Strongest aftershock in Italy since 2 days

Very strong earthquake along the coast of Hokkaido and Honshu , Japan
The distance to the coast is at least 50 km. The depth is an additional weakening factor
JMA Japan reports a max. intensity of 5+ which we consider as moderately dangerous
We will start an in-depth report in a few moments

Moderate earthquake in the Southern Peru coastal area
An intermediate depth earthquake very close to the Pan American highway in a sparsely populated desert area.

Deep earthquake below Ecuador
A moderate M4.6 (USGS) or M5.3 (Geofon automatic) has occurred at a depth of 161 km in the Pastaza river area (Amazon like lowlands). It will have been hardly felt by people because of the depth.

Moderate earthquake in Tanzania
The earthquake’s epicenter was located close to the Mtera Reservoir (Mtera dam).  The dam is located on the border between the Dodoma region and the Iringa regions.  Both cities will certainly have felt this moderate earthquake. People in the area are putting the responsibility of these earthquakes on the reservoir. A possible reason could be that water infiltration is lubricating underground layers who are triggering moderate earthquakes from time to time. Mtera Dam is the biggest hydroelectric dam in Tanzania. It measures 660 square kilometers at full capacity. The lake is 56 km long, and 15 km width, and is feed by the Great Ruaha River and the Kisigo River. Its capacity is 80 MW. The lake is considered one of the best places in Tanzania to observe birds, since in it are at the one million dead trees, and he has many shallow areas. Today’s earthquake will certainly have scared the people in the epicenter area but is not strong enough to generate damage. The hydroelectric dam is at the other side of the lake.  We do not know how much Magnitude this dam can resist.

    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.

    City/Village where you felt the earthquake
    MMI II (Very weak shaking) ?
    People :
    Felt by persons at rest, on upper floors or favorably placed.
    MMI III (Weak shaking) ?
    People :
    Felt indoors; hanging objects may swing, vibration similar to passing of light trucks, duration may be estimated, may not be recognized as an earthquake.
    MMI IV (Light shaking) ?
    People :
    Generally noticed indoors but not outside. Light sleepers may be awakened. Vibration may be likened to the passing of heavy traffic, or to the jolt of a heavy object falling or striking the building.
    Fittings :
    Doors and windows rattle. Glassware and crockery rattle. Liquids in open vessels may be slightly disturbed. Standing motorcars may rock.
    Structures :
    Walls and frames of buildings, and partitions and suspended ceilings in commercial buildings, may be heard to creak.
    MMI V (Moderate shaking) ?
    People :
    Generally felt outside, and by almost everyone indoors. Most sleepers awakened. A few people alarmed.
    Fittings :
    Small unstable objects are displaced or upset. Some glassware and crockery may be broken. Hanging pictures knock against the wall. Open doors may swing. Cupboard doors secured by magnetic catches may open. Pendulum clocks stop, start, or change rate.
    Structures :

    MMI VI (Strong shaking) ?
    People Felt by all. People and animals alarmed. Many run outside. Difficulty experienced in walking steadily.
    Fittings :
    Objects fall from shelves. Pictures fall from walls. Some furniture moved on smooth floors, some unsecured free-standing fireplaces moved. Glassware and crockery broken. Very unstable furniture overturned. Small church and school bells ring. Appliances move on bench or table tops. Filing cabinets or "easy glide" drawers may open (or shut).
    Structures :
    Slight damage to buildings with low standard. Some stucco or cement plaster falls. Large display windows broken. Damage to a few weak domestic chimneys, some may fall.
    Environment :
    Trees and bushes shake, or are heard to rustle. Loose material may be dislodged from sloping ground, e.g. existing slides, talus slopes, shingle slides.
    MMI VII (Very strong shaking) ?
    People
    General alarm. Difficulty experienced in standing. Noticed by motorcar drivers who may stop.
    Fittings :
    Large bells ring. Furniture moves on smooth floors, may move on carpeted floors. Substantial damage to fragile contents of buildings.
    Structures :
    Unreinforced stone and brick walls cracked. Low standard buildings cracked with some minor masonry falls. A few instances of damage to buildings of ordinary workmanship. Unbraced parapets, unbraced brick gables, and architectural ornaments fall. Roofing tiles, especially ridge tiles may be dislodged. Many unreinforced domestic chimneys damaged, often falling from roof-line. Water tanks Type I burst. A few instances of damage to brick veneers and plaster or cement-based linings. Unrestrained water cylinders (hot-water cylinders) may move and leak. Some common windows cracked. Suspended ceilings damaged.
    Environment :
    Water made turbid by stirred up mud. Small slides such as falls of sand and gravel banks, and small rock-falls from steep slopes and cuttings. Instances of settlement of unconsolidated or wet, or weak soils. Some fine cracks appear in sloping ground. A few instances of liquefaction (i.e. small water and sand ejections).
    MMI VIII (Severe shaking) ?
    People Alarm may approach panic. Steering of motorcars greatly affected. Structures : Low standard buildings heavily damaged, some collapse. ordinary workmanship buildings damaged, some with partial collapse. Reinforced masonry or concrete buildings damaged in some cases. A few instances of damage to buildings and bridges designed and built to resist earthquakes. Monuments and pre-1976 elevated tanks and factory stacks twisted or brought down. 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.
