October is Earthquake Awareness Month! Today our favorite physicist, Tom Alena along with some international guests, discuss what it’s like living with earthquakes.
Tom Alena lives about 35 air miles from California’s most notorious fault, the San Andreas. This is a transform or slip fault in which two plates slide along each other. Remarkable geologic features, as well as deadly destruction, have resulted from this motion. In Pinnacles National Park two halves of an ancient volcanic field are separated by 195 miles, representing over 20 million years of motion. Smaller time intervals are evident in dry creeks that have been displaced. The notorious San Francisco earthquake of 1906 caused destruction that almost destroyed the city. Tom will take you on a virtual field trip through some of the most amazing aspects of this fault zone.
The primary tectonic plate associated with Chile is the South American Plate. However, Chile’s location at the edge of this plate makes it a region of intense tectonic activity. Specifically, the Nazca Plate is subducting (sliding beneath) the South American Plate along the Peru-Chile Trench, creating a subduction zone. This ongoing process is responsible for the Andes Mountains, frequent earthquakes, and volcanic activity in Chile. Vanessa Fuentes Gandolfi resides in Chile’s capitol, Santiago. She’ll share some of her experiences.
Iceland is called The Land of Fire and Ice for its immense volcanic activity and numerous glaciers. Where there are volcanoes, there are tectonic plates. The precursor to every volcanic eruption is a series of hundreds and in some cases thousands of earthquakes of various magnitudes. Jón Baldur Hlíðberg knows a thing or two about this. His entire life has been spent living on The Rift. The Mid-Atlantic Ridge diagonally slices Iceland in half. Experience what life is like on the North American Tectonic Plate and the Eurasian Tectonic Plate.
