On February 6, 2023, a M 7.8 earthquake occurred in southern Turkey near the northern border of Syria. This earthquake was followed about 9 hours later by a M 7.5 earthquake approximately 90 km to the north. This interactive geonarrative describes the tectonic setting in the region, past seismicity in the area, and details of the earthquake rupture.

Groundwater levels in layered aquifer systems like the Virginia Eastern Shore are often monitored using wells in multiple aquifers at the same location. Colors in the simplified cross-section illustration below correspond to the circles representing wells on the map. The list of monitoring-well layers can be used to control the map display of wells for individual aquifers.

USGS is helping identify potential locations in Pennsylvania where additional or updated water-level data may be needed during or after major storm events. Pre-identification of these locations supports expedited decision-making for site selection, resulting in safer and more timely installation of flood monitoring instruments.

This application provides an overview of oil and gas well history of the United States, from 1880 to September 1, 2022. Well history data is aggregated into 10-mile squares indicating the total number of wells and counts of wells classified as oil, gas, dry, injection, hydraulically fractured, and/or horizontal wells.

About this tool The Water-Use Data and Research (WUDR) Program provides financial assistance to State water-resource agencies to improve water-use data. This viewer provides a map interface to locate projects and see the project dates, priorities addressed, and project activities.

This online tool was designed to help identify which wildfire hazard and risk assessments are available across the United States. It provides information about available risk assessments and links to assessment data when publicly available.
