Very strong deep earthquake in the Molucca Sea
A very strong M 6.8 earthquake occurred in the Moluccas sea (Indonesia). The earthquake was felt is a wide area in Indonesia and the Philippines, mainly because of the deep origin of the hypocenter (+100 km reported by USGS)
Based on our experience , earthquakes from this type are mostly harmless and will NOT generate a tsunami.
A radius of many hundred km means that the areas who will have felt this earthquake are Mindanao (Philippines) and Halmahera and Sulawesi in Indonesia.
The epicenter of this earthquake is in the middle of the sea at a safe distance from the nearest island.
BMKG, the Indonesian seismological agency reports a Magnitude of M6.8 at the harmless depth of 88 km. BMKG confirms that there is NO tsunami risk whatsoever.
A lot of red in the listings but it should be green if it should represent danger.

The Japan earthquake occurred on August 25 UTC – Check our page here.

    seismograph - recordingUseful information to read this daily earthquake list
    This earthquake list covers important earthquakes in the world.
    If a more detailed page is present, the earthquake line will be linked to the detailed page.
    For your comfort, we will provide in most cases a Google Satellite Map to give you an idea where the earthquake struck, which terrain it happened and if villages or cities are located in the immediate vicinity. The multi-source approach has been setup to compare values as seismology is not an exact science and needs a lot of calculations. The reference for the time zone is UTC (Coordinated Universal Time, also called GMT). Color explanation if we add some details above the list :
    green color = NOT dangerous for damage or injuries
    orange color = MODERATE risk for damage or injuries
    red color = CONSIDERABLE risk for damage or injuries

    QuakeSOS+ and QuakeSOS free are iPhone applications developed by Armand Vervaeck, the founder of Earthquake Report. The Application simplifies immediate group communication to friends and family members (with your exact GPS location) and is feeding the users with Earthquake Report news. The 0.99 US$ QuakeSOS+ version will support the activities of SOS Earthquakes.

Some pre-1965 infill masonry panels damaged. A few post-1980 brick veneers damaged. Decayed timber piles of houses damaged. Houses not secured to foundations may move. Most unreinforced domestic chimneys damaged, some below roof-line, many brought down. Environment : Cracks appear on steep slopes and in wet ground. Small to moderate slides in roadside cuttings and unsupported excavations. Small water and sand ejections and localized lateral spreading adjacent to streams, canals, lakes, etc.
    MMI IX (Violent shaking) ?
    Structures Many low standard buildings destroyed. Ordinary workmanship buildings heavily damaged, some collapse. Reinforced masonry or concrete buildings damaged, some with partial collapse. Buildings and bridges designed and built to resist earthquakes damaged in some cases, some with flexible frames seriously damaged. Damage or permanent distortion to some buildings and bridges, designed and built to normal use standards. Houses not secured to foundations shifted off. Brick veneers fall and expose frames. Environment : Cracking of ground conspicuous. Landsliding general on steep slopes. Liquefaction effects intensified and more widespread, with large lateral spreading and flow sliding adjacent to streams, canals, lakes, etc.
