Volcanic Explosivity Index
April 8 | Geology.com
Volcanic Explosivity Index: The spheres in the illustration above represent the volume of erupted tephra for some of the most widely-known explosive volcanic eruptions. Although most people believe that Vesuvius (79 AD - the Pompeii eruption), Mount St. Helens (1980), and Mount Pinatubo (1991) were enormous, they are very small compared to ancient eruptions such as Wah Wah Springs, Toba, Yellowstone, or Long Valley Caldera.

What Is Hydraulic Fracturing?
April 1 | Geology.com
Horizontal Drilling and Hydraulic Fracturing: Simplified diagram of a natural gas well that has been constructed with horizontal drilling through the Marcellus Shale and hydraulic fracturing on the horizontal portion of the well. The advantage of drilling a well this that in a vertical well, the well bore will only be in the Marcellus Shale for the thickness of the rock unit. However, if the well is turned, drilled horizontally through the shale, and the rocks around the well are fractured, more natural gas will flow into the well. The yield of the well is increased enormously.

Most of Hawaii*s Electric Battery Systems are Paired with Wind or Solar Power Plants
March 31 | Energy Information Administration
Nearly all of Hawaii*s utility-scale battery storage capacity is installed with onshore wind turbines or solar photovoltaic systems, allowing excess electricity from those generators to be stored and used later. As of January 2020, about 30% of Hawaii*s total generating capacity is solar or wind. The non-dispatchable nature of these technologies creates operational challenges for system operators. Pairing batteries with wind and solar systems has proven effective in mitigating the operational challenges. Hawaii plans to generate 100% of its electricity from renewable energy by 2045.

Mineral Rights entitle a person or organization to explore and produce the rocks, minerals, oil and gas found at or below the surface of a tract of land. The owner of mineral rights can sell, lease, gift or bequest them to others individually or entirely. For example, it is possible to sell or lease rights to all mineral commodities beneath a property and retain rights to the surface. It is also possible to sell the rights to a specific rock unit (such as the Pittsburgh Coal Seam) or sell the rights to a specific mineral commodity (such as limestone).

Earthquake at the Boundary Between the Sunda and Australia Plates, near Bali, Indonesia
March 19 | United States Geological Survey
The island of Bali, Indonesia, is located near the boundary of the Sunda and Australia Plates. The Sunda plate is moving to the west-northwest at a rate of about 21 millimeters per year. The Australia plate is moving to the north-northwest at a rate of about 70 millimeters per year. The plates collide to form the Java-Sunda trench, where the Australia plate subducts below the Sunda plate at a relative velocity of about 70 millimeters per year in a north-northwest direction. Many volcanoes in Indonesia have been formed by interactions between the Australia and Sunda tectonic plates; some (but not all) of these volcanoes are shown on the map.

The cores contain a mixture of rock, sediments and water and give researchers insight into what happens as a seamount is ground between tectonic plates. Photo by Demian Saffer.
