Earthquakes
To top of today's series of earthquakes, a quake measuring 4.5 occurred at the mother of all volcanoes in Iceland, Katla tonight at around 10.30 pm. Another earthquake measuring 3.2 occurred a little later. Both eruptions were felt in nearby areas.
A specialist on duty tonight at the Iceland Met Office says that the earthquakes are nothing to worry about. It's quite usual to have a few tremors when the ice cap melts in summer.
There is no connection between the earthquake in Katla tonight and the series of earthquakes occuring in Reykjanes today.
According to the Iceland Met Office, over 500 earthquakes have been measured in the swarm which began yesterday morning at 7 am. Three earthquakes were clearly felt in Reykjavik, especially the one at 13:55 which measured 4.1.
Geophysicist Páll Einarsson said speaking to today's Morgunblaðið that the earthquakes are at the point where the tectonic plates meet. He said that although earthquakes in Reykjanes are common, the swarm yesterday was one of the biggest that they've measured in a few years.
An earthquake of magnitude 6.1 struck in the Pacific Ocean, off the coast of Japan, this morning.
The shaker - which is classed as "strong" - was near the island of Okinawa, which has a population of more than 1.4million.
Almost 16,000 people were killed by an earthquake off Japan's coast in 2011.
The under-sea tremor - which has a similar depth to today's quake - caused a tsunami, which led to the Fukushima Daiichi nuclear disaster.

The 6.7-magnitude tremor also left hundreds more injured in the Turkish resort of Bodrum, about 20 kilometres (12 miles) across the sea from Kos.
"Given the amount of people outside at the time, having only two victims is a miracle," deputy Kos mayor David Yerasklis told Kathimerini daily.
The undersea quake struck at 1:31 am Friday (2231 GMT Thursday) between Kos and Bodrum.
At the time, tourists in both places were out enjoying the nightlife.
On Kos, a wall collapsed on people in the courtyard of a nightclub, killing a 22-year-old Swede and a 39-year-old Turk.
Greek authorities confirmed the victims of the 6.5-magnitude quake, both men, were from Turkey and Sweden.
The 6.5-magnitude quake struck at around 1am local time on Friday morning, rattling the Greek holiday resort of Kos, damaging buildings and the main port.
Chief of National Disaster Mitigation Agency (BNPB) Sutopo Purwo Nugroho said here that following the eruption, the volcano spewed ashes 3.5 thousand meters into the air, while discharging lava 1 thousand meters to the mountains southern region.
Earlier on Wednesday, the volcano spewed ashes 1.5 thousand meters into the air and causing six tremors, 20 volcanic earthquakes, and one tectonic earthquake.
In Wednesdays eruption, since 12 p.m. local time, the volcano spewed ashes 700 meters into the air, while releasing lava 1 thousand meters to the east and the southeast.
The quake struck at an estimated depth of 10km some 12km off the Turkish resort city of Bodrum in Mugla Province, the European Mediterranean Seismological Center reported. It was followed by several less powerful aftershocks.
The tremors caused a tsunami wave, apparently large enough to reach some hotels located on the coastline, as photos shared online indicated.

Update (21 July):
RT reports that two people have been killed and dozens more injured after a 6.7 magnitude earthquake struck in the Mediterranean Sea early Friday morning. The quake hit close to Turkey and the Greek island of Kos, triggering a mini tsunami which flooded some areas.

An earthquake with an initial magnitude of 5.8 hit northeast of Tokyo on Japan's main island of Honshu on July 20, 2017.
The 5.8-magnitude quake hit at 9:11 am (0011 GMT) off Fukushima prefecture in the Pacific Ocean with the epicentre located 34 kilometres (21 miles) under the sea, according to the US Geological Survey. Japan's meteorological agency said there was no risk of tsunami from the earthquake.
"We have found no (new) abnormality so far" at the Fukushima Daiichi plant, said a spokesman at Tokyo Electric Power Co., the operator.
The epicenter of the shock was located 9.3 mi N of W. Yellowstone, MT.This earthquake is part of an ongoing sequence of earthquakes that began on June 12, 2017 and included a magnitude 4.4 event on June 15, 2017, 9.0 mi NNE of W. Yellowstone, MT.
Today's M 3.6 earthquake was reported felt in Yellowstone National Park and in West Yellowstone, MT.
It was followed by numerous smaller earthquakes, the largest of which had magnitudes of 2.8 and 2.9.
The total number of located earthquakes in the current sequence has now exceeded 1200.
The epicenter of the earthquake was roughly 10 km (6 miles) below the earth's surface.
The 5.9-magnitude earthquake has occurred at 12:16:25 / 12:16 pm (local time epicenter).
A tsunami warning has not been issued (Does not indicate if a tsunami actually did or will exist).
