What type of fault is the Nojima fault?
The quake happened along a strike-slip fault – one in which sections of the Earth’s crust scrape past each other horizontally. Japanese scientists have reported a pattern of aftershocks that runs for 50 kilometres, spreading along the Nojima Fault on the island of Awaji and along the Suma and Suwayama Faults, which run …
What type of plate boundary is close to Kobe?
Kobe is located between the sea and the Rokko mountain range and the “Kinki Triangle” which is surrounded by 3 major active faults and subduction zones. The region is located on the Eurasian plate, close to the intersection of the Philippine Sea Plate and the Pacific Plate (Bardet, J.P.).
Was the Kobe earthquake on a destructive plate boundary?
1995 Kobe Earthquake The earthquake occurred along the destructive plate boundary where the Pacific and the Philippine Plate (oceanic) meet the Eurasian (continental) plate. Many freeways and buildings were destroyed, despite the strict building regulations, and 5000 were killed.
Where is the Nojima fault?
Awaji Island
Nojima Fault (野島断層, Nojima Dansō) is a fault that was responsible for the Great Hanshin earthquake of 1995. It cuts across Awaji Island, Japan and it is a branch of the Japan Median Tectonic Line which runs the length of the southern half of Honshu island.
How do strike-slip faults cause earthquakes?
A recent study has revealed extensive data on how strike-slip faults develop over time and eventually cause earthquakes at the Earth’s surface. The cause of strike-slip fault earthquakes is due to the movement of the two plates against one another and the release of built up strain.
What is heave and throw in context of faulting?
In measuring the horizontal or vertical separation, the throw of the fault is the vertical component of the separation and the heave of the fault is the horizontal component, as in “Throw up and heave out”.
Where did the Kobe earthquake occur?
The earthquake hit at 5:46 am on Tuesday, Jan. 17, 1995, in the southern part of Hyōgo prefecture, west-central Honshu. It lasted about 20 seconds and registered as a magnitude 6.9 (7.3 on the Richter scale).
Was Japan prepared for the Kobe earthquake?
Second, Kobe lies in area that many Japanese thought was unlikely to be hit by a major earthquake and thus th residents there were not prepared for a major quake. Kobe is considered one of the nicest cities in Japan and ironically some people even moved there to escape earthquakes.
Why Kobe earthquake was so devastating?
This was because it was built on easily moving ground which LIQUIFIED, allowing building to collapse and sink. The worst effected area was in the central part of Kobe including the main docks and port area. This area is built on soft and easily moved rocks, especially the port itself which is built on reclaimed ground.
How much damage did the Kobe earthquake cause?
The January 17, 1995, earth- quake that devastated Kobe, Japan, caused about $100 billion in prop- erty losses, making it the most expensive earthquake ever to strike an urban area. The earthquake killed 5378 people, damaged or destroyed about 152,000 buildings, and inciner- ated the equivalent of 70 U.S. city blocks.
What type of fault causes earthquakes?
Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.
