Tanzania – Mw 5.2 – Moderate earthquake near Selous Game Reserve

Earthquake Report comment :
No fault lines in the area. However, Tanzania is one of the East African countries located on the East African Rift Zone.
The epicenter of this earthquake is in wilderness area.

Tanzania lies in the East African rift zone and parts of the country are seismically active. The country has a number of active volcanoes and regular earthquakes. 3 significant tectonic plates are pulling away from one another , the Arabian Plate, the 2 African Plates (Nubian and Somalian) and the Indian Plate
Tanzania contains many large and ecologically significant wildlife parks, including the famous Ngorongoro Crater, Serengeti National Park in the north, and Selous Game Reserve and Mikumi National Park in the south.

Indonesia– M 6.3 – Heavy earthquake in Molucca Sea

Earthquake Report comment :
Although this is a heavy earthquake, the depth (hypocenter) of 87 km km would soften the effects. The depth has afterwards been reacalculated as 43 km (more dangerous).
There are NO people living in an area of 100 km around the epicenter.
There are 1795278 people living within a radius of 200 km.
GDACS has issued a GREEN earthquake alert = probably NOT dangerous
NOAA issued a safe message for the Pacific, but is not excluding that such a Magnitude could trigger a limited rather small local tsunami.
First aftershocks happen minutes after the first heavy shock.
Earthquake has been felt as Light Shaking in Manado (177 km from the epicenter)
This area is rich with earthquakes, some of them very powerful.

Chile – M 5.0 – Moderate and fairly deep earthquake just in front of Iquique (Northern Chile)

Earthquake Report comment :
As this earthquake occurred at a depth of 59 km, the impact on buildings and humans , even fairly close to the city of Iquique, was very limited. At this point, only 5 persons have informed USGS that a very weak shaking was experienced.

Iquique has a growing population of more than 227,000.
Iquique is surrounded by a very active fault line which is triggering regular powerful earthquakes.
The city was totally demolished by earthquakes in 1868 and 1877.
The most recent major earthquake occurred on June 13, 2005 and had a Magnitude of 7.9 !
Iquique is located in Northern Chile, one of the richest copper mine areas in the world.  Copper mining, mainly in Quebrada Blanca, Cerro Colorado, and Doña Inés de Collahuasí, is an important industry in Iquique.
