Montana earthquakes noted in pennsylvania mine‐water pools

A recent paper by daCosta [1959] reported water ‐level fluctuations caused by the Montana earthquake of August 18, 1959, and mentioned the fluctuations registered in three mine ‐ water pools of the Northern anthracite field in northeastern Pennsylvania , ten miles north of Wilkes‐Barre. This paper will discuss the water ‐level phenomena of these pools in more detail. Most of the coal mines near Wilkes‐Barre are idle, and ground water is forming extensive mine ‐ water pools in the underground mine openings. Some of the pools are interconnected by boreholes, tunnels, and other openings through the barrier pillars between adjacent mines.

Water-resources data for deep aquifers of eastern Montana

Water from aquifers of Mesozoic and Paleozoic age in eastern Montana is little used. This report presents maps and tables to assist in the evaluation of the water in terms of possible utility. In the southern third of eastern Montana water from the Madison Group or from the Tensleep Sandstone contains less than 2,000 milligrams per liter dissolved solids and is available in amounts of as much as 3,700 gallons per minute (230 liters per second) from individual wells. Elsewhere, dissolved-solids concentrations of water from Mesozoic and Paleozoic aquifers commonly exceed 1,000 milligrams per liter, well yields range from 5 to about 1,500 gallons per minute (0.3 to 95 liters per second), and well depths generally are greater than 1,500 feet (460 meters).
