Coastal elevation in California. Coastal zones, which are defined to be those with elevations less than 10 m, are shown in red. Segments of the coast with elevations higher than 10 m are colored by a yellow gradient.
A majority of the world population lives on low lying lands near the sea, some of which are predicted to submerge by the end of the 21st century due to rising sea levels.

The most relevant quantity for assessing the impacts of sea-level change on these communities is the relative sea-level rise — the elevation change between the Earth's surface height and sea surface height. For an observer standing on the coastland, relative sea-level rise is the net change in the sea level, which also includes the rise and fall of the land beneath observer's feet.

Now, using precise measurements from state-of-the-art satellite-based interferometric synthetic aperture radar (InSAR) that can detect the land surface rise and fall with millimeter accuracy, an Arizona State University research team has, for the first time, tracked the entire California coast's vertical land motion.

The Red Sea and the Gulf of Aden emerged as the result of a deep geological process that has been going on for the last 30 million years with Arabia moving away from Africa. But even these waters could soon merge into a new, yet-to-be-named ocean, as the world's hottest continent splits apart.

Something is going on underneath the African continent. It has been known for some time that the three tectonic plates, Nubian, Somali and Arabian, that lie beneath the continent's Afar region, have been very slowly peeling apart from each other. Now researchers are able to use satellite images and measurements to study the process more precisely and predict how a new ocean will soon flood the region, according to NBC News.

A sinkhole near the intersection of Ramond Road and Chicopee Street has caused traffic snarls in the area.

The hole first appeared the morning of July 14 when the paved road gave way and a parked car sank about halfway into the hole.

No one was injured in the surprise incident, said Erin Hastings, executive director of Westcomm Regional Dispatch.

It is not clear what caused the sinkhole to open, but Hastings said dispatch was made aware of a nearby water main break that may have had something to do with it. The water main was repaired by 1 p.m.

A parked car fell into a sinkhole on 2nd Street.
A parked SUV was swallowed by a massive sinkhole in the East Village early Sunday when the road caved in beneath it, police said.

The silver Toyota SUV was on East Second Street near Avenue A around 2:30 a.m. Sunday when its front half fell into the newly-formed pit, cops said.

Photos showed the empty, four-door vehicle straddling the edge of the crater — with FDNY on the scene.

Con Edison was notified about the incident, police said.

Slade Lake disappears overnight in Canada Nova Scotia in June 2020.
Picture in your mind's eye a bathtub that's a kilometre-and-a-half long by 200-metres wide. Then pull the plug. In essence, that is what's happened this spring to Slade Lake.

Two-and-a-half kilometres southwest of Oxford, Cumberland County, the large lake has been drained of its water by underground geological activity.

"The most obvious culprit for this is the water just disappeared down some of the sinkholes at the bottom of the lake," said Amy Tizzard, regional geologist for the Department of Energy and Mines.

"It could be that some gypsum dissolved (below the lake) or sediment or vegetation gave way... we can't really tell because we can't see to the bottom of it."

Comment: While the area may be vulnerable to erosion the question of what's driving the sudden increase, as well as the disappearing lakes, rivers, and even waterfalls...

Weakening of Earth's magnetic field probed

A simulation of the Earth’s magnetic field.
Geophysicists have been puzzling over a gradual weakening of the Earth's magnetic field in an area stretching from Africa to South America, which has resulted in technical disturbances in satellites orbiting Earth.

Scientists have resorted to data from the European Space Agency's (ESA) Swarm constellation to probe the disturbing weakening of Earth's magnetic field in the area known as the "South Atlantic Anomaly".

Jurgen Matzka, from the German Research Centre for Geosciences, and a team of experts from the Swarm Data, Innovation and Science Cluster (DISC) have been using data from ESA's Swarm satellite constellation to identify and measure the different magnetic signals that comprise Earth's magnetic field.
"The new, eastern minimum of the South Atlantic Anomaly has appeared over the last decade and in recent years is developing vigorously. We are very lucky to have the Swarm satellites in orbit to investigate the development of the South Atlantic Anomaly. The challenge now is to understand the processes in Earth's core driving these changes," said Matzka.

Eight houses were swept into the sea by the powerful landslide in northern Norway
With a small portion of Norway's coastal range slipping into the sea, it does fit perfectly the time line intensification of our four gas giants forming a square in one quadrant of our solar system not seen since 79A.D during an intensifying Grand Solar Minimum.

My question: Does this signal the beginning of more intense global liquefaction events? Let me know what you think about the information presented, does it show a trend?

Geysers may be signalling magma intrusion under Yellowstone

Steamboat Geyser

Steamboat Geyser erupts on 4 June 2018. Scientists examined how deformation and hydrothermal activity in the northern rim area of the Yellowstone caldera might be linked to magmatic intrusions kilometers beneath the surface.
Steamboat Geyser in Yellowstone National Park is an enigma. It is the tallest currently active geyser in the world, sometimes blasting superheated water over 90 meters (300 feet) into the air. Yet unlike the more famous Old Faithful, Steamboat Geyser runs on its own rhythm. Sometimes the geyser is quiet for decades and then suddenly bursts back to life. It is a mystery exactly why Steamboat has such behavior. After a new period of activity started in 2018, we might have more clues about what drives these steam-and-water explosions.

Yellowstone caldera is a geologic wonderland. It is the source of three of the largest explosive eruptions in the past 3 million years. The caldera itself covers over 1,500 square kilometers (580 square miles) in the northeast corner of Wyoming. As Charles Wicks from the U.S. Geological Survey (USGS) puts it, "Yellowstone's roots seem to extend all the way to the core-mantle boundary. In that dimension, it's a magmatic system of continental scale."

The Yellowstone caldera is packed with geothermal features like geysers, hot springs, mud pots, and geothermal pools. This hydrothermal activity is driven by the vast reservoirs of heat beneath the Yellowstone area, most of which comes from the magma found many kilometers underneath the caldera. All this heat and water mean the land surface at Yellowstone rises and falls frequently, meaning Yellowstone is best described as a "restless caldera."

Mother, child rescued after sinkhole swallows their car in Nuevo Laredo, Mexico

Outdated infrastructure was blamed for this sinkhole in Nuevo Laredo.

Outdated infrastructure was blamed for this sinkhole in Nuevo Laredo.
A mother and daughter were rescued unharmed after their car was swallowed by a sinkhole caused by intense rains in Nuevo Laredo, Tamaulipas, early Tuesday morning.

The sinkhole opened up beneath their 2010 Volkswagen Jetta at around 5:30 a.m., but despite the spectacular nature of the incident, the car remained right-side-up and the mother and her young daughter were not injured.

Firefighters and Civil Protection rescuers arrived on the scene to find the two on top of their car, which was surrounded by water and mud at the bottom of the hole, which was more than five meters below street level.

Sinkhole opens up and swallows floodwater in Bomet County, Kenya

sinkhole
Resident of Bomet County were treated to a shocking show of sink-hole that swallowed vegetation around it.

A sinkhole is a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. With area being swampy from the video, underground water current may have forced the water and vegetation to the inside.

From the details in the video, this geographical phenomenon may have been caused by the heavy rainfall that continue to pour across the country. The area in the video also seem to be swampy and this may explain why the vegetation around it were 'disappearing' underground.

Sinkholes can be natural or man-made. They are caused by either erosion or underground water. The video from Bomet strongly suggest that the sinkhole may have been caused by underground water.
