Another quick video of the liquid earth. This is one of the coolest things I have ever seen on a job. The dirt was literally moving in waves as you can see. Be sure to watch in HD for the best picture.
What this is, is someone filled in an old in ground swimming pool with clay and didn't punch a hole in the bottom to let any surface or rain water escape, so over time the clay became extremely saturated. When I drove the mini excavator over it the clay began to "pump" or liquify and this is what happened. I have seen soil liquefaction before but never to this extreme.

In geology, liquefaction refers to the process by which saturated, unconsolidated sediments are transformed into a substance that acts like a liquid.
Earthquakes can cause soil liquefaction where loosely packed, water-logged sediments come loose from the intense shaking of the earthquake.

H. Bolton Seed Medal Lecture
Evaluation of Soil Liquefaction – How Far Have We Come in
the Past 30 Years?
Professor H. Bolton Seed and his colleagues developed a simplified method to evaluate cyclic liquefaction. Since then, significant developments have occurred in the past 30 years. This lecture will present a brief overview of the major developments to evaluate soil liquefaction based on in-situ tests, with an emphasis on the seismic cone penetration test (SCPT). The presentation will attempt to link the traditional simplified empirical methods with a more theoretical approach based on Critical State Soil Mechanics in an effort to present a unified approach that covers both cyclic and flow liquefaction. Delivered annually by the recipient of the H. Bolton Seed Medal for outstanding contributions to teaching, research, or practice in geotechnical engineering.
Presented by Peter K. Robertson, Ph.D., P.Eng, Professor Emeritus,
University of Alberta, Technical Advisor, Gregg Drilling & Testing Inc.
Dr. Robertson may be best known for work with Cone Penetration testing and his soil behavior type classification systems which has become an industry standard used by engineers every day all over the world. He also is a recognized expert in liquefaction and his CPT-based triggering evaluation methodology is widely used.
Dr. Roberston held the position of Professor at the University of Alberta at Edmonton, where he taught courses, performed research and led research teams, and held important administrative posts for seventeen years. During that period he instructed hundreds of students and supervised many MS and PhD research projects.
He has authored three books, published 86 peer-reviewed papers in the geotechnical literature, and written over one hundred additional papers and reports for conferences and symposia proceedings. Sharing his experiences, research findings and insight is clearly one of the hallmarks of his career.
He has received several prestigious awards, including three R.M. Quigley Awards from the Canadian Geotechnical Society for paper of the year published in the Canadian Geotechnical Journal.

Soil liquefaction
Soil liquefaction describes a phenomenon whereby a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.
In soil mechanics the term "liquefied" was first used by Hazen in reference to the 1918 failure of the Calaveras Dam in California. He described the mechanism of flow liquefaction of the embankment dam as follows:
The phenomenon is most often observed in saturated, loose (low density or uncompacted), sandy soils. This is because a loose sand has a tendency to compress when a load is applied; dense sands by contrast tend to expand in volume or 'dilate'. If the soil is saturated by water, a condition that often exists when the soil is below the ground water table or sea level, then water fills the gaps between soil grains ('pore spaces'). In response to the soil compressing, this water increases in pressure and attempts to flow out from the soil to zones of low pressure (usually upward towards the ground surface). However, if the loading is rapidly applied and large enough, or is repeated many times (e.g. earthquake shaking, storm wave loading) such that it does not flow out in time before the next cycle of load is applied, the water pressures may build to an extent where they exceed the contact stresses between the grains of soil that keep them in contact with each other. These contacts between grains are the means by which the weight from buildings and overlying soil layers are transferred from the ground surface to layers of soil or rock at greater depths. This loss of soil structure causes it to lose all of its strength (the ability to transfer shear stress) and it may be observed to flow like a liquid (hence 'liquefaction').

The presentation will attempt to link the traditional simplified empirical methods with a more theoretical approach based on Critical State Soil Mechanics in an effort to present a unified approach that covers both cyclic and flow liquefaction. Delivered annually by the recipient of the H. Bolton Seed Medal for outstanding contributions to teaching, research, or practice in geotechnical engineering.
Presented by Peter K. Robertson, Ph.D., P.Eng, Professor Emeritus,
University of Alberta, Technical Advisor, Gregg Drilling & Testing Inc.
Dr. Robertson may be best known for work with Cone Penetration testing and his soil behavior type classification systems which has become an industry standard used by engineers every day all over the world. He also is a recognized expert in liquefaction and his CPT-based triggering evaluation methodology is widely used.
Dr. Roberston held the position of Professor at the University of Alberta at Edmonton, where he taught courses, performed research and led research teams, and held important administrative posts for seventeen years. During that period he instructed hundreds of students and supervised many MS and PhD research projects.
He has authored three books, published 86 peer-reviewed papers in the geotechnical literature, and written over one hundred additional papers and reports for conferences and symposia proceedings. Sharing his experiences, research findings and insight is clearly one of the hallmarks of his career.
He has received several prestigious awards, including three R.M. Quigley Awards from the Canadian Geotechnical Society for paper of the year published in the Canadian Geotechnical Journal.
He has furthered the innovative work initiated of the late Professor Seed by advancing field tests for evaluation of liquefaction hazard. Professor Seed led the development of the SPT as a useful field test in liquefaction evaluation. Professor Robertson has led the development of the CPT as an equally or even more important field test for liquefaction hazard evaluation. Both contributions led to major advancements in the state-of-the-art of geotechnical engineering practice. Dr. Roberston is truly one of the pioneers in the advancement of in-situ testing and of our profession.

Guthi Seminar 2016 : "Soil Liquefaction during April 25 Nepal Earthquake" by Dr Manika Maharjan
On 25 April 2015, an earthquake of magnitude 7.8 occurred in Gorkha, Nepal, an actively deforming central Himalayan mountain range, with epicenter approximately 80 km northwest of capital city Kathmandu. Nepal lies on the boundary of two massive tectonic plates, Indian plate and Eurasian plate that collided to form the Himalayas. The continuous subduction of Indian plate under Eurasian plate caused widespread damage of civil infrastructures such as buildings, temples, bridges, highways and liquefaction mainly in the central part of the country. Kathmandu Valley was once a big lake and consists of lake and river sediments known as lacustrine deposits having the tendency to cause liquefaction. Clear evidences of liquefaction in the form of sand boils, lateral spreading and ground failures we... -

"Pile Response to Liquefaction and Lateral Spreading: Field Observations and Current Research"
Abstract:
The lecture focuses on the response of pile foundations to lateral spreading induced by liquefaction. Lateral spreading due to liquefaction of saturated cohesionless soils is a common and extremely damaging phenomenon occurring during earthquakes. It typically happens near waterfronts or in mildly sloping areas, with permanent lateral displacements of the ground ranging from a few centimeters to several meters. First are case histories, starting with a detailed discussion of a well-documented case in Japan followed by a number of comments on the state-of-the art. The second and third subjects are on recent important research results.

Kathmandu Valley was once a big lake and consists of lake and river sediments known as lacustrine deposits having the tendency to cause liquefaction. Clear evidences of liquefaction in the form of sand boils, lateral spreading and ground failures were observed in many regions of the Kathmandu Valley. However, no major ground failure occurred and the extent of damage was less due to liquefaction in this event which might be due to the several other factors.
One reason might be the low intensity of the ground motion (PGA ranging from 0.16-0.2g) is just enough to trigger
the liquefaction and not sufficiently enough to fully weaken the liquefiable materials exhibiting a “marginal” liquefaction. Other reasons might be the groundwater level; which was substantially low due to the dry season.
