This week I wanted to share with you some information on Japan's volcanoes. My country has 118 of them if we count the ones in the ocean surrounding the country. Most of these are doormat but a good handful are considered restless and nine that are either erupting or have a current volcanic warning. A map of these can be seen here Here . One of the many warning systems that are present are Japan Meteorological Agency. This site shares warning and reports for all kinds of resources to help the people know what to do before and after the emergency. This link here shows the current volcanic activity and the risk level.

Week Four.
Welcome back guys!
This is week four of my geology class and the topic for this week is Tsunamis! What a perfect topic for Japan. You see way back in 2011 Japan had a earthquake that caused a deadly tsunami to form. This was the countries worst one in centuries and caused massive fatalities. According to MIT Technology Review there were warning systems in place that sent out a warning after the first quake and helped people and business be ready for the following quakes. In addition to this there are sensors flouting out in the Pacific that are able to read and notify emergency response centers of potential tsunamis. If you click Here you can see how this system works.

Hey all it is Grace!
Welcome to my blog post week three.
This week we studies semismicity, which is how frequently an earthquakes happen in a region.
Once again my country I am writing about is japan which has a high semisicity because of its location under the meeting point of four plates. Today September 9th 2015 there has been three earthquakes over 4.0 in Japan. In the last twenty years there have been twenty five significant earthquakes over 6.0. Yet only two have had death tolls over one thousand the first is January 17, 1995 with a death told of 6,434 and the second was March 11, 2011, which cause a tsunami and took the life of 15,891.
With all this activity japan needed to make some changes to lesson the damage. According to Japanecho.net "Japan’s earthquake resistance standards for buildings have been adopted and revised several times over the years in the aftermath of a major earthquake. Particularly important were the revisions made in the New Building Standards Act enacted in 1981, introducing new earthquake resistance standards. In 1978.The new regulations made it a legal requirement for all new houses, apartment buildings, and high-rise buildings to be designed to sustain only slight cracks in the event of an intermediate-scale earthquake ... and to not collapse even in the event of a major earthquake...In December 1995, the Law for Promotion of Seismic Retrofit of Buildings was passed. ... regular inspections have been carried out and improvements made to the earthquake resistance features of buildings that did not meet the requirements of the 1981 standards.... These measures have been further enhanced by the Japan Building Disaster Prevention Association, which guarantees liabilities and provides information on earthquake preparedness, and through the introduction of a system of tax deductions for improvement work on buildings to make them more resistant to earthquakes."(Japan's). In addtion to structural advances they have also created an earthquake alert system, that is in theory able to help warn them to take cover.

Hey all.
I wanted to share with you a little information about my country of choice and its location in relevance to various plates. My country is Japan and a cool fact is that the plates under these islands are like the four corners, In the sense that four plats meet at practically the center of the islands. These four plates are the Eurasian, Philippines, Pacific and North American. This can be view Here.
This put the islands at high risk for earth quakes and Tsunamis much like the ones in March 2011. The type of boundary that lays under Japan is a convergent boundary. According to page 32 of our text this when one plate sinks under the other. This action is what causes the earthquakes, as well as, forms mountains and islands themselves, often through volcanic activity.

Hey all this is a blog for my geology class at MPC.
My blog will be about the country of japan and how geology relates it the risk and disasters that occur there. The assignment for out first week is to tell you what a natural hazard, a disaster and a catastrophe are.
A Natural Hazard is anything that is a risk to the people in land in a region, that occurs in because of nature. Some examples that both my home state and the country of Japan are at risk for are earth quakes and tsunamis, because of our location on the edge of tectonic plates and the ocean that is next to us.
A Disaster is an contained emergency, such as a river flooding a small town. According to my text book "Natural Hazards" by Keller and Devecchio, it only needs to meet one of four requirements listed below:

- There is a declared state of emergency
- International assistance is requested
