Taal Volcano, situated at SW part of Luzon Island, Philippines, erupted during 28th to 30th, September 1965 after fifty-four years of quiescence.As an example of a magmatophreatic eruption of basaltic volcano, this paper deals with the course and the ejecta of the eruption with special reference to the horizontal blasts, based both on a paper by MOORE et al. and on the writers field observation. Topography of the island and historical records of eruption are examined from the same viewpoint by literature survey.Taal Volcano is an island in Taal Lake and is 25 km2 in area with a summit crater 2 km in diameter. The volcano island is composed almost of pyroclastic materials which are the product of past magmatophreatic eruptions. Sixteen craters are found on the slope of the main flat cone and they are wide in proportion to their height suggesting their origin to be explosive eruptions.No historical record describes quiet effusion of lava flows, but it indicates explosive nature of eruption.Essential materials responsible for the present eruption was titanaugie-olivine-basalt. The eruption continued for about 60 hours and no lava flow issued. The area of about 60 km2 was covered by new pyroclastic ejecta more than 25 cm thick. New elongate explosion crater was opened by the present fissure explosion on the southwestern slope of the main cone.From the base of explosively rising eruption clouds, horizontal blasts spread out in all directions. The blast is turbulent mixture of mud, lapilli, blocks and crept on the surface of the ground with hurricane velocity and near the crater it spilled over a ridge of 300 m in relative height (summit crater rim). But it tended to spread on lower places as it proceeded further away from the crater. Parts of the blast crossed the lake surface over 2 km and caused much damage to the villages at opposite lakeside. The blasts left giant ripples on the surface of the deposits within 2 km from the crater. The wave-length of the ripples decreases regularly from 15 m to 3 m as the distance from the crater increases.The blasts are regarded to be a low temperature pyroclastic flows. The mobility of the flow is thought to be maintained only by the initial formation of a fluidized system. Because, no delayed vesiculation is expected since the essential material is basaltic in composition, and also because the internal turbulence caused by envelopment of cold air is not great enough, since the temperature of the flow was only about 100°C or below. Magmatophreatic explosion through layers of pyroclastics seems to have been a favourable condition for the initial formation of the fluidized system.

We report a case of GID (gender identity disorder) of the female-to-male type, where her vocal pitch was lowered to her satisfaction by Thyroplasty type 3. The distress of GID patients derives from the contradiction between their sexual physical features and gender self-consciousness. As to the levels of distress and the means patients select to resolve the problems they face, individual variations are great. The present patient did not want either transsexual surgery or hormonal treatment, but merely her vocal pitch lowered. Thyroplasty type 3 successfully lowered her vocal pitch as desired without any complication. Surgical details and key points were described.

Rift zones are characteristic features of Hawaiian volcanoes. They are long narrow zones of flank fissure eruptions but are distinct from ordinary flank eruption sites on stratovolcanoes in that eruptions, and therefore dike intrusions, occur repeatedly at the same general place for a long time and thus cause a considerable amount of lateral spreading. This spreading should somehow be accomodated. Moreover, the stress field should remain the same after accomodation in order for a new dike to intrude in the same orientation. The current spreading episode in Iceland (BJORNSSON et al., 1979) between North American and European plates revealed that the sequence of events in the spreading process is similar to that observed for Hawaiian volcanic activities. This implies that the process of plate separation and accretion is nothing but the activity of rift zones. Constructional plate boundaries may be regarded as composed of a chain of rift zones and associated feeding polygenetic centers. Room necessary for repeated dike intrusion is supplied in the case of spreading centers, by the lateral motion (separation) of lithosphere over asthenosphere. In the case of Hawaii, sliding of the volcanic edifice over a deep sea sediment layer may be the analogous mechanism such as appears to have occurred during the 1975 Kalapana earthquake, as studied by ANDO (1979) and FURUMOTO and KOVACH (1979). Kalapana earthquake had been anticipated by SWANSON et al. (1976) as one of the repeated steps as the east rift zone has continuously dilated. Thus, the primary cause for the long, well developed rift zones of Hawaiian volcanoes may be in the existence of thick enough oceanic sediments serving as a potential sliding plane beneath the volcanic edifices. Lack of rift zones in Galapagos shields which grew over the young ocean floor with rough topography is consistent with this view.

Thyroplasty was performed under local anesthesia on male-to-female transsexuals (MTF/GID) as well as patients with adductor spasmodic dysphonia (AdSD).<BR>There were 31 patients with MTF/GID who underwent type 4 thyroplasty during the period from 1999 to 2006. Voice fundamental frequency (F<SUB>0</SUB>) rose in all patients. Mean preoperative F<SUB>0</SUB> was 135Hz, and postoperatively the mean value was 236Hz. Type 4 thyroplasty requires specialized skill, and was found to be effective for pitch elevation surgery in MTF/GID. <BR>Forty-one patients with AdSD underwent type 2 thyroplasty with Titanium Bridge between December 2002 and December 2005. These patients were followed up 1 year postoperatively with a questionnaire. 70% of the patients judged their voice as "excellent, " and the remaining patients as improved to "good" or "fair". Type 2 thyroplasty is a highly effective therapy for AdSD.

This study examined the reduction in medical expenses achieved by pharmaceutical inquiries at a community pharmacy. The total number of inquiries was 1,053 out of a total of 29,875 prescriptions filled at one community pharmacy (incidence: 3.5%). Pharmaceutical inquiries regarding the elimination of prescribed medicines were classified into two categories: leftover (incidence: 0.76%) and those regarding duplicate prescriptions filled by other institutions or drug interactions (incidence: 0.18%). The doctors accordingly reduced the number of medicines after these inquiries, which led to a reduction in dispensing and medical fees. The reduction in patient medical expenses per prescription from leftover medicines was 1,425 yen (median) for children (under 14 years), 390 yen for adults (15-64 years), and 1,165 yen for elderly patients (over 65 years). The reduction in patient medical expenses per prescription from eliminating duplicate prescriptions was 955 yen for children, 250 yen for adults, and 360 yen for the elderly. The reduction in patient medical expenses from leftover medicines was statistically higher compared with that from duplicate prescriptions for elderly patients (P < 0.01). This difference was because of long-term drug prescriptions for cardiovascular diseases and diseases of the digestive and central nervous systems. Our findings show that community pharmacists can effectively reduce patient medical expenses and increase patient safety by responding to pharmaceutical inquiries and collecting leftover medications.

Volcanoes are generally classified into monogenetic and polygenetic types. Monogenetic volcanoes erupt only once to form smaller volcanoes, such as maars, pyroclastic cones and lava domes. Polygenetic volcanoes erupt repeatedly from the same general vents (summit or main crater) for up to 10⁵ years to form larger volcanoes such as strato-volcanoes (composite volcanoes of Macdonald, 1972) and shield volcanoes of Hawaiian type. Monogenetic volcanoes tend to occur in clusters as flank and post-caldera cones. Some of the clusters are however, independent of polygenetic volcanoes and appear to be equivalent to them. The essential part of the conduit of a monogenetic volcano is inferred to be a simple dike, intruded into a newly formed crack, whereas a long endured pipe-shaped conduit may exist under a polygenetic volcano. The common occurrence of xenoliths in the eruptive products of monogenetic volcanoes may be related to this difference. Various lines of evidence, indicating the existence, depth, shape, volume and internal structure, of magma reservoirs are tabulated. A shallow magma reservoir appears to exist beneath polygenetic volcanoes with one to one correspondence, which is not the case for monogenetic volcanoes. Most flank volcanoes are monogenetic, thus indicating dikes within the polygenetic volcanic edifice. Dike formation is understood as a magma version of hydraulic fracturing. For the dike to intrude and propagate, would require either the increase of differential stress due to a decrease of minimum compression or increase of pore pressure over the sum of the minimum compression and the tensile strength of the rocks. Earthquakes are understood as the generation of elastic waves associated with an acute release of tectonic stress due to faulting. Accumulation of tectonic stress and strain prior to earthquakes is, then, a necessary part of earthquake phenomena in a broad sense, as well as their release after the event. Based on the above-stated understanding, possible mechanical correlations between volcanic eruptions and earthquake occurrences have been studied. Contractional strain around the magma reservoir can cause the squeezing up of magma within an open conduit causing a summit eruption on the one hand, and dike formation resulting in a flank eruption through the increase of pore pressure, on the other. Second boiling triggered by both the magmatic pressure decrease caused by dilatational strain and the dynamic excitation due to seismic waves might have the same effect as contraction. Decrease of minimum compression causing the increase of differential stress leading to dike formation will also contribute to the liklihood of flank eruptions. Both volcanic eruptions and earthquake occurrences can precede each other depending on geographical location in terms of faulting-related stress-strain changes which are calculated by the fault model of earthquakes. Actual possible examples of volcanic eruptions and earthquakes which are allegedly mechanically related are given. In order to demonstrate which mechanism is responsible for the correlation of the two phenomena, continuous strain measurement on and around volcanoes is necessary together with the observation of changes in the level of magma in crater bottoms.

A model is presented which explains the temporal relation between an eruption and a succeeding earthquake, taking a basaltic stratovolcano, Izu-Oshima volcano, as an example. In the model, volcano is assumed to consist of an underground reservoir and a long pipe connecting the reservoir to the surface. As the compressional crustal strain is gradually stored toward the earthquakes to occur, the volcano, located near the potential fault, is also deformed and contracts to some degree. Then the magma in the reservoir is squeezed up through the pipe. The rise of the magmatic head above a certain level in the pipe causes an eruption, which, once started, may proceed as a self-moving machine. Later, when the earthquake occurs, the strain that squeezed up the magma is released. And the head of the magma falls off resulting in the end of the eruption, in case it has still continued. The bottom of the summit crater of Oshima volcano showed remarkable rise and fall in this century amounting to some 400 meters. The bottom can be regarded as the head of the magma column, since red hot glow was frequently observed during the period. There were two maxima of the height of the bottom, January 1923 and June 1951. Shortly after each of the maxima, occurred great earthquakes with magnitude larger than 8, September 1923 and November 1953 along the Sagami trough which runs some 20km northeast of the volcano toward northwest, branching off from the Japan trench. The area including the volcano has been under compressional tectonic stress with the maximum pressure axis in a horizontal N30°W direction, during at least these hundreds of thousand years. On the other hand, recent fault-model studies of the 1923 earthquake indicate that the fault trace of the earthquake almost coincides with the Sagami trough and that the slip vector of the southwestern block, in which the volcano is located, is toward northwest almost horizontal with slight down going component. This tectonic situation implies that the strain which had been accumulated prior to the occurrence of the great earthquakes along the Sagami trough was caused by the same origin, probably the motion of the Philippine sea plate against the Japanese plate, with what has produced the compressive stress field of the volcanic area. The model appears to be successfully applied for the interpretation of the relation between the eruption of Akita-Komagatake volcano which started on September 17, 1970 and the October 16 earthquake with the magnitude of 6.2 at the epicentral distance of 55km. The frequency of explosion discontinuously dropped down to one half or lower level, three days after the earthquake together with the cessation of Strombolian type of eruption. The preliminary mechanism study of the earthquake showed that there is some component of thrust motion indicating the accumulation of contractional strain prior to the earthquake. The volcano to which the proposed model is applied is thus able to be regarded as a sensitive natural indicator of tectonic crustal strain, and also at the same time as being in a near critical condition ready to erupt.
