The Cascade volcanoes have had more than 100 eruptions over the past few thousand years, many of them explosive eruptions. [21] However, certain Cascade volcanoes can be dormant for hundreds or thousands of years between eruptions, and therefore the great risk caused by volcanic activity in the regions is not always readily apparent.
Google Maps' location tracking is regarded by some as a threat to users' privacy, with Dylan Tweney of VentureBeat writing in August 2014 that "Google is probably logging your location, step by step, via Google Maps", and linked users to Google's location history map, which "lets you see the path you've traced for any given day that your ...
The Juan de Fuca tectonic plate is being subducted under the North American Plate, leading to volcanic activity in the Cascades like at West Crater. In southern Washington state, the Cascade Range, which sits south of the dacitic Garibaldi Volcanic Belt, spans 600 miles (970 km) from British Columbia in Canada to Lassen Peak in northern California in the United States.
The nonprofit is launching a new "Learn on the Lagoon Eco-Boat Tour" to give Fort Pierce elementary school students a rare opportunity to explore the Indian River Lagoon from the water and spot ...
