the quake.
It said earlier that a tsunami threat existed for parts of the Pacific located closer to the earthquake, adding that tsunami waves were forecast to be under 30 centimetres for the coasts of Papua New Guinea and the nearby Solomon Islands.
Pacific Tsunami Warning Centre oceanographer David Walsh had said any tsunami from the earthquake would only affect areas immediately around the epicentre.
Areas further away were unlikely to be affected because the earthquake was not "terribly large" and many areas were shielded by land masses and islands, he said.
Scientists don't have any tide gauges close to the where the earthquake happened.
Australia's Tsunami Warning Centre said its coastlines were not at risk.
The PNG quake was initially recorded with a magnitude of 7.3 but was downgraded. It was followed by aftershocks of magnitude 5.7 and 5.9.
Just more than an hour later, a magnitude 6.3 quake hit further north-east on the island.
In March, a 6.6 magnitude quake struck nearby and no casualties or damage were reported.
Papua New Guinea, one of the world's poorest countries, sits on the geologically active Pacific Ring of Fire and is still recovering from a 7.5 quake that hit 900km to the west in February, killing at least 100 people.
The magnitude 6 earthquake struck off the Indonesian islands of Java and Bali on Thursday, the US Geological Survey (USGS) said, damaging some buildings in East Java while causing panic among residents.
The quake, located in the Bali Sea, also shook buildings on the resort island and some residents briefly left their homes in Bali's capital, Denpasar.
The three deaths occurred after buildings collapsed while people were sleeping, Sutopo Purwo Nugroho said.
The USGS put the epicentre as 40 kilometres north-east of Sumberanyar on nearby Java island.
The annual meetings of the International Monetary Fund and World Bank is hosting more than 19,000 delegates and other guests, including ministers and some leaders.
A magnitude 6.3 earthquake also struck in a remote region south of the Kuril islands off eastern Russia, the USGS said.
No immediate tsunami warnings issued. The quake struck 177 kilometres south of Severo-Kurilsk at a depth of 33 kilometres on Thursday morning. There were no immediate reports of damage or casualties.
