Earthquakes around the world

▪ Water levels in Florida wells changed briefly after Tuesday's earthquake in the Gulf of Alaska.
▪ Seismic waves traveling through the earth often cause groundwater changes after earthquakes.

Something Shocking Happened in Florida After the Alaska Earthquake: Well Water Levels Changed Jan. 24, 2018
https://weather.com/news/news/2018-01-24-alaska-earthquake-florida-wells-shaking

Tuesday's 7.9 magnitude earthquake in the Gulf of Alaska sent vibrations through the earth that caused water to rise and fall in wells in Florida, thousands of miles away.

Sensors near Fort Lauderdale and Madison, near the Georgia border, showed a minor change in water levels after the earthquake, according to the United States Geological Survey (USGS).

A water level rise from 41.59 feet to 41.77 feet was recorded at the well near Madison before it returned to normal. At the well near Fort Lauderdale, the water level fell from 1.42 feet to 1.31 feet.

Why did water levels in these wells some 3,800 miles away from the earthquake's epicenter change?

Vibrations that move through the earth called seismic waves are the culprit. Seismic waves are depicted by the upward and downward lines on seismographs used to detect earthquakes around the world.

"Water levels in wells respond to the seismic-wave induced expansion and contraction of the aquifer tapped by the well, in turn causing step or oscillatory fluid-pressure changes," the USGS says.

The changes in groundwater levels are often seen hundreds, or even thousands, of miles away from an earthquake's epicenter.

After an 8.5 magnitude earthquake near Alaska in 1964 water level changes were reported at 716 wells in the United States, according to the USGS.

Occasionally, changes can be extreme.

A 5.2 magnitude northwest Pennsylvania temblor in 1998 rendered dry about 120 wells for local homes for about three months.

The Denali, Alaska, 7.9 magnitude earthquake of 2002 caused a well in Wisconsin to rise 2 feet.

The US Geological Survey reported of a strong 6.1 magnitude earthquake striking Taiwan's east coast 17 km (10 miles) northeast of Hua-lien.

The agency stated the quake took place at a depth of 7.8 km.

However, according to information from the China Earthquake Networks Center, the tremors were of lesser magnitude — about 5.6.

No tsunami warning has been issued so far, as well as no information about possible casualties or damages reported.

The number of injured in a powerful earthquake in eastern Taiwan on Tuesday has increased from 114 to 188 people, China's CGTN television reported.

Number of Injured in Taiwan Quake Rises to 188

The US Geological Survey earlier reported that a 6.4-magnitude earthquake occurred about 22 kilometers (14 miles) northeast of the city of Hualien at the depth of 11 kilometers at about 23:50 local time (15:50 GMT).

According to CGTN, underground shocks caused serious damages to infrastructure, with at least five buildings partially or completely destroyed in Hualien, including a hotel. The latest reports indicate that a large number of guests were trapped in the hotel building, some 116 guests have already been evacuated.

The tremors also caused disruptions in the transport and energy supply systems, with more than 560 houses left without electricity. The search and rescue operation, involving military personnel, firefighters, rescuers, doctors and specially trained police dogs, continues, the CGTN reported.

The earthquake is the second one in the area in several days, the previous 6.6-magnitude quake has struck the east coast just adozen miles (17km) off Hualien.
 
The new tremors were registered after the earthquake on Tuesday killed six and injured up to 256 people.

The US Geological Survey reported that the 5.7 magnitude quake hit off Taiwan's coast. The tremors were registered at 11:21 PM on Wednesday in the water area near the Hualien County, where the previous quake occurred. The epicenter of the earthquake was at a depth of 12 kilometers, according to China Earthquake Networks Center (CENC).

The previous quake hit the northeast of the island on Tuesday, resulting in six people being killed, 260 injuries and 67 going missing. The epicenter of the deadly quake was at a depth of 11 kilometers.

A well known area to have strong earthquakes, and again with the same day, at least it was in another month, though... the 1995 Colima–Jalisco earthquake of 8.0
 
minutes ago another earthquake was felt in Mexico City strong but not rough, so far ...did not heard anything falling this time, do not know more ... hope everyone is fine ...

Dutchsinse has put this video up, discussing this event:

It goes for over an hour, but the nitty gritty will be near the beginning of the video, and he shows some news vid from the area. I hope all the Mexican crew are OK, God Bless you guys! It was apparently up in the mountains and no large towns nearby, but the small villages would certainly have been rocking!

I hope so too that everybody is fine. The pacific ring of fire is indeed very active in the last months.
