1.The outline of my own handmade seismograph systemImprovement of my own seismograph system has been continued since 1989 when the prototype had been made.These system is whole handmade including seismometers, electric circuits, and auto logging software The details of the system were described including unpublished study .We explain in detail about the electric circuit and the auto logging software for the convenience of making an apparatus like my system. Some notice points in the observation of earthquakes at school were explained in detail, too. Since my system is too dificult to make at school, we developed a new simplified sensor which consists of filmcase and bar magnet, and described in details.2. Making fluxgate magnetometer for geomagnetism observationWe made a magnetometer using a ferrite core and calibrated the sensitivity of the sensor and the noise level of daily variation.3. Softwares for the teaching materials about the earthquake and the earth structureSoftwares which show the propagation of seismic waves and the propagation of tsunamis were developed as PC based numerical simulation for study in the classroom.4. Exemples of seismograms -Near earthquakes-5. Exemples of seismograms -Foreign earthquakes-For the use of teaching material, some characteristic seismograms are shown with helpful comments.

1.自1989年以来，我自己手工制作的地震仪系统对我自己的地震仪系统进行了概述。这些系统都是整个手工制造的，包括地震仪，电路和自动记录软件，该系统的详细信息被描述了不公开的研究，包括未发行的研究。我们在详细介绍了电路和自动登录软件的详细信息。还详细解释了在学校观察地震的一些注意点。由于我的系统过于实践，无法在学校制作，因此我们开发了一个新的简化传感器，该传感器由电影盒和棒磁铁组成，并详细描述2。制造用于地磁观察的磁力磁力计，使用铁氧体芯制造磁力计，并校准了传感器的灵敏度和每日变化的噪声水平。3。有关地震和地球结构的教材软件，这些软件显示了地震波的传播和海啸传播的传播，作为基于PC的数值模拟，用于教室中的研究。4。地震图 - 近地震5。地震图的样本 - 在教学材料的使用前外地震，显示了一些特征性的地震图，并带有有用的评论。
