Earthquake
More extensive information will be added here - including tweets about this quake, lives affected (or lost), neighboring communities and cities affected, member comments, "who felt it", and more. Proximity and distance to the earthquake is already availble to logged-in members with an address on their profile. If the member is within 0-1000km of the earthquake, the distance matrix will calculate land transport distance and a the shortest distance between two points ( as the crow flies ). If the earthquake occurred at sea, nautical miles are also calculated.
Members who request notification will automatically receive an email and/or SMS text message for any earthquakes greater than 5.5. If the member adds family contact, the contact will be notified by email that "A Xm earthquake has occurred within Xkm of membername.". All notifications are on an opt-in basis. The IMOK feature will allow the member to single-click on their phone (or in the email) to quickly signal they are fine. IMOK is available for logged in members on an opt-in basis.
The 3D globe (right) will create two pins - one for the earthquake and one for the geographic location of the member viewing this page. If the visitor is not logged in, only one pin for the quake is rendered. The exact position of the moon at the time of the earthquake is included for your interest, and will display illumination %, phase, distance from Earth, the sun, and whether or not the moon was above (or below) the horizon. Some will argue the moon plays no role in influencing earthquakes, and some will argue the opposite. After all, the moon has an effect on tides. Either way, including the appearance of the moon at the exact time of the earthquake is extremely cool. Special thanks to the US Navy (military observatory) for making it possible.

[contentType] => 1 [lastModified] => 1545343820000 [length] => 1581 [bytes] => The December 20, 2018 M7.3 earthquake east of Kamchatka peninsula, Russia, occurred as the result of oblique faulting in the northern Pacific Ocean, near the junction of the Kuril-Kamchatka and Alaska-Aleutian oceanic trenches. Focal mechanism solutions indicate slip occurred on a steeply dipping fault striking to the southwest, or on a moderately dipping fault striking northwest. At the location of this earthquake, the Pacific plate moves towards the northwest with respect to the North America plate at a rate of about 76 mm/yr, subducting beneath and translating past the North America plate at the Alaska-Aleutian trench immediately south of this event. The location, depth, and focal mechanism solution indicate this earthquake may have occurred as the result of interplate faulting along this plate boundary structure, or on a related fault taking up motion between these two plates.
The region surrounding today’s earthquake is an active plate boundary and regularly experiences moderate to large earthquakes. Twenty-one other earthquakes of M6.5+ have occurred within 250 km of this event over the preceding century. Many of these occurred within the Kuril-Kamchatka subduction zone to the west of today’s earthquake. The largest nearby historic event in the Alaska-Aleutian system was a M7.0 earthquake to the east of today’s event in August 1925. A M6.7 event occurred to the northeast of today’s earthquake in December 2003. Events in this region are unlikely to cause earthquake-related damage due to their remote location, far from populations.
