Powerful 6.9 magnitude earthquake, strongest since 1975, hits Hawaii's Big Island near erupting volcano

A powerful earthquake measuring magnitude 6.9 has struck just off the Big Island of Hawaii as numerous smaller jolts, including a 5.4 tremor, shook the island in the past hours, amid ongoing volcanic eruption.

The US Geological Survey has upgraded the severity of the earthquake off the Big Island in Hawaii to a 6.9 on the Richter scale, roughly an hour after it was registered. According to the new USGS data, the extremely powerful tremor was registered 16km southwest of Leilani Estates, Hawaii, at a depth of 5.0 km.

The quake struck on the south flank of Kilauea Volcano at 12:33 local time and was followed by several aftershocks, according to the National Weather Service, as eruptions at the volcano continue. No Tsunami warning has been issued.

The tremor was the most powerful of a series of earthquakes that have been rocking the islands over the past days. No Tsunami warnings have been issued after the quake.


Comment: The U.S. Geological Survey said the magnitude-6.9 was the largest Hawaii quake since the 1975 magnitude-7.1 earthquake, which killed two people. The two quakes were centred in almost exactly the same location. See also:

Fears Hawaii's Kilauea volcano will erupt at any moment following 250 earthquakes in the region in 24 hours

A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano

A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano could trigger an eruption, officials have warned. The lava lake at the summit of Kīlauea is one of several persistent on Earth. This image shows how it appeared on the evening of April 11
A series of earthquakes and the collapse of the crater floor at Hawaii's most active volcano could trigger an eruption at any moment, officials have warned.

Lava may burst through the ground east of Kilauea, one of five volcanoes on the US state's largest island, experts say.

The warning follows 250 seismic readings over the past 24 hours, with similar activity recorded prior to previous eruptions in the area.

In mid-April, an observatory issued a volcano activity alert when scientists noticed the Puu Oo vent was inflating and becoming pressurised.

The crater floor of the vent has since collapsed, and an 'intrusion' of lava was sent into a new area of the volcano which spread throughout last night.

Underground magma, which now flows beneath a main road and close to the residential district of Puna, could cause fatalities if it blows.

Ice cauldron in Bárðarbunga The volcano is hidden beneath the ice cap of Vatnajökull glacier.
The monster volcano Bárðarbunga, one of the most active and powerful volcanoes in Iceland and Europe, trembled yesterday afternoon. A sharp 3.9 magnitude earthquake was detected at 16:13 on Sunday afternoon, followed by a handful of smaller quakes.

The volcano has been relatively calm in 2018, with only a handful of 3+ magnitude quakes. The relative calm comes at the heels of relatively high levels of activity in 2016 and 2017. Since the largest earthquake to hit Bárðarbunga at the end of January, a 4.9 magnitude quake.

A 3.9 magnitude quake is considered a significant seismic event, as any quake in an active volcano which is larger than 3 on the Richter scale is considered a powerful quake. Quakes larger than 4 in volcanoes are relatively rare.

According to earthquaketracker.com, Thursday's shakedown was the strongest quake centred in Essex County going back to when records began in 1900

People from all corners of Windsor and Essex County were startled Thursday evening by violent shaking and an explosive sound like a train crashing into the house that was confirmed to be a 3.6 magnitude earthquake centred near Amherstburg.

The quake struck at 8:01 p.m. with an explosive sound and then rumbled on for about 20 seconds.

According to the website earthquaketracker.com, which uses U.S. Geological Survey data, Thursday's shakedown was the strongest quake felt centred in Essex County going back to when records began in 1900.

A strong and damaging M 5.2 earthquake struck near Samsat, Turkey at 00:34 UTC (03:34 local time) on April 24, 2018, causing significant damage and injuring at least 39 people. The earthquake was registered by the USGS as M5.2 and the agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting M5.2 at a depth of 10 km (6.2 miles). According to USGS, the epicenter of the earthquake is 4 km (2.5 miles) NE of Samsat, Turkey which has a population of 9 308 people.

According to Turkish officials, dozens of people were injured after the earthquake. Samsat district governor Sedat Sezik said the earthquake was felt in neighboring cities, adding that search and rescue activities have begun in the province as AFAD teams are reaching the quake site, according to Anadolu news agency.

Turkey's health minister Ahmet Demircan said that 35 were still receiving treatment. The regional governor said the injuries were caused as people fled their homes in panic.

An earthquake has hit southern Iran just 60 miles from the country's Bushehr nuclear power plant.

It hit on Thursday morning and was also felt in Bahrain and other areas around the Persian Gulf.

The US Geological Survey (USGS) said the quake struck at 6.34am GMT, some 60 miles east of the Bushehr nuclear power plant, the only operating nuclear power station in the Islamic Republic.

The USGS put the earthquake's magnitude at 5.5, while Iranian state television, citing officials, described the quake as a magnitude 5.9. Varying magnitudes are common immediately after a temblor.

Government-run TV did not report any damage at the Bushehr plant, which has seen other earthquakes in the past and was built to resist damage from the tremors.

Comment: The area may be prone to tremors and earthquakes, but when we look at the wider picture, there's clearly an uptick in activity on the planet, manifesting itself in a variety of ways:
