While New York City is rarely thought of as a hotspot for seismic activity, scientists have determined the Big Apple is overdue for a devastating earthquake that could effectively level the heart of the city.
The U.S. Geological Survey notes there are nine fault lines running through parts of the city, the largest of which begins in New Jersey and passes Central Park on its way to Roosevelt Island. Others run immediately adjacent to the Empire State Building, Wall Street, and the Barclays Center, home of the NBA’s Brooklyn Nets and NHL’s New York Islanders.
According to a new report released by the New York City Consortium for Earthquake Loss Mitigation, even a 5.0-magnitude earthquake—strong, but not considered “major” on the Richter scale—could cause $39 billion in damage and create more than 30 million tons of rubble. A quake of that magnitude, based on the geological record, occurs every 100 years, but the last was in 1884.
A stronger, 7.0-magnitude quake, which occurs far less frequently, would cause more than 6,000 older buildings, most of which do not have reinforced masonry to topple. That is also due to the density of tall buildings in the city that aren’t built to withstand seismic stresses.
A very strong and shallow earthquake registered by the USGS as M7.5 hit Papua New Guinea at 17:44 UTC on February 25, 2018 (03:44 local time, February 26). The agency is reporting a depth of 35 km (21.7 miles). EMSC is reporting M7.5 at a depth of 30 km (18.6 miles). This earthquake is expected to have a high humanitarian impact based on the magnitude and the affected population and their vulnerability.
According to the USGS, the epicenter was located 33.1 km (20.5 miles) SW Tari (population 8 186), 98.5 km (61.2 miles) W of Mendi (population 26 252) and 163.4 km (101.5 miles) E of Kiunga (population 11 536), Papua New Guinea.
There are 670 000 people living within 100 km (62 miles) and 12 000 within 10 km.
Some 10 000 people are estimated to have felt severe shaking, 356 000 very strong, 660 000 strong and 1 423 000 moderate.
The USGS issued a yellow alert for shaking-related fatalities and economic losses. Some casualties and damage are possible and the impact should be relatively localized. Past yellow alerts have required a local or regional level response.
A potent earthquake shook southern Mexico on Friday, a prolonged rumble that rocked buildings across Mexico City.
Originally reported as a 7.5 magnitude, the quake was later reported as a 7.2 by the U.S. Geological Survey, said an article Friday night in USA Today.
According to the Reuters news service, the epicenter was close to the Pacific coast in the southern state of Oaxaca, and had a depth of 26.7 miles (43 km), based on data from the U.S. Geological Survey. The area is already reeling from a September earthquake’s impacts.
In Oaxaca, Gov. Alejandro Murat said via Twitter that damage was being evaluated, but there were so far no reports of deaths.
A 6.4-magnitude earthquake struck the east coast of Taiwan, causing a hotel and several other buildings to collapse. At least two people were killed and more than 200 others injured.
The epicenter of the quake was reportedly 10km deep, some 22km east-northeast of Hualien City, the US Geological Service (USGS) reported. The initial 6.4 quake, which struck at 11:50pm local time, was followed by a number of aftershocks, with at least four measuring five points and higher on the Richter scale, the USGS data shows.
At least five buildings collapsed, China Global Television Network (CGTN) reported. “Two people were unfortunately killed,” Taiwan’s Premier William Lai told an emergency government meeting.
Images posted online appear to show the first floor of the Marshal Hotel in Hualien severely damaged, with parts of the building crumbling onto the sidewalk. Multiple injuries have been reported and rescue workers have been deployed to the scene. According to the Central Disaster Response Center, at least three people remain trapped underneath the debris in Marshal Hotel.
A strong earthquake registered by the CSN Chile as M6.3 hit northern Chile at 01:06 UTC on January 21, 2018 (22:06 local time, January 20). The agency is reporting a depth of 105.3 km (65.4 miles). USGS is reporting M6.3 at a depth of 110.8 km (68.8 miles); EMSC M6.4 at 110 km. The quake was preceded by M3.0 at 22:45 UTC, January 20.
According to the USGS, the epicenter was located 76.6 km (47.6 miles) S of Putre (population 0), 85.2 km (52.9 miles) ESE of Arica (population 185 999), Chile and 117.8 km (73.2 miles) SE of Tacna (population 280 098), Peru.
There are 230 000 people living within 100 km (62 miles) and less than 1 000 within 10 km (6.2 miles).
According to the USGS, some 128 000 people are estimated to have felt moderate shaking.
However, CSN Chile reports very strong shaking in Arica and in the village of Codpa. Strong shaking was reported in Cuya, Pocon Chile and Putre.
A very strong and shallow earthquake registered by the USGS as M7.6 hit north of Honduras at 02:51 UTC on January 10, 2018 (20:51 local time, January 9). The agency is reporting a depth of 10 km (6.2 miles). EMSC reported M7.6 at a depth of 15 km (9 miles). Minor sea level fluctuations have been observed and may continue during the next couple of hours.
According to the USGS, the epicenter was located 201.9 km (125.5 miles) NNE of Barra Patuca (population 2 758) and 245.2 km (152.4 miles) N of Puerto Lempira (population 4 856), Honduras.
There are no people living within 100 km (62 miles).
Some 58 000 people are estimated to have felt moderate shaking and 3 318 000 light.
Minor tsunami waves have been observed (up to 30 cm / 0.98 feet) and may continue over the next few hours, PTWC said 04:48 UTC.
Ths USGS issued a green alert for shaking-related fatalities and economic losses. There is a low likelihood of casualties and damage.
Just when it seemed like things may be settling down, two very unusual earthquakes have hit the west coast within the past couple of days. A 4.4 magnitude quake struck Berkeley, California just prior to 3 AM on Thursday morning, and a 3.9 magnitude earthquake hit Mount St. Helens in Washington state on Wednesday. Overall, there have been 68 earthquakes in the vicinity of Mount St. Helens since New Year’s Day, and there have been a total of 629 earthquakes in the state of California within the last 30 days. Could it be possible that all of this activity is leading up to a historic seismic disaster on the west coast?
Two tremors detected in North Korea yesterday were likely to be aftershocks from the hermit nation’s reckless nuclear test in early September, a US Geological Survey official confirmed.
The mild 2.9 and 2.4 magnitude aftershocks were confirmed as “tectonic” in origin by the Vienna-based Comprehensive Nuclear-Test-Ban Treaty executive secretary Lassina Zerbo.
The USGS official claimed the tremors originated near the Punggye-ri nuclear test site – the location where North Korea carried out its largest nuclear test to date on September 3.
The official said: “They’re probably relaxation events from the sixth nuclear test. When you have a large nuclear test, it moves the Earth’s crust around the area, and it takes a while for it to fully subside.
“We’ve had a few of them since the sixth nuclear test.”
