Japan quake on June 18, 2019.
A tsunami warning has been issued after a magnitude 6.8 earthquake struck close to the coast of Japan.

There were no immediate reports of casualties, but the country's Meteorological Agency issued a warning for a 0.2 - 1 metre tsunami along the northwest coast of the main island of Honshu.

The quake struck around 30 miles southwest of the city of Sakata at 10.22pm on Tuesday, the agency reported, with the coastal areas of Yamagata and Niigata prefectures and the Noto area in Ishikawa Prefecture receiving tsunami advisories.

It said the quake's epicentre was fairly shallow, about six miles below the sea's surface.

Shallow quakes tend to cause more damage on the Earth's surface, but the agency said the expected "fluctuation" of waves was unlikely to cause damage.

Two strong earthquakes shook the southwestern Chinese province of Sichuan on Monday, killing at least one person in a part of the country frequently affected by strong tremors.

The first magnitude 5.9 quake was followed around 30 minutes later by one registering 5.2, both at a depth of 10 km (six miles) and centered near Changning county, according to the United States Geological Survey.

Chinese state media said shaking was felt in major cities in the region, including in the Sichuan provincial capital Chengdu and the metropolis of Chongqing.

The Ministry of Civil Defence and Emergency Management has cleared New Zealand of a second tsunami threat following another earthquake near the Kermadec Islands.

The region was rocked by a second earthquake a short time ago which registered magnitude 6.6 following a magnitude 7.0 at 10.55am.

The second earthquake struck shortly before 5.30pm.

"There is no tsunami threat to New Zealand following the M6.6 Kermadec Islands region earthquake," MCDEM said on Twitter.

A magnitude 6.1 earthquake struck on Sunday centred 97km north-east of Ohonua, on the Pacific island of Tonga, the US Geological Survey reported.

The quake hit at 2156 GMT on Saturday with an epicentre depth of 10km, the US global quake monitor said.

The Pacific Tsunami Warning Centre issued no alerts, and there were no immediate reports of damage or casualties.

The reported epicentre lies within the so-called Pacific Ring of Fire, an area of regular seismic activity.

In February 2018, a 7.5 magnitude earthquake in Papua New Guinea killed 150 people and destroyed hundreds of buildings.

The Ministry of Civil Defence Management and GNS Science in New Zealand are currently investigating the possibility of a tsunami hitting the country following the colossal quake.

The earthquake hit the Kermadec Islands, approximately 620 miles northeast of New Zealand. The colossal quake hit at 11.54pm BST (11.54am local time) according to the USGS.

The New Zealand Civil Defense released a statement saying: "We are assessing whether the M7.4 Kermadec Islands region earthquake poses any tsunami threat to New Zealand.

"If a tsunami has been generated it is not likely to arrive in New Zealand for at least two hours."

The USGS reported that the quake had a depth of 21 miles.

The epicentre was around 93 miles (150km) from L'Esperance rock halfway between New Zealand and Tongo.

A powerful magnitude-6.5 earthquake has shaken Chile's Pacific coast but there have been no immediate reports of major damages or injuries.

The US Geological Survey said the quake struck at 7:19 pm local time at a depth of 10 kilometres and its epicentre was 79.9 kilometres west of Coquimbo, Chile.

Chilean authorities said the quake was centred under the ocean and no tsunami warning issued.

Chile is located in the so-called "Ring of Fire," which makes it one of the most seismic countries in the world.

An 8.8-magnitude earthquake and ensuing tsunami in 2010 killed 525 people and left 26 missing.

A 4.0 magnitude earthquake struck near Cleveland, Ohio, on Monday morning.
An earthquake was recorded in northeastern Ohio on Monday morning. The preliminary magnitude 4.0 earthquake was centered just north of Eastlake, Ohio, according to the United States Geological Survey (USGS).

There were no reports immediately of damage. A magnitude 4 earthquake can cause light to moderate damage.

The USGS is collecting responses from people who felt the tremors. Over 8,000 people reported feeling the earthquake so far. The majority of reports rate the intensity as weak to light, USGS reports.

The event occurred in a region that is not typically associated with high seismic activity, and many resident contacted local emergency officials after the shake. The City of Mentor said that the dispatch is "overwhelmed with 911 calls," but that they "are waiting for the experts to affirm what was probably an earthquake here."

"Please don't cal 911 unless you are having an emergency," the City of Mentor said in a tweet.

The Ohio Department of Transportation (ODOT) captured the earthquake on multiple traffic cams.

California earthquakes
The unusual shaking on the west coast continues to intensify. As you can see from this map, 240 earthquakes have struck the states of California and Nevada over the last 24 hours. Yes, the west coast gets hit by quakes every day, but this is definitely an unusually high number. Fortunately, most of the earthquakes have been very small, but a couple of them were greater than magnitude 3.0. The following comes from the Los Angeles Times...
A magnitude 3.3 earthquake was felt in parts of Southern California on Sunday afternoon, one in a series of quakes to hit the Riverside County area.

The latest quake occurred at 4:36 p.m. and was centered on Glen Avon, south of Fontana. The seismic activity continued into Monday morning with dozens of new small quakes.

According to the U.S. Geological Survey, the quakes were felt across swaths of the Inland Empire, a region that has had hundreds of small quakes over the weekend, including one that registered a magnitude of 3.1.
