Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and slip. Mag_significance = magnitude * 100 * (magnitude / 6.5) pager_significance = red is 2000 : orange is 1000 : yellow is 500 : green is 0 dyfi_significance = min(num_responses, 1000) * max_cdi / 10 earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Local time is the time of the earthquake in your computers time zone. To the south, where the rift is young, extension rates are low.
Click or tap on a circle to view more details about an earthquake, such as location, date/time, magnitude, and links to more information about the quake. A timeline in action The East African Rift is unique in that it allows us to observe different stages of rifting along its length. The services DOC provides are designed to balance todays needs with tomorrows obligations by fostering the wise use and conservation of energy, land and mineral resources. Earthquakes are shown as circles sized by magnitude (red, < 1 hour blue, < 1 day, yellow, < 1 week). Events in this list and shown in red on our real-time earthquake map and list are considered “significant events’, and they are determined by a combination of magnitude, number of Did You Feel It responses, and PAGER alert level. California Department of Conservation administers a variety of programs vital to Californias public safety, environment and economy.
